Thread: Java program to find n power of any number

Hey guys...I'm trying to make a java program that gets 2 numbers and the 2nd number is the exponent of the first. Example: the first number is 3 and the second number is 2. The value returned will be 3 to the 2 power, or 9. Please make use of if/else statements, while loops, for loops, arrays, and system.out.printlns. Thanks sooooooo much u guys. If u can't use the things I stated it's okay.

also when you write the code, please add comments to it to describe the process of each line

Hi Eldiablo,

Welcome to the forums.

Heres the sample code. Hope it gives you a hint and idea.

 
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
 
 
public class ElDiablo {
 
    private static BufferedReader br= new BufferedReader(new InputStreamReader(System.in));
 
    public  static void main(String[] args)throws IOException
 
     {
 
    String number1,exp; 
    double num1, n,num2,  result = 0;
 
    System.out.print("Enter a number : ");
    number1=br.readLine();
    num1=Double.parseDouble(number1);
 
    System.out.print("Enter the second number : ");
    exp=br.readLine();
    num2=Double.parseDouble(exp);
    n= Double.parseDouble(exp);
    //you can add or play with this part. :) create your own logic in here so that you will not use the math   //function
//    for(double i=0; i<=num2; i++){
//        result = num1 * num1;
//    }
 
System.out.println("Using the Math fucntion" +Math.pow(num1, n));
//    System.out.println("Not using the Math function : " +result);
 
 
      }
 
}
