Which method is an example of an overloaded method?

Which method is an example of an overloaded method?

In Java, two or more methods may have the same name if they differ in parameters (different number of parameters, different types of parameters, or both). These methods are called overloaded methods and this feature is called method overloading. For example: void func() { }

How does method overloading work?

Method Overloading is a feature that allows a class to have more than one method having the same name, if their argument lists are different. It is similar to constructor overloading in Java, that allows a class to have more than one constructor having different argument lists.

What do you mean by overloading of methods?

Overloading allows different methods to have the same name, but different signatures where the signature can differ by the number of input parameters or type of input parameters or both. Overloading is related to compile-time (or static) polymorphism.

What is the purpose of constructor overloading?

If we want to have different ways of initializing an object using different number of parameters, then we must do constructor overloading as we do method overloading when we want different definitions of a method based on different parameters.

What do you need to know about method overloading?

The primary requirement for method overloading is that the methods share the same name. Their method signatures — the method name, the number of parameters, and the parameter data types — should otherwise be unique. In this way, the compiler can determine which method to execute.

What does it mean when method is overloaded in Java?

When this is the case, the methods are said to be overloaded, and the process is referred to as method overloading. The compiler will resolve the call to a correct method depending on the actual number and/or types of the passed parameters. The main advantage of method overloading increases the readability of the program.

Can a method be overloaded by changing only the return type?

Never consider that changing only the return type of the method, the method can be overloaded because the return type is not part of the method signature. Rule 3: The type of exceptions thrown from the methods are also not considered while overloading a method. The method overloading is not affected by the type of exceptions thrown by the methods.

What do you need to know about method overriding?

In method overriding, derived class provides the specific implementation of the method that is already provided by the base class or parent class. In method overriding, return type must be same or co-variant (return type may vary in same direction as the derived class).
