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”.
