Two rules apply to overloaded methods: 1. The return type of the methods can be different, but the argument lists of overloaded methods must differ. 2. The argument lists of the calling statement must differ enough to allow unambiguous determination of the proper method to call.

Is it possible to override overloaded methods why?
Yes. Overloaded methods are also Java methods and all Java methods can be overridden.
What are duplicate java method names?
overloaded methods.
Can you override method in the same class?
You cannot override a method inside the same class. If you do that, it is called Overloading. Experienced java programmers can clearly identify the difference between overloaded methods and the overridden ones. We just had a detailed look at overridden methods and it is time to take a look at the overloaded ones. Overloaded methods let you reuse the same method name in a class, but with different arguments (and optionally, a different return type). Overloading a method often means you're being a little nicer to those who call your methods, because your code takes on the burden of coping with different argument types rather than forcing the caller to do conversions prior to invoking your method. The rules are simple: • Overloaded methods MUST change the argument list. • Overloaded methods CAN change the return type. • Overloaded methods CAN change the access modifier. • Overloaded methods CAN declare new or broader checked exceptions. • A method can be overloaded in the same class or in a subclass. In other words, if class A defines a doStuff(int i) method, the subclass B could define a doStuff(String s) method without overriding the superclass version that takes an int. So two methods with the same name but in different classes can still be considered overloaded, if the subclass inherits one version of the method and then declares another overloaded version in its class definition.
Method overloading in java?
No.In C++, you can overload both methods, and existing operators - although you can't invent new operators.In Java, many things that might cause confusion were eliminated; one of these is operator overloading. However, you can still overload methods, and this is sometimes very useful.
When will overloading happens?

So two methods with the same name but in different classes can still be considered overloaded, if the subclass inherits one version of the method and then declares another overloaded version in its class definition. Let us say we have the Ferrari class with a method drive() as below: Public class Ferrari extends Car { Public void drive() {…} } Below are the legal overload method declarations: 1. public void drive(String destination, String roadToTake) {…} 2. public void drive(String destination, int timeToTake) {…} 3. public void drive(String destination) throws RouteNotFoundException {…} Assuming that the Ferrari class has the above 3 methods, below are is an illegal overload: 1. public String drive (String destination, String roadToTake) {…} - You cannot have two methods which differ just in the return type. This is not allowed

Can a main method in java be overloaded?
Yes. The main method is just like any other java method and can be overloaded. But - Only the method with public static void main(String[] args) signature will get invoked when the class is run.
What rules that apply when communicating over computer?
Such rules are called "protocols".
What are three rules that apply to diffusion?
No.

How can two methods have the same signature?
Two methods can have the same signature when you override a method. A superclass calledrectangle might have a method called draw(). Then you make a subclass called squareand give it a method called draw() also. When you call the draw() method from square, it overrides the draw() method in rectangle. Note this is different than overloading, where you have two methods with the same name but different signatures, like draw() and draw(Color c).
An instance method or constructor may be overloaded by providing the same name and arrgument list?
You can overload instance methods and constructors (ref. Prog. Logic)
