Instead of defining two methods that should do the same thing, it is better to overload one. In the example below, we overload the plusMethod method to work for both int and double:

A method is a block of code which only runs when it is called. You can pass data, known as parameters, into a method. Methods are used to perform certain actions, and they are also known as functions. Why use methods? To reuse code: define the code once, and use it many times.
Method Overloading is applied in a program when objects are required to perform similar tasks but different input parameters. Every time an object calls a method, Java matches up to the method name first and then the number and type of parameters to decide what definitions to execute.
static double plusMethod(double x, double y) {. return x + y; } public static void main(String[] args) {. int myNum1 = plusMethod(8, 5); double myNum2 = plusMethod(4.3, 6.26); System.out.println("int: " + myNum1); System.out.println("double: " + myNum2); }
Java Method Overloading. 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:
4 paź 2024 · In Java, Method 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 a mixture of both. Method overloading in Java is also known as Compile-time Polymorphism, Static Polymorphism, or Early binding. In Method ...
8 sty 2024 · Method overloading is a powerful mechanism that allows us to define cohesive class APIs. To better understand why method overloading is such a valuable feature, let’s see a simple example. Suppose that we’ve written a naive utility class that implements different methods for multiplying two numbers, three numbers, and so on.
