Can someone explain to me SetFocusable(true) setFocusableTraversalKeysEnabled

Question

AddKeyListener(this);

Why do we use “this”

And what in the world does “setFocusable” mean

Answer 1

As u might be knowing that, this keyword refers to the current object, so whenever we pass this in parameters of addKeyListener(), it searches for the implementation of the KeyListener Interface metgods in the same class of which we will be making object...

Instead of this, you can also use the object of other classes which implements the KeyListener Interface..
