Java control flow statements
This document discusses Java control statements including if/else, switch, while, do-while, for loops, break, continue, return, and labeled break/continue. If/else and switch are used for conditional execution. While, do-while and for loops are used for repetitive execution until a condition is met. Break exits the current loop, continue skips to the next iteration. Return exits the current method. Labeled statements allow breaking or continuing from a specific nested loop.

Understand Decision structures in c++ (cplusplus)
The document discusses different conditional statements in C++ including if statements, if-else statements, and nested if statements. It explains the syntax and logic of each statement. The if statement executes a block of code if a condition is true. The if-else statement executes one block if the condition is true and another block if it is false. Nested if statements allow placing if statements inside other if statements to check multiple conditions. Logical and relational operators are used to build conditions.
Flow Control (C#)
Session covers various flow control statements available in C#. Like if-else, switch-case, for, while, do-while, foreach, goto, break, continue, return, throw.
Conditional statements
If statements allow a program to control the flow of execution based on whether a condition is true or false. An If statement contains a condition and one or more branches of code. If the condition is true, the first branch executes; if false, the second branch executes. ElseIf allows multiple conditions to be checked. Nesting If statements means placing an entire If statement inside the True or False branch of another. Select Case provides an alternative to nested If/ElseIf for choosing between multiple options.
Decision control structures
The document discusses different decision making statements in C programming including if, if-else, nested if-else, if-else-ladder, and switch case statements. The if statement executes code if a condition is true, while if-else adds an else block to also handle when the condition is false. Nested if statements allow if blocks within other if blocks. If-else-ladder checks multiple conditions in order. Switch case allows different code blocks based on the value of a variable. Flow diagrams and syntax are provided for each statement type.
Control statements anil
Control statements allow altering the sequential flow of program execution. There are three main types of control statements in C: conditional statements like if-else that allow branching based on boolean conditions, loop statements like while and for that repeat execution of a block of code a specified number of times, and switch statements that choose among multiple code blocks to execute based on a variable's value. Well-structured programs use control statements to make decisions and repeat tasks to process data efficiently.

Conditional statements in vb script
VBScript provides two main types of conditional statements for controlling program flow: the If...Then statement and Select Case statement. The If...Then statement allows executing different blocks of code based on conditional checks, and can include ElseIf and Else clauses. The Select Case statement chooses between multiple blocks of code based on the value of an expression. VBScript also supports looping structures like For...Next, Do...Loop, and While...Wend to repeat blocks of code. These conditional and looping statements allow inserting verification points and error handling in scripts.

It also contains many built-in functions for manipulating strings, dates, and more.
Control structures in c++
Control structures in C++ affect how statements are executed and include sequence, selection, and loop structures. Sequence structures execute statements sequentially, selection structures choose between alternatives using if, if/else, and switch statements, and loop structures repeat statements using do-while, while, and for loops. Common control structures are used to make decisions, repeat actions, and transfer control based on conditions.
Conditional Loops Python
The document discusses different types of loops that can be used when a program needs to repeatedly perform the same actions. It describes while loops, do-while loops, and for loops as well as examples of their uses. Loops allow code to be reused and reduce the number of statements needed compared to writing out repetitive tasks individually. Debugging techniques for loops, like using counters, are also covered.
Jumping statements
The document discusses three types of jumping statements in C language: break, continue, and goto.
1) The break statement terminates the nearest enclosing loop or switch statement and transfers execution to the statement following the terminated statement.
2) The continue statement skips the rest of the current loop iteration and transfers control to the loop check.
3) The goto statement unconditionally transfers control to the labeled statement. It is useful for branching within nested loops when a break statement cannot exit properly.
Program control statements in c#
The document discusses different types of program control statements in 3 categories: selection statements (if, switch), iteration statements (for, while, do-while, foreach), and jump statements (break, goto, continue, return, throw). It provides details on switch statements, including their general form and use of break. It also covers fallthrough in switch statements, which allows continuous execution of consecutive cases without break, and how to force fallthrough using goto. The document concludes with an overview of foreach loops, which iterate over an expression similar to for loops but do not allow changing the iteration variable.

Control statements
The document discusses the flow of control in programs and control statements. There are two major categories of control statements: loops and decisions. Loops cause a section of code to repeat, while decisions cause jumps in the program flow depending on calculations or conditions. Common loop statements are for, while, and do-while loops. Common decision statements include if-else and switch statements. Nested statements and loops can also be used to further control program flow.
Decision making and looping
The document discusses different types of loops in programming languages. It defines looping as repetitively executing a sequence of statements, which is an important concept that allows programs to repeat tasks. There are two main types of loops - entry controlled loops where the test condition is checked before the loop body executes, and exit controlled loops where the test is checked after execution. Common loops in C include the for, while, and do-while loops. The for loop is entry controlled and uses a counter variable, while the while and do-while can use counters or sentinel values and are entry and exit controlled respectively. Selecting the right loop depends on pre-test or post-test needs as well as whether the number of repetitions is known.

Chapter 8 - Conditional Statement
Statements are the basic executable units in C++ programs. They include compound statements grouped in blocks with braces, null statements containing just a semicolon, and conditional statements like if, if-else, nested if, and switch statements. Conditional statements allow program execution to be selected based on conditions. The if statement executes code if a condition is true, if-else executes one of two blocks based on a condition, and switch permits multiple branching based on a variable's value matching case constants.

The document discusses different sorting algorithms and methods. It introduces the concept of sortable objects that implement the Comparable interface and defines sorting algorithms like insertion sort, shell sort, selection sort, bubble sort, and quicksort. It also describes how sorting is implemented for arrays and collections in Java and the classes and methods involved in the sorting process.
Chapter 17
Recursion is a method that calls itself, directly or indirectly. It is used to solve repetitive problems like calculating factorials and solving the Towers of Hanoi puzzle. The factorial example shows recursion can be used to calculate N! by defining it as N * (N-1)! and base cases where 0! = 1. Similarly, the Towers of Hanoi is solved recursively by breaking it down into moving all disks but the largest, moving the largest disk, and moving the remaining disks.

This document discusses working with strings in Java. It covers concatenating and examining strings, locating characters within strings, comparing strings, modifying strings using StringBuffer, reading and writing files, and parsing strings using StringTokenizer and StreamTokenizer. The key classes covered are String, StringBuffer, FileInputStream, FileWriter, StringTokenizer, and StreamTokenizer.
Chapter 15
Exceptions in Java programs can be handled using try/catch blocks. When an exception occurs, processing stops and the JVM searches for a catch block to handle the exception. If no catch block is found, the program terminates. Exceptions are classified in a hierarchy with Throwable at the top. Exceptions can be caught specifically or generally from more specific to more general. The finally block is used to perform cleanup actions regardless of whether an exception occurred.
Chapter 14
This document discusses maps, concrete map implementations, retrieving values from maps by key, custom collection classes, and linked lists. It provides examples of how maps associate keys with values and how to retrieve values from a map using keys. It also describes linked lists as collections where each node is linked to the next and can be traversed in one or two directions, and explains the hierarchy of nodes in a linked list.

A two-dimensional array can be thought of as a series of one-dimensional arrays stacked on top of each other. It has rows and columns. To declare a two-dimensional array, use int[][] and specify the number of rows and columns by initializing it with new int[rows][columns]. A two-dimensional array can be iterated through using nested for loops, with the outer loop iterating through rows and the inner loop iterating through columns.
Chapter 10
An array is an ordered collection that stores elements of the same type within a single variable name. Elements are accessed via an index number that starts at 0. Arrays can be declared with a type and size, then instantiated using new. Values are assigned using the index operator. The length property returns the number of elements in the array. Arrays are objects that are passed by reference, but intrinsic element types within arrays are passed by value.
Chapter 09
An interface defines a contract that classes implement by providing the interface's methods but allowing flexibility in how they are implemented. Interfaces cannot be instantiated and can define constants but not fields or method implementations. A class can implement multiple interfaces. The Debuggable interface defines displayStatus and displayError methods to allow classes like Ball and Wall to output debugging information even though they don't inherit from the same class. Interfaces are used when classes don't have an "is-a" relationship but share capabilities, and to allow multiple inheritance which Java doesn't normally support.
Chapter 08
This document discusses specialization and inheritance in object-oriented programming. It explains that specialized classes inherit properties and methods from a parent or base class, and that inheritance allows for code reuse by permitting new classes to derive from existing classes without reimplementing their functionality. The document also covers protected access, using the super keyword to call parent constructors, polymorphism which allows specialized objects to be treated as general types, and abstract base classes which define common properties for derived classes without being instantiated themselves.
Chapter 07
This document discusses object-oriented programming and classes. It covers refactoring classes to perform single tasks, setting an object's state with member variables, implementing methods for an object's behavior, encapsulating an object's responsibility, considerations for good program design, method overloading for optional arguments, overloading constructors, and an example of overloading the Ball and HWall classes.
Chapter 06
The document discusses event-driven programming concepts like event sources, listeners, and mouse events. It explains that event sources raise events that are responded to by event listeners. It provides an example of a MouseClick applet that draws ovals in response to mouse click events. It also covers using timers to raise events at intervals and implementing anonymous inner classes to listen for timer events.
Chapter 04
Variables store values within methods and can change as the method processes data. There are different types of variables such as local variables, which only maintain their value within the block of code they are declared in. Operators are symbols that perform actions in a program, such as assignment (=), mathematical (+,-,*,/), and relational (<,>,==,!=) operators. Constants are variables designated with the final keyword that have a fixed value that cannot be changed.
Chapter 03
This document discusses key concepts of object-oriented programming including classes, interfaces, encapsulation, data hiding, delegation, fields, access modifiers, methods, constructors, static members, and the this keyword. It explains that classes define public interfaces and private implementations, and that encapsulation involves containing all class responsibilities. Fields hold class data, and access modifiers control visibility. Methods define behavior, and accessor/mutator methods are used to follow data hiding. Constructors initialize objects, and static members are shared among instances. The dot operator indicates class/object membership.
Chapter 02
This document provides an overview of key concepts in object-oriented programming and Java, including models, classes, objects, fields, methods, object relationships, and the steps to write a Java program. It explains that classes define types through their characteristics and behaviors, while objects are instances of classes. Fields define object properties and methods describe capabilities. The document also covers compiling Java code, types of Java programs, and basic analysis of a HelloWorld example program.
Chapter 01
The document summarizes the history and development of computers from ancient counting devices like the abacus to modern PCs. It discusses early inventions in the 19th century that helped develop basic computer components. During World War II, the first generation of computers was developed for code breaking and calculations. The second generation saw transistors replace vacuum tubes and software stored on punch cards. Integrated circuits led to smaller, more powerful third generation computers. The fourth generation saw affordable personal computers introduced. The document then defines computer hardware and software components.
13 java in oracle
This document provides an introduction and overview of using Java stored procedures in Oracle databases. It discusses the advantages of using Java over PL/SQL, how to create and load Java classes into the database, how to define call specifications for Java methods, debugging and resolving issues, and using tools like Loadjava and Toad. The document is intended to educate developers on Oracle's Java stored procedure capabilities.
Java tut1 Coderdojo Cahersiveen
This document provides an overview of the Java programming language. It discusses key features such as platform independence, object-oriented programming principles like inheritance and polymorphism, automatic memory management, and security features. It also covers basic Java concepts like primitive data types, variables, operators, flow control statements, methods, and classes.
My 3 min pitch pack
This document outlines a business proposal, beginning with introducing the person or company presenting the proposal and where they are based. It then describes the business problem or idea in bullet points, keeping it simple. The proposal discusses the solution to the problem and how the business model would make money, such as through marketing and sales. It provides an overview of potential financials and lays out a future action plan, including what has been done so far, next steps, required funding, and needed personnel.

Euro 2024 Belgium's Rebirth the New Generation Match the Golden Era.docx
The Golden Group is over. Can a new group step up? Two years ago, Kevin De Bruyne plunged Belgium’s Euro 2024 plans into disorder when he claimed the team was “too old” to win in an interview with The Protector. That Belgian squad had 10 players over 30 and the maximum average age of any Euro Cup 2024 team at the competition. A group-stage exit and just one goal at the World Cup put Belgium on course for a restructure.

Coach Domenico Tedesco has managed a tactical shakeup and a regular exit for some of the oldest players. Experienced bests remain, not least the 37-year-old Jan Vertonghen in defense, the 32-year-old De Bruyne himself in midfield, and 31-year-old Romelu Lukaku up visible.
Still, younger actors like De Bruyne’s Manchester City partner Jeremy Doku bring fresh vitality to the team. Euro Cup Germany Qualifying unbeaten with just four goals allowed from eight games was a welcome sign of accomplishment back on track under Tedesco.
The only other squad in Group E besides Belgium to UEFA Euro 2024 qualify unbeaten, Romania was awestruck by winning a group that also checked Switzerland and Israel. Still, Euro 2024 will test a squad sorely lacking in top-level skill.

Psaroudakis: Family and Football – The Psaroudakis Success Story
Psaroudakis, a name that resonates with football fans around the globe, is a testament to the powerful synergy between familial support and individual passion. Born on March 10, 1992, in the historic city of Heraklion, Crete, Psaroudakis’ journey to international football stardom is a compelling narrative of dedication, perseverance, and unwavering family support. His story not only highlights his athletic prowess but also underscores the crucial role his family played in shaping his career and character.
Psaroudakis’ early life in Heraklion was deeply influenced by a supportive and nurturing family environment. His father, a former semi-professional footballer, recognized Psaroudakis’ potential from an early age. Acting as his first coach, his father’s guidance was instrumental in igniting Psaroudakis’ passion for football. This paternal influence instilled in him a strong work ethic and fundamental skills that would become the foundation of his future success. His mother, a dedicated homemaker, provided a stable and nurturing environment, ensuring that Psaroudakis could pursue his dreams without any hindrances.
From a young age, Psaroudakis showed an innate talent for football. Growing up in Heraklion, he spent countless hours playing football in local parks and streets with friends and family. His natural ability was evident even in these informal settings, and his enthusiasm for the game was infectious. By the age of five, Psaroudakis had joined a local youth football club, where his skills began to flourish. His father’s role as his first coach during these formative years was crucial, as he emphasized not only technical skills but also the importance of discipline and teamwork.
The transition from playing in local parks to joining a structured football environment marked a significant step in Psaroudakis’ journey. At the age of ten, he joined the youth academy of OFI Crete, one of Greece’s most esteemed football clubs. This move marked the beginning of a more rigorous and professional approach to his training. The academy environment was demanding, focusing on honing technical abilities and instilling values of sportsmanship and dedication. Psaroudakis’ dedication to his craft was evident as he quickly rose through the ranks, becoming a standout player in the youth teams.
The support of Psaroudakis’ family was unwavering during this critical period. His father continued to be a source of guidance and mentorship, while his mother ensured that he had everything he needed to succeed. Their collective efforts created a balanced environment where Psaroudakis could focus entirely on his development as a footballer. This familial support was not just about providing the basics; it was about creating an environment where Psaroudakis felt encouraged and motivated to pursue his dreams relentlessly.
As Psaroudakis transitioned from the youth academy to professional football, the challenges became more significant.

Chapter 05
- 2. 5 Branching Allows different code to execute based on a conditional test. if, if-else, and switch statements
- 3. 5 If, Else, and Else-If if Statements “If the sky is blue, I’ll ride my bike.” else Statements “If the sky is red, I’ll drive; else (otherwise) I’ll ride my bike.” Else-if Idioms “If the sky is blue, I’ll ride my bike; else if the sky is red, I’ll drive, else I’ll walk.”
- 4. 5 Nested if Statements if statements can be nested (combined) within other if statements to account for multiple conditions. If the sky is blue If there are clouds in the sky Do something for blue sky, cloudy days Else Do something for blue sky, cloudless days Else Do something for non-blue sky days
- 5. 5 The switch Statement switch statements are an efficient way to choose between multiple options. Easier to expand options than else-if structures Easier to read than multiple else-if structures Use the break keyword to prevent “falling through” to next statement
- 6. 5 Switch Evaluation switch statements evaluate int values: int x = 3; switch(x) { 1: x += 2; break; 2: x *= 2; break; 3: x /= 2; break; }
- 7. 5 Logical Operators Combine or negate conditional tests Logical AND (&&) “The value of x is greater than 10 and the value of x is less than 20” (x > 10) && (x < 20); Logical OR (||) “The value of x is greater than 10 or the value of x is less than 5” (x > 10) || (x < 5); Logical NOT (!) “The value of x is not greater than 10” ! (x > 10);
- 8. 5 Looping What is iteration? Iteration is a structure that repeats a block of code a certain number of times, or until a certain condition is met.
- 9. 5 The while Loop “As long as this condition is true, execute this code” while ( counter < 11) { counter++; } Might not execute if the condition is already false
- 10. 5 The for Loop Includes (optional) arguments for: An initialization variable A conditional test An action for ( int counter = 1; counter < 11; counter++ ) { System.out.print(counter + “ ”) }
- 11. 5 The do...while Loop “Take this action, while this is true” int value = 10; do { value = value + 2; } while ( value < 10 ); Ensures at least one execution of code
