Java Tutorial : Java method overloading vs method overriding(version2)

MethodOverridingExample.java

class Animal
{
    public void eat()
    {
        System.out.println("Animal is eating...");
    }
}

class Lion extends Animal
{
    public void eat()
    {
        System.out.println("Lion is Eating meat...");
    }
}

public class MethodOverridingExample
{
    public static void main(String args[])
    {
        Animal animalRef = new Lion();
        animalRef.eat();
    }
}

Output

Lion is Eating meat...

OverloadingExample.java

public class OverloadingExample
{

    public void add(int a, int b)
    {
        int total = a + b;
        System.out.println("total : " + total);
    }

    public void add(int a, int b, int c)
    {
        int total = a + b + c;
        System.out.println("total : " + total);
    }
    
    public static void main(String args[])
    {
        OverloadingExample overloadingExample= new OverloadingExample();
        
        //Call two parameter add method
        overloadingExample.add(2,2);
        //Call three parameter add method
        overloadingExample.add(5, 5, 5);        
    }

}
