scope...

[Leandro Oliveira]

There is something that is not very clear to me, Java language especification says that in 6.3.1 Shadowing Declarations, that you can have a class variable named X, and a local variable with the same name!!! why the following is not compiling???

public class pac {
public pac() {
int e=2;
try{
System.in.read();
}catch(Exception e){}
}
}

what is the problem??? e (exception not the integer) has only the try/cathc scope isn't it???

From JavaDoc:

469 - 'variable' is already definedA local variable cannot shadow another local variable with the same name in an enclosing scope.

'e' in this case is not a class variable. It's a local variable.
Hope this helps,
