Preventing Overriding in Java

By | February 25, 2011

Methods and variables can be ‘override’ in subclasses. (Yes, it’s a good

feature too!). But what if we don’t want to ‘override’ our Methods and Variables in Java?

It’s simple…

Declare them using the keyword ‘final’ as modifier. That’s it.


final int myVariable = 79;

So the value of myVariable can never be changed any way.

Also for Classes/Methods.


final class myClass{ whatever your code;} 

It will prevent our myClass being extended.
