Method not returning a value

[mathwiz7]

This should be a simple problem...I can't figure out what I'm doing wrong. I'm only trying to have a new method return the value I just typed but it doesn't seem to work. Here's what I have...

public static int promptForTrialNumber(int t)
    {
        System.out.print("How many darts/trials? ");
        Scanner in = new Scanner(System.in);
        t = in.nextInt();
        return t;
    }
    public static void main()
    {
        int trialNumber = 0;
        promptForTrialNumber(trialNumber);
        System.out.println(trialNumber);
         
    }

The code just prints out 0 instead of the number I had just typed...It's not an issue with the scanner as I inserted a println in the promptForTrialNumber method after the in.nextInt() and before the return statement and that returned the value typed.

You need to assign the value returned by your method to the variable. e.g.,

trialNumber = promptForTrialNumber();

and

    // get rid of the parameter
    public static int promptForTrialNumber()
    {
        System.out.print("How many darts/trials? ");
        Scanner in = new Scanner(System.in);
        int t = in.nextInt();
        return t;
    }

Note that Java is passes parameters by value always, so that passing your variable into the method won't work since it's a primitive variable. Even if it did work, it's a bad habit to get into since you'll be changing state by side effect rather than by assignment, making your code much harder to debug.
