Slip 14 - A) Write a Java program to calculate power of a number using recursion.

Solution :

import java.util.*;

class Slip14A {

    public static void main(String args[]){

        int base,exp;

        Scanner sc =new Scanner(System.in);

        System.out.print("Enter the Base Number : ");

        base = sc.nextInt();

        System.out.print("Enter the Exponent Number : ");

        exp = sc.nextInt();

        int result = power(base, exp);

        System.out.print("Answer : "+ result);

    }

    private static int power(int base, int exp) {

        if(exp!=0){

            return (base * power(base, exp-1));

        }else{

            return 1;

        }

    }

}

Output:
