Java Program to Calculate the Power of a Number

In this program, you'll learn to calculate the power of a number in Java.

Calculate the Power of a Number using a For Loop

	public class Power {
	public static void main(String[] args) {
	int base = 3, exponent = 3;
	long result = 1;
	for (int i = 0; i < exponent; i++) {
	result *= base;
	}
	System.out.println(base + " to the power of " + exponent + " is equal to " + result);
	}
	}

Calculate the Power of a Number using a While Loop

	public class Power {
	public static void main(String[] args) {
	int base = 3, exponent = 3;
	int i = 0;
	long result = 1;
	while (i < exponent) {
	result *= base;
	i++;
	}
	System.out.println(base + " to the power of " + exponent + " is equal to " + result);
	}
	}
