Casting may be required to distinguish the method to call in the case of overloading:
|
||
|
|
----
|
||
|
|
class A {}
|
||
|
|
class B extends A{}
|
||
|
|
class C {
|
||
|
|
void fun(A a){}
|
||
|
|
void fun(B b){}
|
||
|
|
|
||
|
|
void foo() {
|
||
|
|
B b = new B();
|
||
|
|
fun(b);
|
||
|
|
fun((A) b); //call the first method so cast is not redundant.
|
||
|
|
}
