When you study object-oriented programming, you will come across several concepts like classes, objects, inheritance, java compiler online, interpreters, data abstraction and other useful concepts.
Among these concepts, the concept of polymorphism is quite interesting to learn. You can also study its subconcepts like method overloading and method overriding in Java.
When any given class has two or more methods with the same name but different parameters, it is called the mechanism of method overloading.
On the other hand, in the case of method overriding, the superclass and the subclass will have several methods with their sub names.
Both the fields too hold certain points of differences that every programmer should know.
To help you in this regard, we have prepared this blog where we are helping you study the concept of method overloading and overriding alongside their key differences.
Read on!
Method overloading in Java
The concept of method overloading is defined as the method when a class would have two or more method names. Though, their parameters can be quite different. At the time of their calling, it will be based on the respective method body which can easily be bonded.
In the case of overloading method in Java:
We will not be able to overload the return type
We may use the static method, the arguments or parameters can be bit different
We my not overload two methods at the same time
The main{} method can be overloaded in this case
Method overriding in Java
In case of method overriding in Java, the superclass and the subclass will generally have parameters with the same name. The JVM will call upon the function based on the respective method of objects that are used in the call function.
In thi case, when both the classes will contain the methods that have the same name or arguments as parameters, you can execute a program in an efficient way. If a child class will call the method, it will automatically override the required parent class.
This method is also helpful in doing the implementation of runtime polymorphism in Java language.
Difference between overloading and overriding methods in Java
Definition
Overloading
The method overloading in case of Java is helpful to allow the polymorphism on some arguments or argument types. This is also known as the related-time polymorphism. It can’t be easily overloaded. Static methods are quite easy to overload but their arguments can be different.
Method overriding
The method overriding in Java allows for the polymorphism in a java program. It is basically used when your parent class provides a suitable method to implement any other method for overriding it. When the two or more methods exist in the same class, they may have different types of parameters.
Usage
Method Overloading
The method overloading is basically used in a program to increase its readability and to improve on its different operations.
