User comments below. All of them might not be correct.

Ans is we have the final keyword which is used to make the variable value fixed through out the program...
* if we make variable than we cant change value of that variable through out the program
* if we make a method as final than we can t override that method in the Child classes
* if we make a class as final than no other class cant extend that class(String,Math)

here we are creating the instance for the Final class than memory will allocate for the instance variable assign than initialized to 35  and in constructor we are creating assign local variable with 10 calling print so it will print the main we have the 2 local variables res and assign assign is assgned with the 30 and result is assigned with the 20 next we are calling the print() by passing   result so there it will print we are passing result to process this will return by adding 5 so it will print 25  next we are printing the assign which is 30 next we are passing f.assign which is 35
