Not sure if this question is Java-specific or not, but in the following example code...

class Ball {
    ...
}

Ball newball=new Ball();
anotherVariable=newball;

Does anotherVariable just point to newball? Does it duplicate it?

Try this, and you tell me:

(Toggle Plain Text)

public class Test {

    public Test() {
    }
  
    public static void main(String[] args) {
        Test c = new Test();
        Test d = c;
        System.out.println(c);
        System.out.println(d);
    }   
}

It only points to the original.

Just for future reference you should NOT use newwhatever for an object name because it might get confused the reserved word in java 'new'.

No it won't, and for the same reason I could have a variable called "for1" or "if2".

I think what he meant is that it would get confused by people, not the compiler. And I agree; I realized that after I typed it in--If that were actual code, I'd have changed that name.

Ohhhh, okay. I've been thinking about code too much recently
