The role of the Java final method

1. Do not want to let others modify the method implementation.

2. Use inline invocation when method calls.

3. A valid "off" dynamic binding so that the compiler can generate more efficient code for final method calls.

Java programming Idea: "However, in most cases, this does not make a difference to the overall performance of the program." So it's best to decide whether to use final based on the design, rather than using final "for the purpose of trying to raise performance."
