Ans. 
To avoid method overriding, make the method final or private.

• Declare the method as private to hide it from subclasses.

• Use the @Override annotation to ensure that a method is actually overriding a superclass method.

Q2. What is the 'finalize' keyword for?
Ans. 
The 'finalize' keyword is used in Java to perform cleanup operations before an object is garbage collected.
• The 'finalize' method is called by the garbage collector before reclaiming an object's memory.

• It can be used to release resources like closing files or sockets.

• It is not recommended to rely on 'finalize' for resource cleanup as it is not guaranteed to be called.
