While Loop Statements :

While loop is most used loop in programming. We put the condition with in the while loop and if condition satisfied then the while block executes otherwise break the loop. You can use any counter to iterate the loop. This type of control structure repeat the task certain number of times. It is more easier to understand in comparison to for loops.

Syntax :

//statement
}

When executing, if the expression result is true then statement inside the loop will get executed and it will continue as long as the expression result is true.

Example :

Here is Simple example of while loop.

package looping;

class WhileLoop {
	public static void main(String[] args) {
		int i = 1;
		System.out.println("While loop example");
		// Using while loop
		while (i <= 10) {
			System.out.println("Hello " + i);
			i++; // incrementing i with 1
		}
	}

}
