Write a program which displays the following list on the screen and asks the user to enter either 1 or 2 and perform one of the operations based on the user’s input. If the user enters any other character other than 1 or 2 then display “wrong choice”.

LIST OF OPERATIONS

1. Buzz Number

                     2. Consecutive Odd numbers

Note:

A BUZZ number is a number which either ends with 7 or is divisible by 7.

Sample input

27

Output

27 is a Buzz number

Sample input:

46

Output:

46 is not a Buzz number

Two numbers are said to be consecutive odd numbers if both the numbers are odd and the difference between them is 2.

Sample input

11

15

Output:

11 and 15 are not consecutive odd numbers

Sample input

21

23

Output:

21 and 23 are consecutive odd numbers

Answer 1

8 { 1 import java.util.Scanner; 2 3 - public class MyClass 4 public static void main(String args[]) { 5 Scanner sc = new Scanner(System.in); 6 7 System.out.print("Enter either 1 or 2: "); int choice - sc.nextInt(); 9 10 if (choice != 2 && choice != 1) 11 System.out.print("wrong choice"); 12 else 13 - 14 if (choice 1) 15 16 System.out.print("Enter a number: "); 17 int n = sc.nextInt(); 18 if(n%7 == 0 Il n % 10 == 7) 19 System.out.print(n " is a Buzz number"); 20 else 21 System.out.print(n + is not a Buzz number"); 22 } 23 else 24- 25 System.out.print("Enter a number: "); 26 int a = sc.nextInt(); 27 int b = sc.nextInt(); 28 29 if((a+2 == b || 6+2 == a) && a%2 == 1) 30 System.out.print(a + + b + are consecutive odd numbers"); 31 else 32 System.out.print(a and + b + are not consecutive odd numbers"); 33 34 35 36 + { and " + }

Enter either 1 or 2: 1 Enter a number: 27 27 is a Buzz number

import java.util.Scanner;

public class MyClass {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
  
System.out.print("Enter either 1 or 2: ");
int choice = sc.nextInt();
  
if(choice != 2 && choice != 1)
System.out.print("wrong choice");
else
{
if(choice == 1)
{
System.out.print("Enter a number: ");
int n = sc.nextInt();
if(n%7 == 0 || n % 10 == 7)
System.out.print(n + " is a Buzz number");
else
System.out.print(n + " is not a Buzz number");
}
else
{
System.out.print("Enter a number: ");
int a = sc.nextInt();
int b = sc.nextInt();
  
if((a+2 == b || b+2 == a) && a%2 == 1)
System.out.print(a + " and " + b + " are consecutive odd numbers");
else
System.out.print(a + " and " + b + " are not consecutive odd numbers");
}
}
}
}
