are we suppose to create junit testers for the home work or can we just make easier testers that just print the values. for example for E5.1 it would be much easier to just use scanner to print the sign of the number, I keep getting errors using junit but i know that the sign of 20 is positive, there is no need for a tester for that. or how can i make a junit test for it. only p5.2 requires a junit tester.

what exactly is the auxiliary method going to do. the main method already sets up what the input will be. positive, negative or zero.

i did it differently since i started on Wednesday before the new instructions were updated. this is what i have im just having problems creating a junit test.

public class E5_1
{
    private int integer;

    public E5_1(int integer)
    {
       this.integer = integer;
    }
    
    public int sign()
    {
        
        if(integer == 0 )
        {
            System.out.println("the number is zero");
        }
        if(integer < 0)
        {
            System.out.println("the number is negative");
        }
        else if (integer > 0)
        {
            System.out.println("the number is positive");
        }
        return integer;
    }
    }
