[Solved]Create Java Class Create Java Class File Read Write Outcome Come Word Nice Weather Read Ni Q37256568

create java class

create java class // there is no file to read and write so theoutcome should come out as this
word: Nice weather
read: Nice weather

I have to include these
class Stream {
private String buffer;
//create code
}
public String read() {
//create code
}
public void write(String s) {
// create code
}
}

here is my code

class File {
public String content;
}
class Reader extends Stream {
private File ff;
public Reader(File h) {
ff = h;
}
class Writer extends Stream {
private File ff;
public Writer(File h) {
ff = h;
}
class Main {
public static void main(String[] args) {
File ff = new File();
       Writer writer = newWriter(ff);
       Reader reader = newReader(ff);
       writer.write(“Nice weather”);
       String msg = reader.read();
       System.out.println(” word:” +ff.msg);
       System.out.println(” read:” +msg);
}
}

///////////////////////////////////////////////////////additionalqueeestion!

also I need to fix this code there is a minor mistake and Icouldn’t find it

outcome should be this

30 50

Mz’s current speed: 30

Gs’s current speed: 50

and this is my code

class Motor {
   private int speed;
   public Motor(int speed) {
       this.speed = speed;
   }
   public int getSpeed() {
       return this.speed;
   }
   public void speedUp(int speed) {
       this.speed += speed;
   }
   public void speedDown(int speed) {
       this.speed -= speed;
       if (this.speed < 0)
           this.speed =0;
   }
}

class Car {
   Motor motor;
   private String name;
   private int highSpeed;
  
   public Car(Motor m, String name, int range) {
       this.motor = m;
       this.name = name;
       this.highSpeed = range;
   }
   public void speedUp(int speed) {
       if (motor.getSpeed() + speed >highSpeed)
          System.out.println(“Can’t accelerate!”);
       else
          motor.speedUp(speed);
   }
   public String toString() {
       return name + “‘s current speed : “+ motor.getSpeed();
   }
}

class Main {
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
       Motor m = new Motor(0);
       Car oldCar = new Car(m, “Mz”,100);
       Car newCar = new Car(m, “Gs”,200);

      oldCar.speedUp(keyboard.nextInt());
      newCar.speedUp(keyboard.nextInt());
       System.out.println(oldCar);
       System.out.println(newCar);
       keyboard.close();
}
}
