Question

public class Q7 {
    public static void main(String[] args) {
        System.out.println("Math is fun");
        //write your logic to continuously get one of the below options and print the result
        //1.reciprocal (1/x), 2.root (x^1/2), 3.cube (x^3), 4.Quit
        //get the number x as input from the user each time
        //hint:- x^n= Math.pow(x,n)
    }
}

need help in java

import java.util.Scanner;
public class Q7 {
    public static void main(String[] args) {
        System.out.println("Math is fun");
        Scanner scan = new Scanner(System.in);
        int n;
        double x;
        while (true) {
            //write your logic to continuously get one of the below options and print the result
            System.out.println("1.reciprocal (1/x), 2.root (x^1/2), 3.cube (x^3), 4.Quit");
            n = scan.nextInt();
            if (n == 4) {
                break;
            }
            else if(n>=1 && n<=3){
                System.out.print("Enter value for x: ");
                //get the number x as input from the user each time
                x = scan.nextDouble();
                if(n==1){
                    System.out.println(1/x);
                }
                else if(n==2){
                    System.out.println(Math.sqrt(x));
                }
                else{
                    System.out.println(Math.pow(x,3));
                }
            }
            else{
                System.out.println("Invalid input");
            }
        }
