Need help with Object Casting

[Elaforestis]

Hey, i'm currently learning Casting and i have been having some difficulties!
I have 2 classes:
A superclass called Apple and a subclass called GreenApple:

GreenApple:

public class GreenApple extends Apple {
GreenApple a = new GreenApple();
Boolean greenColour;
a = a2;
a2 = (Apple) a;

GreenApple() {
	greenColour = true;
}
}

Apple:

public class Apple {
	public static void main(String[] args) {
		GreenApple appleColour = new GreenApple();
		System.out.println(appleColour.greenColour);
}
}

and i get the following compilation errors:

Exception in thread "main" java.lang.Error: Unresolved compilation problems:
Syntax error on token ";", { expected after this token
Syntax error on token "{", ; expected

at GreenApple.<init>(GreenApple.java:3)
at Apple.main(Apple.java:4)

whats wrong?

Still getting the same errors

I'm playing with your code right now too.
Yea its nothing with the semi-colon.
I'm gettin errors on lines 4 & 5 of the GreenApple class about identifiers....

What are you wanting a and a2 to do?

Remove lines #2, #4 and #5 from your GreenApple class; at least it will compile then. Never try to run anything when if didn't compile.

kind regards,

Thanks :P
I was just trying to experiment with object casting in order to further understand its usage.
