Objective: The purpose of this exercise is to create a Linked List data structure that mimics the behavior of the Java Standard Library Version (Java API). The outcomes/results of using the library features should be identical with your own version (My API). However, the underlying implementation should follow with the descriptions listed below. Instructions : Create the following Linked List Data Structure with the given description below in your utils package and use "for loops" for your repetitive tasks. Where to find starter code in my-api package.class : utils.LinkedList package.class : tests.console.week04.LinkedListTest Where to find your JUNIT test in my-api package.class : tests.junit.LinkedListJUnitTest Nested Class that has to be added to LinkedList class package.class : utils.LinkedList.Node Task Check List ONLY "for" loops should be used within the data structure class. There is an automatic 30% deduction, if other loops are used. The names of identifiers MUST match the names listed in the description below. Deductions otherwise. Complete coding Assignment in your "my-api" GitHub Repository. You will not be graded otherwise and will receive a 0, if not uploaded there. Run JUNIT TEST and take a SNAPSHOT of results. Upload PDF of snapshot of your JUnitTest results to Canvas. Description The internal structure of the Linked List is a doubly linked Node data structure and should have at a minimum the following specifications: data fields: The data fields to declare are private and you will keep track of the size of the list with the variable size and the start of the list with the reference variable data. first is a reference variable for the first Node<E> in the list. last is a reference variable for the last Node<E> in the list. size keeps track of the number of nodes in the list of type int. This will allow you to know the current size of the list without having to traversing the list. constructors: The overloaded constructors will initialize the data fields size and data. A constructor that is a default constructor initializes the starting node location first and size to a zero equivalent, that is, constructs an empty list. methods: methods that manages the behavior of the linked nodes. Together, the methods below give the illusion of a index or countable location. Implement these methods within your generic Linked List class. Method Description Header public boolean add(E item) public void add(int index, E item) public void append( E item) private void checkIndex(int index) public boolean contains(E item) public void clear() private E detach(int index) public E get(int index) public int indexOf(E item) private void insertBefore(int index, E item) public boolean isEmpty() private Node<E> node(int index) public E remove(int index) public boolean remove(E item) public E set(int index, E item) public int size() public String toString() Node Data Structure The generic Linked List class includes a static Node class as a nested class, .

The concept of a partially filled array is discussed in subsection 6.1.3. The program is supposed to: a) allocate storage for an array of integers of a size specified by the user b) fill the array partially with increasing values (number of values chosen by the user) c) check that the item at a user specified index position can be removed, maintaining order of other elements d) check that a new item can be added at a user specified index position, also maintaining order of other elements. Study the startup code and complete the program. You need to complete the validity checks for index position specified by the user. Note that only existing items may be removed, but a new item could be added right after the existing items in the list. Sample output from startup code Page 2 of 2 Updated on: 2020-01-23 Sample Output (successful insert/delete) Sample output with invalid delete/insert positions final static Scanner cin = new Scanner(System.in); static int currentSize; // number of values actually in the intList static int[] intList; // reference to the partially filled array storage /** * @param args the command line arguments */ public static void main(String[] args) { out.println("CPS 151 ICA 1 by _________________________"); setup(); printList(intList, "\nOriginal List"); checkDeletion(); checkInsertion(); printList(intList, "\nFinal List"); out.println("\nGoodbye"); } // end main private static void checkDeletion() { // Checking deletion int position = getInt("\nPosition to delete from: "); // check validity of position if (2 + 2 == 5) { shiftUp(position); currentSize--; printList(intList, "\nList after deletion"); } else { out.println("Invalid delete position, no changes made"); } // end if } // end method private static void checkInsertion() { // Checking insertion int value = getInt("\nValue to insert: "); int position = getInt("At what position? "); // check validity of position if (2 + 2 == 5) { shiftDown(position); intList[position] = value; currentSize++; printList(intList, "\nList after insertion"); } else { out.println("Invalid insert position, no changes made"); } // end if } // end method // fills array with increasing values private static void fillArrayInc(final int startValue, final int howMany) { // Validity check if (h ...

The Collection in Java is a framework that provides an architecture to store and manipulate the group of objects. All the operations that you perform on a data such as searching, sorting, insertion, manipulation, deletion, etc. can be achieved by Java Collections. Java Collection means a single unit of objects. Java Collection framework provides many interfaces (Set, List, Queue, Deque, etc.) and classes (ArrayList, Vector, LinkedList, PriorityQueue, HashSet, LinkedHashSet, TreeSet, etc.).

12:19 Notes Compare and contrast the Hubble Space Telescope with James Webb Space Telescope (JwST). Solution 1) Type of light do the telescopes see : Hubble : Hubbleâ€™s main focus is on visible and ultraviolet light. Its instruments can observe a small portion of the infrared spectrum from 0.8 to 2.5 microns, but not to the extent that James Webb can. Instead it focuses its unique ultraviolet (0.1 to 0.4 micron) capabilities. Webb space: James Webb has been designed to focus on the infrared part of the spectrum from 0.6 (red light) to 28 microns (infrared). This means it wonâ€™t be able to see in ultraviolet light like Hubble, but will be able to focus on infrared bright objects like extremely distant galaxies. 2) Size: Hubble : Hubble is 13.2 meters (43.5 ft.) long and its maximum diameter is 4.2 meters (14 ft.) It is about the size of a large tractor-trailer truck. Webb space : James Webb\'s sunshield is about 22 meters by 12 meters (69.5 ft x 46.5 ft). It\'s about half as big as a 737 aircraft. The sunshield is about the size of a tennis court. 3) distances between the telescopes and Earth Hubble : The Hubble Space Telescope orbits around the Earth at an altitude of ~570 km above it. Webb space: James Webb will not actually orbit the Earth - instead it will sit at the Earth-Sun L2 Lagrange point, 1.5 million km away! At the L2 point James Webb\'s solar shield will block the light from the Sun, Earth, and Moon. This will help James Webb stay cool, which is very important for an infrared telescope. I hope this would be helpful ... .

1.What are the consequences of long term unemployment? 2.Should the government help the unemployed? What role do you think the government has in our economy? 3.What should individuals facing long term unemployment do to deal with this situation? Solution 1) the rise in the incidence of longterm unemployment has been \"caused\" by a collapse of outflow rates at all durations of unemployment; while the longterm unemployed do leave unemployment at a slower rate than the shortterm unemployed, this has always been the case and their relative outflow rate has not fallen over time; there is no evidence that, for a given level of unemployment, the incidence of longterm unemployment has been ratcheting up over time; once one controls for heterogeneity of the unemployed, there is little evidence of outflow rates that decline over a spell of unemployment. While these findings suggest that longterm unemployment is not a problem independent of unemployment itself, one should recognize that the experience of longterm unemployment is a horrid one for those unfortunate enough to experience it 2) the Great Depression of the 1930s, recessions -- periods of slow economic growth and highunemployment -- were viewed as the greatest of economic threats. When the danger of recession appeared most serious, government sought to strengthen theeconomy by spending heavily itself or cuttingtaxes so that consumers would spend more, and by fostering rapid growth in the money supply, which also encouraged more spending. In the 1970s, major price increases, particularly for energy, created a strong fear of inflation -- increases in the overall level of prices. As a result, government leaders came to concentrate more on controlling inflation than on combating recession by limiting spending, resisting tax cuts, and reining in growth in the money supply. Ideas about the best tools for stabilizing theeconomy changed substantially between the 1960s and the 1990s. In the 1960s, government had great faith in fiscal policy -- manipulation of government revenues to influence the economy. Since spending andtaxes are controlled by the president and the Congress, these elected officials played a leading role in directing the economy 3) dealing with long term .

1.To a young researcher, what are the advantages of using the method of participant observation? What are the disadvantages? 2. What are ways that gender can shape sociological research? 3. Do you think Zimbardoâ€™s Stanford County Prison (research it) experiment was ethical, or should he have been prevented from conducting this study? Defend your position. 4.Explain how you would develop a representative sample of students on your campus in order to conduct some survey research. Solution Such research involves a range of well-defined, though variable methods: informal interviews, direct observation, participation in the life of the group, collective discussions, analyses of personal documents produced within the group, self-analysis, results from activities undertaken off or online, and life-histories. Although the method is generally characterized as qualitative research, it can (and often does) include quantitative dimensions. Traditional participant observation is usually undertaken over an extended period of time, ranging from several months to many years, and even generations. An extended research time period means that the researcher is able to obtain more detailed and accurate information about the individuals, community, and/or population under study. Observable details (like daily time allotment) and more hidden details (like taboo behavior) are more easily observed and interpreted over a longer period of time. A strength of observation and interaction over extended periods of time is that researchers can discover discrepancies between what participants sayâ€”and often believeâ€”should happen (the formal system) and what actually does happen, or between different aspects of the formal system; in contrast, a one-time survey of people\'s answers to a set of questions might be quite consistent, but is less likely to show conflicts between different aspects of the social system or between conscious representations and behavior. In participant observation,a researcher\'s discipline based interests and commitments shape which events he or she considers are important and relevant to the research inquiry.According to Howell (1972), the four stages that most participant observation research studies are establishing rapport or getting to know the people, immersing oneself in the field, recording data and observations, and consolidating the information gathered. .

Describe the planning system of this organization. 3. Was it effective? If not, why? Part 2 1. Recall a situation in which you made a decision for which the outcome was satisfactory, but not optimal. 2. Describe the reasons you accepted this satisficing decision rather than pushing on to make an optimal decision. Solution Delta Sigma Theta (???) is a not-for profit Greek-lettered sorority of college-educated women dedicated to public service with an emphasis on programs that target the African American community. Delta Sigma Theta Sorority was founded on January 13, 1913, by 22 collegiate women at Howard University. These students wanted to use their collective strength to promote academic excellence and to provide assistance to persons in need. The first public act of Delta Sigma Theta was the Women\'s Suffrage March in Washington D.C., March 3, 1913. Today, Delta Sigma Theta Sorority is the largest African-American Greek-lettered organization.[2] Membership in Delta Sigma Theta is open to any woman who meets the membership requirements, regardless of religion, race, or nationality. Women may join through undergraduate chapters at a college or university, or after acquiring a college degree through an alumnae chapter. Since its founding, Delta Sigma Theta has been at the forefront of creating programming to improve political, education, and social and economic conditions. Delta Sigma Theta has been pivotal in assisting the African American and International communities through education, lobbying, and economic initiatives, including Delta Days at the State and Nation\'s Capitol, Delta Days at the United Nations, Summits and various conferences which focus on pertinent issues of the day. In addition to establishing independent programming, The Sorority consistently collaborates with community and corporate organizations Such as Chase (bank), Habitat for Humanity, Coca-Cola, Wal-Mart, Lawry\'s, and General Electric to further its programming goals. A sisterhood of more than 300,000 initiated members who are predominantly black college-educated women, the sorority currently has over 1,000 chapters located in the United States, England, Japan (Tokyo and Okinawa), Germany, the Virgin Islands, Jamaica, Bermuda, the Bahamas and the Republic of Korea. Delta Sigma Theta is a member of multiple organizations, including the National Pan-Hellenic Council (NPHC) .

1.Astronomers estimate that a low-mass red dwarf star like Proxima Centauri will shine on the main sequence for four trillion years. Speculate why this star would last so much longer than the estimated 600 Gyr. 2.The star Mira is 1.2 times the mass of the Sun and about 10,000 times more luminous than the Sun. Would Mira fit into the table above? Why or why not? Solution 1. To understand why red dwarfs have such long lifespans, weâ€™ll need to take a look at main sequence stars first, and see how theyâ€™re different. If you could peel back the Sun like a grapefruit, youâ€™d see juicy layers inside. In the core, immense pressure and temperature from the mass of all that starstuff bears down and fuses atoms of hydrogen into helium, releasing gamma radiation. Outside the core is the radiative zone, not hot enough for fusion. Instead, photons of energy generated in the core are emitted and absorbed countless times, taking a random journey to the outermost layer of the star. And outside the radiative zone is the convective zone, where superheated globs of hot plasma float up to the surface, where they release their heat into space. Then they cool down enough to sink back through the Sun and pick up more heat. Over time, helium builds up in the core. Eventually, this core runs out of hydrogen and it dies. Even though the core is only a fraction of the total mass of hydrogen in the Sun, thereâ€™s no mechanism to mix it in. A red dwarf is fundamentally different than a main sequence star like the Sun. Because it has less mass, it has a core, and a convective zone, but no radiative zone. This makes all the difference. The convective zone connects directly to the core of the red dwarf, the helium byproduct created by fusion is spread throughout the star. This convection brings fresh hydrogen into the core of the star where it can continue the fusion process. By perfectly using all its hydrogen, the lowest mass red dwarf could sip away at its hydrogen fuel for 10 trillion years. 2. No , Mira does not fit in that because of high mass. .

1.a Which of TCP or UDP is connection-less? Which of TCP or UDP is connection-oriented? What is the difference? b. Name the four components of a process c.. What is the PCB? Solution 1. a. UDP is connection-less TCP is connection oriented TCP is connection oriented â€“ once a connection is established, data can be sent bidirectional. UDP is a simpler, connectionless Internet protocol. Multiple messages are sent as packets in chunks using UDP. TCP rearranges data packets in the order specified. UDP has no inherent order as all packets are independent of each other. If ordering is required, it has to be managed by the application layer. The speed for TCP is slower than UDP. UDP is faster because there is no error-checking for packets. There is absolute guarantee that the data transferred remains intact and arrives in the same order in which it was sent. There is no guarantee that the messages or packets sent would reach at all. b. Components of process are following. 1. Object Program Code to be executed. 2. Data Data to be used for executing the program. 3. Resources While executing the program, it may require some resources. 4. Status Verifies the status of the process execution.A process can run to completion only when all requested resources have been allocated to the process. Two or more processes could be executing the same program, each using their own data and resources. c. Process Control Block (PCB, also called Task Controlling Block, process table, Task Struct, or Switchframe) is a data structure in the operating system kernel containing the information needed to manage a particular process. The PCB is \"the manifestation of a process in an operating system\". .

1. You align 2 lenses together with known focal lengths fi and fa. The equation to deter- mine the equivalent focal length fq is: D.???. ointaining the distance Solution Option (D) 1/f(eq) = 1/f1 + 1/f2, is the correct answer. Explanation - To prove the relation, we consider two thin convex lenses L1 and L2 in contact. Let the foci of the two lenses be f1 and f2 respectively. A point object O is placed. We assume a ray of light from O passing through the first lens L1. It forms an image at I1, in the absence of L2. Then we consider the image formation for the second lens. For the second lens the object is I1. I1 acts as a virtual object fro L2 and the image is formed at I. Let: u = object distance v = distance of image I v1 = distance of image I1 Using lens formula, we know that 1/f = 1/v + 1/u ------------------------------(i) Let us consider each lens separately: Applying sign convention For L1:- f = +f1 v = +v1 u = - u Now substituting them in equation (i), we get: 1/f1 = 1/ (+v1) + 1/ (-u) 1/f1 = 1/v1 -1/u -----------------------? (ii) For L2:- f = +f2 v = +v u = -v1 Now substituting the above in equation (i) we get: 1/f2 = 1/ (v) + 1/ (- v1) 1/f2 = 1/ (v) - 1/ (v1) ------------------------? (iii) Adding the equation (ii) and (iii): 1/f1 +1/f2 = [1/v1 -1/u] + [1/ (v) - 1/ (v1)] 1/f1 +1/f2 = 1/(v1) -1/(u) + 1/ (v) - 1/ (v1) 1/f1 +1/f2 = -1/u + 1/ (v) 1/f1 +1/f2 = 1/v -1/u ------------------------? (iv) Now, if the focal length of the combination of the two lenses L1 and L2 is F and the real image is formed at I (at v distance from the lens) and the object being at O (at distance u from the lens), then: 1/F = 1/v + 1/ (-u) 1/F = 1/v -1/u ----------------------? (v) From (iv) and (v), we get: 1/F = 1/f1 + 1/f2 means - 1 / f(eq) = 1/f1 + 1/f2. This is the relation we have mentioned above. .

Discuss Thomas Maithus theory or hypothesis and its application (if any) to 2015 economies? 4. Is his work still relevant why or why not? Solution MALTHUS, THOMAS ROBERT ( b . near Guildford, Surrey, England, 13 February 1766; d . near Bath, England, 23 December 1834, political economy . Malthus is known in the history of science almost exclusively for his influence on Charles Darwin, exerted almost accidentally. His life, work, and friends were mainly centered on social conditions and political economy, and his work on population was part of these. He did have early training in mathematics, however, and based his arguments on the careful analysis of observed data. Robert Malthus (he appears never to have been called Thomas) was the sixth child of seven born to Daniel Malthus and his wife, the former Henrietta Catherine Graham. Daniel Malthus, a scholar and a friend and admirer of Rousseau, provided a stimulating home life and education for the boy, and later sent him to study with Richard Graves at Claverton and at the Dissenting Academy of Warrington under Gilbert Wakefield. In 1784 Malthus went up to Jesus College, Cambridge, where his tutor was William Frend. He read for the mathematical tripos and graduated in 1788, being ninth wrangler; but he also read widely in French and English history and literature and in Newtonian physics. He had already shown his interest in the practical rather than the abstract. He played games and lived a full social life, apparently unaffected by his cleft palate and harelip. The friends he made at Cambridge influenced the rest of his life; the most important was William Otter (1768 .

If you can browse a file on a Windows network share, but are not able to copy it or modify it, what types of access controls and permissions are probably configured? 4. What is the mechanism on a Windows server that lets you administer granular policies and permissions on a Windows network using role based access? 5. What is two-factor authentication, and why is it an effective access control technique? 6. Relate how Windows Server 2012 Active Directory and the configuration of access controls achieve C-I-A for departmental LANs, departmental folders, and data. 7. Is it a good practice to include the account or username in the password? Why or why not? Solution Answer: 1. Identification, Authentication, and Authorization are the three fundamental elements of an effective security program for information systems. 2.Authentication and Authorization are the two elements, used by the Domain User Admin to create users and assign rights to resources. 3. read and write permissions should be properly configured. The file access type should be set to read only. 4. Group Policy Editor is used to administer granular policies and permissions on a Windows network using role-based access. 5. The two-factor authentication is a process, requires two different type of identification, such as an ID card and a pin code / password. The user must authenticate with two forms of ID to prove thier identity. So it is effective. 6.In Windows Server 2008 R2, permissions can be set for files and folders.o grant a user, access only to files owned by him and prevent him from accessing any others. 7.Including the account or username in the password is absolutely not a good or suggested practice. It is a common starting place for hackers when attempting to log in to someoneâ€™s account or when trying to use another personâ€™s access. .

1. What are the various theories that we use to explain why people commit crimes? How are they broadly categorized? Solution In criminology, examining why people commit crime is very important in the ongoing debate of how crime should be handled and prevented. Many theories have emerged over the years, and they continue to be explored, individually and in combination, as criminologists seek the best solutions in ultimately reducing types and levels of crime. Here is a broad overview of some key theories: Rational choice theory: People generally act in their self-interest and make decisions to commit crime after weighing the potential risks (including getting caught and punished) against the rewards. Social disorganization theory: A personâ€™s physical and social environments are primarily responsible for the behavioral choices that person makes. In particular, a neighborhood that has fraying social structures is more likely to have high crime rates. Such a neighborhood may have poor schools, vacant and vandalized buildings, high unemployment, and a mix of commercial and residential property. Strain theory: Most people have similar aspirations, but they donâ€™t all have the same opportunities or abilities. When people fail to achieve societyâ€™s expectations through approved means such as hard work and delayed gratification, they may attempt to achieve success through crime. Social learning theory: People develop motivation to commit crime and the skills to commit crime through the people they associate with. Social control theory: Most people would commit crime if not for the controls that society places on individuals through institutions such as schools, workplaces, churches, and families. Labeling theory: People in power decide what acts are crimes, and the act of labeling someone a criminal is what makes him a criminal. Once a person is labeled a criminal, society takes away his opportunities, which may ultimately lead to more criminal behavior. Biology, genetics, and evolution: Poor diet, mental illness, bad brain chemistry, and even evolutionary rewards for aggressive criminal conduct have been proposed as explanations for crime. .
