Problem with annotation [message #164548]

Hi,
When i am trying to compile the following code in eclipse 3.2 it gives me
an error

class parent
{
public static void call()
{
System.out.println("I am parent");
}
}

class Child extends parent
{
@Override public static void call()
{
System.out.println("I am child");
}
}

Whereas, when i compile the same code using eclipse 3.1.2 it compiles
fine. what's the problem?

Which error? Did you switch to 1.5 compliance?

The error was

"The method call() of type Child must override a superclass method"

Yes, i did set my project compliance level as 5.0. When i remove the
@Override annotation it complies fine. Can ne1 pls help in this regard.

I think with static methods, this is called Hiding, not Overriding.

http://java.sun.com/docs/books/jls/third_edition/html/classe s.html#8.4.8.2

Eclipse seems to behave correctly then.

Thnx that helped.

If you compile the code using the javac at command prompt the code
compiles, while it is not compiling with eclipse 3.2. Even, the same piece
of code compiled in eclipse 3.1.2.
