Chapter 11.8, Problem 11.8.4CP

Program Plan Intro

Converting objects to primitive data types and vice versa:

• When one reference object can be typecast into other reference object. It is called as casting object.
• Objects and primitive datatypes are very different in Java. Converting objects to primitive data types and primitive datatypes to objects are not possible in any circumstance.
• The programmer can use “java.lang” package for converting primitive data types to objects and vice versa.
• Here most of the classes have same names as the datatypes and expect that the class names start with a capital letter like “Float” instead of “float”, “Short” instead of “short”.
• The two classes have different names corresponding to the datatypes: “Integer” instead of “int” and “Character” instead of “char”.
