Question

I know how to overload a method, and how to override a method. But is that possible to overload AND override a method at the same time? If yes, please give an example.

Answer 1

Overloading and overriding are complementary things, overloading means the same method name but different parameters, and overriding means the same method name in a subclass with the same parameters. So its not possible for overloading and overriding to happen at the same time because overloading implies different parameters.

Examples:

class A {
    public void doSth() { /// }
}

class B extends A {
    public void doSth() { /* method overriden */ }

    public void doSth(String b) { /* method overloaded */ }

}

Cheers!
