formatting text via a class
Aug 20th, 2009, 2:36pm  
Hi, I have a class that aligns text to the right margin. I'd like to pass a string to it and have it return the formatted string. Then, in the main part of the program, I'd use the text() function to draw to the screen.

I never really understood how to get information back from a class. Do I include return in there somewhere? How do I access this returned information in the main program?

Classes don't return values. Methods do.

Code:
class Foo {
  void a() {
    // this method doesn't return anything (void)
  }
  int b() {
    // this method returns an integer (int)
    return 12;
  }
}


Just call the method on your object :

Code:
Foo myObject;
println(myObject.b());
