Java Example - Method Overloading

Java Examples

First, let's look at the definition of method overloading: If two methods have the same name but different parameters, then one method is considered an overload of the other. Here is the specific explanation:

The method names are the same
The parameter types and the number of parameters are different
The return types of the methods can be different
The modifiers of the methods can be different
The main method can also be overloaded

The following example demonstrates how to overload the info method of the MyClass class:

MainClass.java File

class MyClass {
    int height;
    MyClass() {
        System.out.println("No-argument constructor");
        height = 4;
    }
    MyClass(int i) {
        System.out.println("House height is " + i + " meters");
        height = i;
    }
    void info() {
        System.out.println("House height is " + height + " meters");
    }
    void info(String s) {
        System.out.println(s + ": House height is " + height + " meters");
    }
}
public class MainClass {
    public static void main(String[] args) {
        MyClass t = new MyClass(3);
        t.info();
        t.info("Overloaded method");
        // Overloaded constructor
        new MyClass();
    }
}

The output of the above code is:

House height is 3 meters
House height is 3 meters
Overloaded method: House height is 3 meters
No-argument constructor
