Compute Exponent in Java

Submitted by donbermoy on Friday, December 26, 2014 - 21:06.

This tutorial will teach you how to create a program that will compute exponent in java. So, now let's start this tutorial! 1. Open JCreator or NetBeans and make a java program with a file name of powExponent.java. 2. Import the io package library:

import java.io.*;

3. We will initialize variables in our Main, variable in for BufferedReader as our input, num and power as Integer.

        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        
        int num;
        int power;

4. Now, we will have inputting for the base number and the exponent. Have the code below:

        System.out.print("Enter a number:");
        num = Integer.parseInt(in.readLine());
        System.out.print("Enter an exponent:");
        power = Integer.parseInt(in.readLine());

5. Lastly, we will display compute the exponential number using the Math.pow method.

        System.out.print("The answer is:" + Math.pow(num,power));

The Math.pow method has the following parameters of a base number and the exponent (basenumber,exponent). Then it will compute the exponential number. Output: output

Here's the full code of this tutorial:

import java.io.*;
public class powExponent {
        public static void main(String args[]) throws IOException{
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        
        int num;
        int power;
        
        System.out.print("Enter a number:");
        num = Integer.parseInt(in.readLine());
        System.out.print("Enter an exponent:");
        power = Integer.parseInt(in.readLine());
        
        
        System.out.print("The answer is:" + Math.pow(num,power));
        }
        
}
