Java object casting

In Java, we can cast both reference and primitive data types . By using casting, data can not be changed but only the data type is changed. Note: type casting is not possible for a Boolean data type. There are 13 types of conversion in Java.

In Java, type casting is a method or process that converts a data type into another data type in both ways manually and automatically . The automatic conversion is done by the compiler and manual conversion performed by the programmer.

Subtype polymorphism: Upcasting and late binding. Subtype polymorphism relies on upcasting and late binding. Upcasting is a form of casting where you cast up the inheritance hierarchy from a subtype to a supertype . No cast operator is involved because the subtype is a specialization of the supertype.

Casting acts on the compile time type, polymorphism on the runtime type .9 Eyl 2007
