Program:

            /* ............... START ............... */
                
public class JavaPowerOfNumberUsingWhileLoop {

	public static void main(String[] args) {

		int base = 2, exponent = 3;

		long result = 1;

		while (exponent != 0) {
			result *= base;
			--exponent;
		}

		System.out.println("Answer = " + result);
	}

}
                /* ............... END ............... */
        

Output

Answer = 8

Notes:

  • In this program, base and exponent are assigned values 2 and 3 respectively.
  • In the next step we keep on multiplying result by base until exponent becomes zero.
  • Result is : 1 * 2 * 2 * 2 = 8
