Java Interface and Abstract Class Example Code || Abstract class vs Interface in Java Example

java interface vs abstract class example code download tutorial example What are the difference between interface and abstract class in Java all explain in the following Example code in java


public interface Moveable {
 
    int AVG_SPEED=40;
 
    void move();
 
    void speedUp(int increment);

    void applyBrakes(int decrement);
}

 abstract class Vehicle { 

    String Name;

    int RegNo;

    Vehicle(String nm,int rn){

        this.Name=nm;

        this.RegNo=rn;

    }

    public void DisplayInfo() {  

        System.out.println("Vehicle Name : "+this.Name);

        System.out.println("Vehicle Reg No : "+this.RegNo);

    }

    public abstract  void start();

} 

public class Car extends Vehicle implements Moveable{

    float speed;

    Car(String nm,int rn){

        super(nm,rn);

       

    }

    @Override

    public void speedUp(int increment) {

        this.speed+=increment;

        System.out.println("Speed Up Car");

        System.out.println("Current Speed:"+speed);

    }

    @Override

    public void applyBrakes(int decrement) {

        this.speed-=decrement;

        System.out.println("Apply Brake in Car");

        System.out.println("Current Speed:"+speed);

     }

    

    @Override

    public void move() {

         this.speed=AVG_SPEED;

         System.out.println("Current Speed:"+speed);

    }

    @Override

    public void start() {

        this.speed=0;

    }

   

   

}
