Finch robot. Java

Question

I am currently using loops with the finch robot to test some java codes and have come across an error. Here is my code.

import edu.cmu.ri.createlab.terk.robot.finch.Finch;

public class CS1702_Lab4 {
    public static void main (String[] args) throws Exception
    {
        Finch myf = new Finch();

        myf.setWheelVelocities(100,100);
        long before = System.currentTimeMillis();{
        while(System.currentTimeMillis() - before < 5000)
        {
            Thread.sleep(500);
            if (myf.isTapped()) break;

        }
        myf.stopWheels();
        myf.quit();
    }
}

On line "myf.setWheelVelocities(100,100)", I am getting the following error;

• Syntax error on tokens, delete these tokens -Syntax error on token(s), misplaced construct(s).

Any help towards solving this error is appreciated. Many thanks.

Answer 1

It might be too late now, but this piece of code

myf.setWheelVelocities(100,100); 

should have 3 sets of numbers e.g.

myf.setWheelVelocities(100,100,5000);  

Answer 2

you have too many brackets { }

remove them in these lines:

long before = System.currentTimeMillis();{

and here:

myf.quit();
 }

Also it seems as if you have no class declaration.

public class CS1702_Lab4 {
  public static void main (String[] args) throws Exception
  {
       Finch myf = new Finch();

       myf.setWheelVelocities(100,100);
       long before = System.currentTimeMillis();

       while(System.currentTimeMillis() - before < 5000)
       {
          Thread.sleep(500);
          if (myf.isTapped()) break;

       }
       myf.stopWheels();
       myf.quit();
  }
}
