Java Method Overloading is a feature in Java that allows a class to have multiple methods with the same name but different parameters. This means that a class can have two or more methods with the same name, but with different arguments or parameter types. The Java compiler determines which method to call based on the number and types of arguments passed to the method.
Method overloading is a way to make code more readable and maintainable. It allows developers to use the same method name for different operations, which makes the code more intuitive and easier to understand. Method overloading is also useful when a method needs to perform similar operations on different types of data.
Here is an example of method overloading in Java:
public class Calculator {
public int add(int x, int y) {
return x y;
}
public double add(double x, double y) {
return x y;
}
}
In this example, the Calculator class has two methods with the same name, add(). However, one method takes two integers as parameters, while the other takes two doubles. When the add() method is called, the Java compiler determines which method to call based on the types of arguments passed to the method.
Here is an example of calling the add() method:
Calculator calculator = new Calculator();
int result1 = calculator.add(2, 3);
double result2 = calculator.add(2.5, 3.5);
In this example, the first call to the add() method passes two integers, so the add(int x, int y) method is called. The second call to the add() method passes two doubles, so the add(double x, double y) method is called.
Method overloading is a powerful feature in Java that allows developers to write more flexible and maintainable code. By using method overloading, developers can create methods with the same name that perform different operations on different types of data.
