Final Var ...

[Enamul Haque]

From the Java Tutorial I came to know about he final keyword and a example.......
final int aFinalVar = 3;
and it also says that a variable once called as final can't be initialized more that once. i.e. it's like const of C++.
Now my question is that can I change init it with other variables ofcourse once.
like:
int x = 20;
final int finalVar = x;

Yes, in fact since you can initialize your final vars in your constructors, they are often initialized with a parameter passed into the constructor.

public class MyClass {
    final int x;
    public MyClass(int x) {
        this.x = x;
    }
}
