Casting means converting values from one data type to
other data type.For example to convert the int values to
float type vlaues.

Types of casting:
1. Downcasting -source is larger than destination type
2. upcasting - Source is smaller than destination type.

casting can be applicable to both primitive type and Object
type.

primitive type - convert numeral to floating point and vice
versa.
Object type - converting from subclass to super class or
vice versa.
superClassObj = subClassObj;
