    Default 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.

    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);
     
     
          }
     
    }
