Java Method Overloading

In Java, method overloading allows a class to have multiple methods with the same name but different parameters. Here's a concise overview:

Definition:

• Method overloading is a feature that allows a class to have multiple methods with the same name but different parameter lists.

Parameters:

• Methods must have different parameter lists, which can include different data types, different numbers of parameters, or both.

Return Type:

• The return type of the methods can be the same or different.

Example:

• Example of method overloading:

int add(int num1, int num2) {
    return num1 + num2;
}

double add(double num1, double num2) {
    return num1 + num2;
}

Calling Overloaded Methods:

• The Java compiler determines which method to call based on the number and type of arguments passed during the method invocation.

Benefits:

• Provides a way to create methods that perform similar tasks but operate on different types of data.
• Enhances code readability and reduces method naming complexity.

Summary

Method overloading allows for cleaner and more intuitive code by providing multiple ways to call a method with different argument types. Understanding how to use method overloading effectively is essential for creating flexible and expressive Java programs.
