We can declare an inner class within the body of a method without naming it. These classes are known as anonymous inner classes
Very useful for controlled access to the innards of another class. and useful when we need one instance of a
special class.

The JVM is the core of the Java platform and is responsible for:
1. Loading bytecodes from the class files
2. Verifying the loaded byte codes
3. Linking the program with the necessary libraries
4. Memory Management by Garbage Collection
5. Managing calls between the program and the host environment

By using Adapter class we can implement the interface's required methods.
The Java AWT provides a number of adapter classes for the different EventListener interfaces. These adapter classes implements the corresponding interfaces with a series of do-nothing methods.
By subclassing the respective Adapter rather than implementing EventListener interfaces directly, one can
avoid having to write the methods that are not actually needed. Only those methods can be overridden that are planned to be actually implemented

Multitasking:heavyweight process and runs in a different address space so context switch or intercommunication between processes is much expensive.
Multithreading: light weight process and can run in a same address space so context switch or
intercommunication between processes is less expensive
