Thanks for your replies - I had heard both stories but I was not sure how widespread they were

Try jGRASP - it's really easy to use.

And IMHO the best beginner Java book that I have ever used is Java Software Solutions - http://duke.csc.villanova.edu/jss1/index.html

I was wondering why IBM named this IDE "Eclipse" - does anyone know?

Thanks,

class Test{
public static void main(String args[]){
A a = (A) new Object(); //line 1
B b = (B) new A(); //line 2
}
}

class A{
}

class B extends A{
}

How come line 1 and 2 compile? We are performing a narrowing conversion.

Thanks.

Ah thanks soooooooooo much!!

Consider this program:
class ArrayObj{
public static void main (String[] args) {
String[] array = new String[5];
System.out.println(array[0]); //line 1
System.out.println(array[0].toString()); //line2-nullPointerException
}
}

Why does line 1 print null and line 2 generate an exception?
I was expecting line 1 to throw a nullPointerexception also, since I thought
toString() method would be called implicitly.

Thanks,
Cathy.

Thanks much!

Hi All,

I am running Java 1.5.0_04 on windows xp.

I have one animated GIF file and a static GIF file. First I setIcon() to the
JLabel with the static GIF file. Before I perform some activities, I
setIcon() to the JLabel with the animated GIF file so that the user knows
some kind of process is going on. The label gets updated with the animated gif, but the gif looks static, i.e. the animation is lost....why is this happening?

Hi all,

Is it possible to add a component to a specific cell using gridlayout?

I can get the border of a component by using comp.getBorder(), now what method should I use to determine the type of the border?
