How to write while loop statements

class LoopSamples {

 public static void main(String[] args) {
  int x = 1;
  while (x < 2) {
   System.out.println(x);
   ++x;
  }
 }
}

The output will be: 1

How to write do while loop statements

 public static void main(String[] args) {

   System.out.println(x);
   ++x;
  } while (x < 2);
 }
}

The output will be: 1
Note: The loop will exected atleast one ( first) time

How to write for loop statements

class LoopSamples {

 public static void main(String[] args) {
  for (int i = 0; i < 10; i++) {
   System.out.println("i is " + i);
  }

  int y = 6;
  for (int x = 0; (x < 2); x++, y++) {
   System.out.println("x is " + x);
   System.out.println("y is " + y);
  }
 }
}
