Best way to create JFrame [closed]

Question

Which is the best way to create a JFrame and handle it?

1. Create a class and inside it create an object JFrame
2. Inherit from JFrame like class MyClass extends JFrame

Answer 1

Whenever possible, do not use inheritance (your class is-a JFrame) but choose composition (e.g. your class has-a JFrame). It's a common design principle.

And it doesn't have any significant impact on performance.

Answer 2

Basically, the only times you should extend JFrame is if you need to overload any methods in it.

That being said, there shouldn't be any noticeable performance hit one way or the other.
