Method Overloading in Java In Java, Method Overloading allows us to define multiple methods with the same name but different parameters within a class. This difference can be in the number of parameters, the types of parameters, or the order of those parameters. Method overloading in Java is also known as Compile-time Polymorphism, Static Polymorphism, or Early binding, because the decision about which method to call is made at compile time. When there are overloaded methods that accept both a parent type and a child type, and the provided argument could match either one, Java prefers the method that takes the more specific (child) type. This is because it offers a more better match. Key features of Method Overloading: Multiple methods can share the same name in a class when their parameter lists are different. Overloading is a way to increase flexibility and improve the readability of code. Overloading does not depend on the return type of the method, two methods cannot be overloaded by just changing the return type. Different Ways of Method Overloading in Java The different ways of method overloading in Java are listed below: Changing the Number of Parameters. Changing Data Types of the Arguments. Changing the Order of the Parameters of Methods Advantages of Method Overloading The advantages of method overlaoding is listed below: Method overloading improves the Readability and reusability of the program. Method overloading reduces the complexity of the program. Using method overloading, programmers can perform a task efficiently and effectively.  Using method overloading, it is possible to access methods performing related functions with slightly different arguments and types. Objects of a class can also be initialized in different ways using the constructors. Disadvantages of Method Overloading Too many overloaded methods can make the code harder to read and maintain. Similar method names with different parameters can confuse developers and lead to incorrect usage. Improper use may lead to ambiguity in method selection, especially with type conversions.
