Control Structures in Java

Selection Control Structures: Allow for alternative courses of action based on conditions. This is achieved through if, else if, and else statements.
Repetition (Loop) Structures: Enable the repeated execution of a block of code. There are several types, each suited for different scenarios:
- for loop: Used when the number of repetitions is known in advance. It controls the loop using an initialization, a condition, and an increment/decrement statement.
- while loop: Used when the number of repetitions is unknown. The loop continues as long as a specified condition remains true. The condition is evaluated before each iteration.
- do-while loop: Similar to the while loop, but the condition is checked after each iteration. This guarantees at least one execution of the loop body.

Loop Functionality

Loop Purpose: To repeatedly execute a set of instructions until a certain condition is met.
Counter in a Loop: A variable used to keep track of the number of iterations. It's typically incremented (or decremented) within the loop.
while Loop Structure: The statements to be repeated are placed inside the body of the while loop, which is enclosed within curly braces {}.
while Loop Condition: The control condition is tested at the beginning of each iteration.
while Loop Execution: If the control condition is true, the loop body is executed. If false, the loop terminates.
Incrementing a Counter: In pseudocode, counter = counter + 1 or counter += 1 adds 1 to a counter.

Pseudocode and Variable Declaration

Pseudocode Variable Declaration: Variables are typically declared using a statement like DECLARE variableName. The specific syntax can vary depending on the pseudocode style used.
Increment Operation Placement: The increment operation should be placed inside the while loop body, usually at the end, to ensure proper iteration.

Test your knowledge of iterative control statements such as while, do-while, and for loops in Java. This quiz also covers the concept of control structures and the order in which instructions are carried out in a Java program.
