A "native" method invokes a non-Java implementation, and therefore requires no braces. A native library is loaded via System.loadLibrary() and must be available to the JVM at runtime. Use of native methods generally makes the program platform-specific.

And that's about as much as you need to know about "native" for the SCJP. Does that clear it up?

But here the method is defined as final so can we still define the method some were else

A final method cannot be overridden.

An abstract method defers implementation to a subclass, so an abstract method cannot be final.

But a native method is not abstract. Instead of deferring implementation to a subclass, a native method goes elsewhere (a native library) for its implementation.

Yes thats true.
The only thing u shud remeber is being native means we are providing the alternate implementation and else is immmaterial.
Assume some thing like this if the method implementation is provided the remaining signature public static final void is legal declaration..

Correct me if i am wrong
