Java For Loops are fundamental for executing repetitive tasks in programming. They consist of initialization, condition, and iteration steps, and are crucial for traversing arrays and handling data. Variations like For-Each and Enhanced For Loops simplify iterations, while Nested For Loops are ideal for complex structures. Understanding their syntax and common pitfalls is key to effective Java development, with applications ranging from number sequences to algorithmic challenges.

The For Loop enables repeated execution of a code block based on a boolean condition
Initialization
The starting point for the loop control variable
Termination Condition
The condition that must evaluate to true for the loop to continue
Increment/Decrement Operation
The operation that modifies the loop control variable after each iteration
The 'for' keyword followed by components enclosed in parentheses and a block of code within braces
Used when the number of iterations is not predetermined, executing the loop as long as the condition evaluates to true
Ensures the loop body is executed at least once by checking the condition after the loop's first execution
Simplifies iterating over arrays and collections by abstracting away the need for an index variable
For Loops are commonly used to traverse arrays and manipulate their elements
For Loops can be utilized to perform a variety of tasks such as generating sequences, identifying prime numbers, or computing factorials

In Java, a ______ Loop is used to run a block of code multiple times, which is controlled by a boolean condition.

01
Use case of While Loops in Java
While Loops: Ideal when iteration count is unknown; loop continues while condition is true.
02
Execution guarantee in Do-While Loops
Do-While Loops: Executes body at least once; condition checked after first run.
