final!

[kalyan v]

Hi,
To make a java class non subclassable (final class), we can use final. But any other ways to make a class final.

[Roy Ben Ami]

maybe making the class private too will work..
why do you need another way?

[Bosun Bello]

Only inner classes can be made private. Marking the class as final should suffice. The methods within the class will also be implicitly final.

kalyan,
If you were to make the constructor(s) unavailable, the class would then be un-subclassable.
Instances of the class could still be obtained through some static method.
A class based on the singleton pattern, might choose to make it's contructor(s) private, and then control the any instance creation of the class through a static method (often named getInstance).
