Create a new NetBeans project from scratch named PowerDemo. Write a method that uses recursion to raise a number to a power. The method should accept two arguments: the number to be raised and the exponent. Assume that the exponent is a nonnegative integer. Demonstrate the method in a program. The main method will provide the testing code for using user input for the recursive method.

Answer #1

Directly copy the code in netbeans and run

import java.io.*;
class Power
{
public static void main(String args[]) throws IOException
{
BufferedReader br = new BufferedReader(new
InputStreamReader(System.in));
Power obj = new Power();
System.out.print("Enter number : ");
int x = Integer.parseInt(br.readLine());
System.out.print("Enter power : ");
int y = Integer.parseInt(br.readLine());
System.out.println("\n" +x +"^" +y +" = "+obj.findPower(x,y));
}
int findPower(int x, int y)
{
if(y==0)
return 1;
else if(y==1)
return x;
else
return x*findPower(x,y-1);
}

    RecursiveExponent.java Write a recursive function that accepts two arguments into parameters x and y, and which returns the value of x raised to the power y. Hint: exponentiation is equivalent to performing repetitions of a multiplication. For example, the base 4 raised to the 6th power = 4*4*4 * 4 * 4 * 4 = 4,096. The only file that you need to create is RecursiveExponent.java. Your main method should prompt the user to supply the base and exponent values...
