Loops in Java – While Loop 

				
					package practice;

public class WhileLoop {

	public static void main(String[] args) {
		int i = 0;
		while (i < 5) {
		  System.out.println(i);
		  i++;
		}
	
	}

}

Explanation

Loops are used in programming to repeat a block of code multiple times. Instead of writing the same line again and again, you can use a loop to automate repetition, which makes code shorter, cleaner, and more powerful.

How the while Loop Works:

  1. int i = 0; → Initializes the loop variable.

  2. while (i < 5) → Checks the condition before executing the block.

  3. System.out.println(i); → Prints the value of i.

  4. i++; → Increases i by 1.

  5. This repeats until the condition i < 5 becomes false (i.e., when i = 5).
