What is a while loop?

While loop is a pre-test loop which means the condition will be first checked then the statement will execute, the while loop repeats the statement till the condition is true. When the condition is false then execution comes out from the loop.

Syntax:

 while (condition){
     // code to be executed
   increment/decrement statement;    // i++
 }

Example:

package quipohouse;
class WhileLoop {
	public static void main(String args[]) {
		// initialization expression
		int i = 1;
		// test expression
		while (i < 4) {
			System.out.println("Quipo House");		
			i++;    // update expression
		}
	}
}

Output:

Quipo House
Quipo House
Quipo House
