while loop

We use while loop in Java Programming to certain number of iterations. And it will not work like for loop. Let’s check it in listing 3 for details, but in the listing 3 we use the same program which we did in listing 2. But we will change for loop in while.

Listing 3: Use of While Loop in Java Programming

public class WhileLoop{
  public static void main(String args[])
  {
    //printing in ascending order
    //from 1 to 10
    //using increment operator
    int i = 1;
    while(i <= 10)
    {
      System.out.print(i+" ");
    i++;
    }
    System.out.println();
    //printing in descending order
    //from 10 to 1
    //using decrement operator
      i = 10;
    while (i >= 1)
    {
      System.out.print(i+" ");
      i--;
    }
  }
}
