Hi There,



casting is required only for strongly typed languages like Java. They are not required for say, something like javascript, python, perl, etc.



You can download an excellent book at
http://64.78.49.204/ which will give detailed explanations on how casting is needed.



void bar() {

Object a = new String();

foo(A);

.

.

.
}



void foo(Object a){

String b = (String) a; // Example of casting an Object to String

.

.

.

}
