Answer 1

public class MyClass {
    public static int power_recursion(int base, int powerof) {
        if (powerof != 0) {
          return base * power_recursion(base, powerof - 1);
        }
        else {
          return 1;
        }
    }
    public static void main(String args[]) {
        int base = 2, powerof = 4;
         
        int result = power_recursion(base, powerof);
 
        System.out.println(result);
    }
}
