Method overloading in Java is a feature that allows a class to have multiple methods with the same name but different parameters. This means that a class can have multiple methods with the same name but different argument lists. When a method is invoked, the compiler decides whic

Method overloading is beneficial in several ways. First, it makes the code more readable and easier to understand. Instead of creating a new method with a different name for each set of parameters, developers can create methods with the same name, making it easier to find and understand the code. Second, it saves developers time and effort by reducing the amount of code they need to write. Finally, it makes the code more flexible and adaptable to changes, as new methods with different parameters can be added without changing the existing code.
Let’s take a look at an example of method overloading in Java:
public class Calculator {
public int add(int a, int b) {
return a + b;
}
public double add(double a, double b) {
return a + b;
}
public int add(int a, int b, int c) {
return a + b + c;
}
}
In this example, we have a class called Calculator with three methods called add(). Each of these methods has the same name, but a different parameter list. The first method takes two int parameters and returns an int. The second method takes two double parameters and returns a double. The third method takes three int parameters and returns an int.
When we call the add() method, Java will determine which method to call based on the parameters passed to it. For example, if we call add(2, 3), Java will call the first method, as it takes two int parameters. If we call add(2.0, 3.0), Java will call the second method, as it takes two double parameters. And if we call add(2, 3, 4), Java will call the third method, as it takes three int parameters.
In conclusion, method overloading is a powerful feature in Java that allows developers to create multiple methods with the same name but different parameter lists. This makes the code more readable, saves time and effort, and makes the code more flexible and adaptable to changes.
