In this video, we delve into the concept of method overloading, a powerful feature of object-oriented programming in Java. By the end of this tutorial, you'll have a solid understanding of method overloading and how to implement it in your Java programs.
This tutorial will equip you with the knowledge and skills to leverage method overloading effectively in your projects.
Method overloading in Java means having two or more methods (or functions) in a class with the same name and different arguments (or parameters). It can be with a different number of arguments or different data types of arguments
🔵 Following topics are covered in this session:
00:00 - Introduction
00:32 - What is Method Overloading in Java?
02:08 - Examples and Implementation of VS Code
09:07 - Advantages of Method Overloading
In this lecture we will learn:
✅ Parameters of a method
✅ Method overloading in Java
✅ When does method overloading happen?
✅ Different ways of method overloading in Java
#1
A class doesn't need to have methods and variables. It will be empty also.
- The parameters that except the values in a method should be equal to the parameters that we pass in a method to call it.
- It might create a problem if the parameters excepted by the method are not equal to the number of values passed.
- So, to overcome this problem we do overloading.
- Either the number of parameters or the type of parameters should be different.
#2
Method overloading:- In Java, there can be more than one method with the same name but the number of parameters or type of parameters should be different.
- Method overloading is also known as Compile-time Polymorphism, Static Polymorphism, or Early binding in Java.
- In Method overloading compared to parent argument, child argument will get the highest priority.
#3
Different ways of Method Overloading in Java:-
1. Changing the number of parameters
- Method overloading can be achieved by changing the number of parameters while passing to different methods.
2. Changing Data Types of the Arguments
- If methods have the same name but have different parameter types then also methods are considered as overloaded.
3. Changing the Order of the Parameters of Methods
- By rearranging the parameters of two or more overloaded methods.
