Write a Java program that mimics the framework for an online movie information system similar to IMDB written in Java. Create an abstract base class, two subclasses, and one interface to provide basic functionality for the system. Use the provided UML, the class descriptions, and the test output to determine the proper behavior for your classes. Create an interface Rateable that: Provides a method vote(int numVotes, int voteScore). Create an abstract class Movie that: Implements the Rateable and Comparable interfaces. Provides the data fields: title, releaseYear, genre, numVotes, and voteScore. Provides four constructors: o Default, no-arg constructor o Three convenience constructors that allow as parameters: the title the title and releaseYear the title, releaseYear, and genre. Provides an abstract getInfo() method. Provides a concrete toString() method that returns the only movie title. Provides a concrete getRating() method that returns: o -1 if numVotes is 0, o voteScore/numVotes otherwise. Implements the Rateable interface’s vote() method by increasing the existing values of numVotes and voteScore by the amount passed in the appropriate parameter. Implements the Comparable interface’s compareTo() method by comparing ratings. Movies should be sorted in descending order, meaning that a higher rating should be considered “less than” a lower rating. Create a concrete class Horror that: Automatically sets the genre to Horror in its constructors. Adds a data attribute for number of deaths, numOfDeaths, with the appropriate getter/setter methods. 2 Provides a getInfo() method that returns “title, genre, releaseYear (rating): numDeaths deaths” with the appropriate values. o Detects if it receives a -1 from getRating() and uses “No ratings” as the rating. o To pass LiveLab’s auto-grader, make sure ratings are limited to one decimal place (see documentation on using String.format() which works similar to System.out.printf()). Create a concrete class Comedy that: Automatically sets the genre to Comedy in its constructors. Adds a data attribute, hasProfanity, to indicate whether there is profanity in the film with the appropriate getter/setter methods. Provides a getInfo() method that returns “title, genre, releaseYear (rating): Profanity/No Profanity” with the appropriate values. o Detects if it receives a -1 from getRating() and use “No ratings” as the rating. o To pass LiveLab’s auto- grader, make sure ratings are limited to one decimal place (see documentation on using String.format() which works similar to System.out.printf()). NOTE: Movie, Horror, and Comedy should provide all of the appropriate accessor/mutator methods for their data fields. For brevity, these are not included in the UML. Main method Create the horror movies: o A Nightmare on Elm Street, 1984, 4 deaths o Final Destination 5, 2011, 94 deaths1 o Saw, 2004, 6 deaths Create the comedy movies: o Napoleon Dynamite, 2004, no profanity o Keeping Up with the Joneses, 2016, profanity o.

React to the following statement: Knowledge is the technology which has increased globalization. Thus, globalization then leads to the need for increased education. Solution Globalization: Globalization is a process of interaction and integration among the people, companies, and governments of different nations, a process driven by international trade and investment and aided by information technology. Knowledge is the technology – globalization: Technology has also enabled the world to become more interconnected, beyond the economic sphere, with greater access to information and communication which is having a profound impact on societies. Information technology was necessary to enable globalisation and this technology emerged from developed countries. It changed the economic relationship between countries because it made knowledge an increasingly important component in the production of goods and services. Knowledge and high tech industries are the fastest growing in the world today and for countries to compete in these sectors they need to invest substantially in education and training. Technology has typically been introduced to developing countries by large multi- national companies doing business there and so the technology used has originated in developed countries, where most of these companies’ research and development takes place. Many argue that this is increasing the power of the MNCs in international markets and weakening the bargaining power of developing countries. According to the United Nations Educational, Scientific and Cultural Organization (UNESCO) in their 2009 World Conference on Higher Education report, Over 2.5 million students were studying outside their home country. UNESCO also predicted that the number of international students might rise approximately to 7 million by the year 2020. The main destinations preferred by international students are the United States, United Kingdom, Germany, France, Canada and Australia. Overall, the number of international students more than doubled to over 2 million between 2000 and 2007. However the sharpest percentage increases of international students have occurred in New Zealand, Korea, the Netherlands, Greece, Spain, Italy and Ireland. Globalization and Education: According to Edward Fiske, “If Americans are to continue to prosper and to exercise leadership in this new global context, it is imperative that we understand the new global forces that we have both shaped and had thrust upon us. The alternative is to be at their mercy”. The effects of globalization have been far-reaching. While the living standards of the world are still highly uneven, 400 million people have moved out of extreme poverty since 1980—more than at any other time in human history. The growth and urbanization of a global middle class is creating huge new markets for goods and services of all kinds. Globalization is often viewed as a zero-sum game in which one nation\'s economic growth comes at the expense.

what animals first evolved true skeletons what animals first evolved true skeletons what animals first evolved true skeletons Solution Evidence of the oldest fossil of multicellular organisms was seemed to be made by smooth, wormlike organisms and are known as furrows. These fossils tell us very less about the animals they belong to except there external shape. The fossils of first large, complex multicellular organisms who were still soft-bodied were found for the first time in Ediacaran organisms(they are named after the place they are found), these organisms resembled modern day jellyfish or worms and disappeared later. In their places, animals of all the modern phyla evolved like jellyfish, corals, sponges, molluscs, flatworms, annelid worms, echinoderms, insects and chordates consisting of both soft and hard body parts. Jawless fish were the one to have consist of skull and were place in vertebrates during the evolution. Arthropods were the first land animals and bony fish and sharks the first water animals to be comprised of true exoskeleton..

Microprocessor An alarm system is to have 4 different devices, each with its sensor. One of the sensors is to have interrupt address 83. Show and explain how that address is created using switches and how the INTA signal is used to enable a tri-state buffer/driver to place the address on the data lines. Solution Sometimes in digital electronic circuits we need to isolate logic gates from each other or have them drive or switch higher than normal loads, such as relays, solenoids and lamps without the need for inversion. One type of single input logic gate that allows us to do just that is called the Digital Buffer. Unlike the single input, single output inverter or NOT gate such as the TTL 7404 which inverts or complements its input signal on the output, the “Buffer” performs no inversion or decision making capabilities (like logic gates with two or more inputs) but instead produces an output which exactly matches that of its input. In other words, a digital buffer does nothing as its output state equals its input state. Then digital buffers can be regarded as Idempotent gates applying Boole’s Idempotent Law because when an input passes through this device its value is not changed. So the digital buffer is a “non-inverting” device and will therefore give us the Boolean expression of: Q = A..

List three branches of the United States government and write a sentence for each that describes its function Solution The three separate branches of government: the legislative, the executive and the judicial. Legislative Branch The legislative branch is made up of the two houses of Congress—the Senate and the House of Representatives. The most important duty of the legislative branch is to make laws. Laws are written, discussed and voted on in Congress. Executive Branch The President is the head of the executive branch, which makes laws official. The President is elected by the entire country and serves a four-year term. The President approves and carries out laws passed by the legislative branch. He appoints or removes cabinet members and officials. He negotiates treaties, and acts as head of state and commander in chief of the armed forces. The executive branch also includes the Vice President and other officials, such as members of the cabinet. The cabinet is made up of the heads of the 15 major departments of the government. The cabinet gives advice to the President about important matters. Judicial Branch The judicial branch oversees the court system of the U.S. Through court cases, the judicial branch explains the meaning of the Constitution and laws passed by Congress. The Supreme Court is the head of the judicial branch. Unlike a criminal court, the Supreme Court rules whether something is constitutional or unconstitutional—whether or not it is permitted under the Constitution..

John is 5 years old and was diagnosed with cystic fibrosis following intestinal obstruction after birth. He has frequent infections despite respiratory therapy. Answer the following question regarding Cystic Fibrosis. 1)John’s parents would like to have another child. What is the probability that the child will have cystic fibrosis? 2)Describe the basic pathophysiology of cystic fibrosis and the effects in the body. 3)What are the effects on airflow of mucus obstruction in the lungs? 4)Why does John have frequent infections? 5)Why does John have fluid-electrolyte imbalances particularly when experiencing a high fever? Solution 1) Since Cystic Fibrosis is an autosomal recessive disease, the chances of its occurrence are 1 in four births. John\'s first child is having Cystic Fibrosis, still, the chance is 25% for the next child to have the disease. The child may or may not have cystic fibrosis. 2) In cystic fibrosis, there is a mutation in the CFTR gene and different mutation in the gene cause different protein formation which results in mild or severe disease. The gene is responsible for the formation of a protein that anchors on the outer walls of the exocrine glands including lungs, pancreas and sweat glands. The encoded protein creates a channel which is responsible for the movement of halogens from inside and outside of the body. the nonfunctioning of the protein results in the blockage of the channels of the affected organs and causes infection and remodeling of the lungs. There is damage in the digestive system due to the accumulation of digestive enzymes. Due to this, there are chances that the patient will acquire chronic infection and proliferation of bacteria in the accumulated mucus in the lungs. 3) The airflow in the lungs gets affected in cystic fibrosis as there is deposition of mucus in the small airways of the lungs. Since the mucus gets lined is dehydrated and is difficult to clear and eventually obstructs the air pathway causing the destruction in alveoli and deposition of foreign particles in the airways. This can lead to frequent chronic infections. 4) The reason behind the frequent infection of John is the mucus deposition in the air pathways which leads to the proliferation of bacteria in the nutrient-rich mucus. These bacteria forms biofilms inside which is difficult for the immune cells to penetrate and which makes the condition severe. 5) This condition of John is due to the improper transfer of ions in the body due to the narrowing of the channels. This gets severe as the body fights with the soaring body temperature as well as the defect in the channels of ions transport..
