Question

In a file called DivisibilityTests.java, write a program that:

• Asks the user to enter an integer. It is OK for your program to crash when the user does not enter a valid integer.
• If the integer is less than 0, the program prints: "The number is negative."
• If the integer is divisible by 2 and by 3, the program prints: "The number is even and divisible by 3."
• If the integer is divisible by 2 but not by 3, the program prints "The number is even and not divisible by 3."
• If the integer is divisible by 3 but not by 2, the program prints "The number is odd and divisible by 3."
• If the integer is divisible by neither 2 nor 3, the program prints "The number is odd and not divisible by 3."

For example: if the user enters -5, your program output should look EXACTLY like this:

Please enter an integer: -5
The number is negative.

Answer 1

ANSWER:-

import java.util.*;

public class DivisibilityTests
{
   public static void main (String[] args)
   {
       Scanner sc=new Scanner(System.in);
       System.out.println("Please enter an integer : ");
       int n=sc.nextInt();
       if(n<0)
       System.out.println("The number is negative");
       else if(n%2==0 && n%3==0)
       System.out.println("The number is even and divisible by 3.");
       else if(n%2==0 && n%3!=0)
       System.out.println("The number is even and not divisible by 3.");
       else if(n%2!=0 && n%3==0)
       System.out.println("The number is odd and divisible by 3.");
       else if(n%2!=0 && n%3!=0)
       System.out.println("The number is odd and not divisible by 3.");
   }
}
