OverloadingTest.java

public class OverloadingTest
{

    public int add(int x, int y)
    {
        return x + y;
    }

    public int add(int x, int y, int z)
    {
        return x + y + z;
    }

    public int add(double x, int y)
    {
        return (int) x + y;
    }

    public int add(int x, double y)
    {
        return x + (int) y;
    }

    public static void main(String[] args)
    {
        OverloadingTest overloadingTest = new OverloadingTest();
        System.out.println(overloadingTest.add(4, 3));
        System.out.println(overloadingTest.add(2, 3, 4));
        System.out.println(overloadingTest.add(2.5, 3));
        System.out.println(overloadingTest.add(9, 3.4));

OverriddenTest.java

class Vehicle
{
    public void move()
    {
        System.out.println("Vehicles can move");
    }

}

class Car extends Vehicle
{
    public void move()
    {
        System.out.println("Car can move very fast");
    }

}

public class OverriddenTest
{

    public static void main(String[] args)
    {
        Vehicle vehicleRef = new Car();

        vehicleRef.move(); // prints Car can move very fast

        vehicleRef = new Vehicle();

        vehicleRef.move(); // prints Vehicles can move"
    }

}

Output

Car can move very fast
Vehicles can move
