What is the process of inlining and how is it accomplished in Java?

What will be an ideal response?

Because a final method's definition can never change-that is, can never be overridden with a modified version-the compiler can optimize a program's performance by removing the calls to final methods and replacing them with the expanded code of their definitions at each method call location. This process is called inlining the code. You are never aware that inlining is taking place; the compiler chooses to use this procedure to save the overhead of calling a method, and this makes the program run faster. The compiler chooses to inline a final method only if it is a small method that contains just one or two lines of code.
