Quyida merosxo’rlikka misol keltiramiz. Bunda Bike (velosiped) classi super class, MountainBike (tog’ velosipedi) sub-class, Test classi dasturni ishga tushiruvchi main metodiga ega class.

class Bicycle {

public int gear;

public int speed;

public Bicycle(int gear, int speed)

{

this.gear = gear;

this.speed = speed;

}

public void brake(int decrement)

{

speed -= decrement;

}

public void increment(int increment)

{

speed += increment;

}

public String toString()

{

return ("Number of gears " + gears + "\n"

+ "Speed ​​" + speed);

}

}

class MountainBike extends Bicycle {

public int seatHeight;

public MountainBike(int gear, int speed,

int seatHeight)

{

super(gear, speed);

this.seatHeight = seatHeight;

}

public void seatSet(int seatHeight)

{

this.seatHeight = seatHeight;

}

@Override public String toString()

{

return (super.toString() + "\nSeat height "

+ seatHeight);

}

}

public class Test {

public static void main(String args[])

{

MountainBike mb = new MountainBike(3, 100, 25);

System.out.println(mb.toString());

}

}
