Question:-

Write a menu driven program in Java to enter a 4 digit number. Perform the following operations depending upon the user's choice.

1. Check whether the entered number is a tech number or not.
2. Check whether the entered number is a buzz number or not.
3. Exit the program.

Code:-

import java.util.*;

class Number

{

public static void main(String s[])

{

Scanner sc = new Scanner(System.in);

System.out.print("Enter a four digit number: ");

int n=sc.nextInt();

System.out.println("1. Checks Tech Number.");

System.out.println("2. Checks Buzz Number.");

System.out.println("3. Exit the program. ");

System.out.print("\n Enter the choice: ");

int ch=sc.nextInt();

switch(ch)

{

case 1:

if(isTech(int n))

System.out.println("Number is a Tech Number.");

else

System.out.println("Number is not a Tech Number.");

break;

case 2:

if(isBuzz(int n))

System.out.println("Number is a Buzz Number.");

else

System.out.println("Number is not a Buzz Number.");

break;

case 3:

System.exit(0);

}

} // main()

static boolean isTech(int n)

{

int s=n/100 + n%100;

s*=s;

return (s==n);

}

static boolean isBuzz(int n)

return ((n%7==0) || (n%10==7));

} // end of class
