Write a menu driven program in Java to accept a number and perform the following operations depending on the user's choice:

1. Entered number is a Buzz number or not.
2. Entered number is even or odd.
3. Entered number is positive or negative.

Note: A Buzz number is a number which is either divisible by 7 or has 7 in its unit's place.

import java.util.Scanner;

public class KboatMenu
{
    public static void main(String args[]) {
        Scanner in = new Scanner(System.in);
        System.out.println("Type 1 for Buzz Number");
        System.out.println("Type 2 for Even/Odd");
        System.out.println("Type 3 for Positive/Negative");
        System.out.print("Enter your choice: ");
        int ch = in.nextInt();
        System.out.print("Enter number: ");
        int n = in.nextInt();
        switch (ch) {
            case 1:
            if (n % 7 == 0 || n % 10 == 7)
                System.out.println(n + " is a Buzz Number");
            else
                System.out.println(n + " is not a Buzz Number");
            break;
            
            case 2:
            if (n % 2 == 0)
                System.out.println(n + " is a Even Number");
            else
                System.out.println(n + " is an Odd Number");
            break;
            
            case 3:
            if (n >= 0)
                System.out.println(n + " is a Positive Number");
            else
                System.out.println(n + " is a Negative Number");
            break;
            
            default:
            System.out.println("Incorrect choice");
        }
    }
