public class Main {

public static void main(String[] args) {

// polymorphism = greek word for poly-"many", morph-"form"
ability of an object to identify as more than one type

Car car = new Car();
Bicycle bicycle = new Bicycle();
Boat boat = new Boat();

Vehicle[] racers = {car, bicycle, boat};

for(Vehicle x : racers) {
x.go();
}

}
}

public class Vehicle {

public void go() {
// TODO Auto-generated method stub

}
}

public class Car extends Vehicle{


@Override
public void go() {
System.out.println("*The car begins moving*");
}
}

public class Bicycle extends Vehicle{


@Override
public void go() {
System.out.println("*The bicycle begins moving*");
}
}

public class Boat extends Vehicle{


@Override
public void go() {
System.out.println("*The boat begins moving*");
}
}

I had struggled with figuring out what polymorphism is for weeks
But with just watching this video
I feel the power in my hands, everything is so clear now
I extremely respect what you did

my classmates and my batchmates kept on asking me how come i already know all the topics our professor taught.. i told them i binged watch youtube tutorial on your channel and ask them favor subscribe, like and comment . so you'll make more videos for us... we learned so much from you more than what is taught in our school we so much appreciate your efforts bro..🥰🥰🥰

another way is to use instanceof inside the for loop, we each time check :
if ( x instanceof Car ) x.go();
if ( x instanceof Bicycle ) x.go();
if ( x instanceof Boat ) x.go();
In case someone don't want to redefine the method go in superclass
