    Default ToString

    Can anyone help solve my problem? Don't know where I've gone wrong.

    Main
    // Main
    public class Nicky {	
    	public static void main(String[] args)
    	{
    		func f = new func("Did it work? Hehehe", 10);
     
    		System.out.print(f());
    	}
    }

    Other class
    // functions
    public class func {
     
    	private String TheWord;
    	private final int TheNumber;
     
    	public func(String s, final int f)
    	{
    		TheWord = s;
    		TheNumber = f;
    	}
     
    	public String toString()
    	{
    		return String.format("The word is %s\nThe number is %d", TheWord, TheNumber);
    	}
    }

    And thanks for the help on the other post, should I report solve on there?

    EDIT:

    Oops, I apologize, here's the error:

    Exception in thread "main" java.lang.Error: Unresolved compilation problem:
    The method f() is undefined for the type Nicky

    at Nicky.main(Nicky.java:7)

    The compiler doesn't know what 'f()' is. I believe you meant to cause the object 'f' to print by way of its toString() method, in which case you'd simply print 'f', not 'f()'.

    Ha, I guess I didn't see that. I'll refrain from making useless post before looking more next time, sorry.

    There's no such thing as a "useless post" in theory. Everyone get's a programmers block now and then.
    Of course, everyone else wants to help you - which makes being a part of the forum even more important.

    Echoing Ada's comment, and hoping I didn't give you the impression there was anything useless about your post, a second set of eyes often see a simple error that we're unable to see ourselves for many reasons. While you're encouraged to figure things out on your own, don't hesitate to ask when you need help.
