What are the implications of using functions in Java?
- We build upon familiarity with mathematical functions to introduce Java static methods, and then consider the implications of programming with func- tions, including libraries of functions and recursion. We stress the fundamental idea of dividing a program into components that can be independently debugged, maintained, and reused.

How are primitive types treated in Java?
- Java primitive types, however, are not treated in the same way as Java objects.Primitive types are assigned, compared, and passed as arguments using copysemantics, just as in C/C++. For example, i = j for two int variables i and jperforms a 32-bit integer copy. Assignment makes two variables refer to the same object. For example,
