Question

Create an Airplane class (not abstract) that uses the Vehicle interface in Q1. The code for all methods should print simple messages to the screen using System.out.println(). Add an integer speed variable that is changed using the ChangeSpeed method. ChangeSpeed adds 5 to the speed each time it is called. Create a default constructor that sets the initial speed to 0. Don't create other constructors or any setter/getter methods.

PLEASE CODE THIS IN JAVA

Answer 1

//Airplane.java
public class Airplane implements Vehicle{

    int speed;

    public Airplane() {
        this.speed = 0;
    }

    public void Start() {
        System.out.println("Start method called");
    }

    public void Stop() {
        System.out.println("Stop method called");
    }

    public void ChangeSpeed() {
        speed += 5;
    }

    public int getSpeed() {
        return speed;
    }

    public void setSpeed(int speed) {
        this.speed = speed;
    }
}
