Hi Friends , can anyone resolve this Problem:


Java identifiers are case sensitive. identifier WELL is differ from Well. but i got a runtime exception while running this program: please tel me why its happened.

Well.java

class WELL
{
WELL()
{
System.out.println("WELL is invoked");
}
}

class Well
{
Well()
{
System.out.println("Well is invoked");
}
public static void main(String...as)
{

new Well();
new WELL();
}
}

I think you cant define same types(classes or interface) in the same package with same name.
As you declared both in one file class loader is having problem identifying the right one even if you will make Well class public.

Java is case sensitive, but your OS isn't. In Windows, you can't have two files named WELL.class and Well.class in the same folder.

The code you posted runs just fine under Linux.
