    Default Homework assistance

    I'm just starting out at Java programming so my problem is likely obvious. The program needs to prompt the user to enter an integer and checks whether the number is divisible by 4, 5 and 6, or some combination of them, or just one of them. It then needs to tell the user what the number is and isn't divisible by. I think my problem is with a boolean but right now my program only tells the user if the number is divisible, not if it isn't.

    import java.util.Scanner;
     
    public class Unit3PartOne {
     
    public static void main(String[] args) {
     
     
    Scanner input = new Scanner(System.in);
    System.out.print("Enter an integer: ");
    int num1 = input.nextInt();
     
    if (num1 % 4 == 0 && num1 % 5 == 0 && num1 % 6 == 0)
    System.out.println("Your number is divisible by 4, 5, and 6");
     
     
    }
    }

    You need to make a list of all the tests to be done to solve the problem and then write the code for each one and test it.

    It looks like the code makes the same test two times????

    @pawan4angel If you have any ideas on how the OP should think through the problem and work towards a solution that would be good. Maybe a few short code samples to show some ideas with explanations of what they do and why they work. Like a mini-tutorial
