Java Programming - Declarations and Access Control - Discussion

Can you explain it in detail?

Can any one explain ?

Please anyone explain it?

What is the working of synchronize and native?

Synchronize and native works because synch blocks the execution of other methods on the same class (for the duration of the method). Maybe the native method wants to modify a shared resource.

1. protected abstract void m1();
Is correct because abstract method may be implemented in subclass and protected allows it to do so.
2. static final void m1(){}
Is also correct because final does not allow method to be changed and static does not user to another method with same name.
3. synchronized public final void m1() {}
It allow only one instance of method to be executed at a time.
4. private native void m1();
It allows method written in another programming language to be executed in java

But as I can see the question is asked for declaration only and not the definition of function.

Shouldn't access specifiers like public, private and protected be the first words in a declaration statement? Please correct me if I'm wrong, I read this somewhere.

static final void m1(){}

Can anyone explain it clearly?

Why are {} specified in the declaration?
