Final once again

[padmini Babu]

Dear friends,
There are 2 classes � class x1 AND class checkfinal � Please notice the differences.
And help me out.
class A
{
public static void main(String[] args)
{ final int a = 20;
System.out.println("Hello World!");
}
}
class B
{
};
class X1 extends A
{
public static void main(String[] args)
{
//A a = new A();//line 1
int a = 15;
System.out.println("Hello !");
}
};
DOUBT: This compiles. But if you put A a = new A()at line 1 , ie , instantiate A inside X1 then threre is a compile error �a is already defined in this method.� -- why
-------
class checkfinal
{
public static void main(String[] args)
{
B b = new B();
b.call();

System.out.println("Hello World!");
}
}
class A
{
final int i = 10;
};
class B extends A // {
A a = new A();// LINE --- 1
int i = 20;
void call()
{
for (;i==20 ; )
{
//
}
}


};
DOUBT: HERE IT IS THE SAME THING BUT IT COMPILES . EVEN IF I PUT A a = new A() , the code compiles. why?

Thanks in advance

This has nothing to do with final. It only has to do with your choice of variable names.
In the first case you have two variables both named "a". This causes a problem for the compiler - so it complains. In the second case you have politely converted the variable name to "i" and eliminated the problem.
