Question

I have some Java code:

public class Car 
{ 
    private int yearModel;
    private String make;
    private int speed;

    public Car(int newYearModel, String newMake)
    {
        yearModel = newYearModel;
        make = newMake;
        speed = 0;
    }
    public int getSpeed()
    {
        return speed;
    }
    public void accelerate()
    {
        speed += 5; 
    }
}

I try to compile and run this specific program and I get this error:

CarClient.java:16: error: cannot find symbol
      myCar.accelerateSpeed(speed);
                          ^
  symbol:   variable speed
  location: class CarClient

What does error: cannot find symbol mean?

Answer 1

You’re calling accelerateSpeed(speed) but the only method you have implemented is accelerate() which takes no parameters. Similarly, you’re trying to call brakeSpeed(speed) but have only implemented brake() with no parameters. Either implement the functions you’re trying to call, or change the names of the functions you already have implemented.
