Best approach to define a Thread

There are 2 approached to define a Thread

1. By extending Thread class.
2. By implementing Runnable interface.

• Among the 2 ways of defining a Thread, implements Runnable approach is always recommended.

• In the 1st approach our class should always extends Thread class there is no chance of extending any other class hence we are missing the benefits of inheritance.

• But in the 2nd approach while implementing Runnable interface we can extend some other class also. Hence implements Runnable mechanism is recommended to define a Thread.

One approach to define a Thread(not recommended to use): 

Output:
main method
run method
      or
main method
run method
