with the for loop it does not compile, without it it does.
Java:

public class Threads1
{
    public static void main(String[] args)
    {
               
        City city = new City();
                SmarterRobot karel = new SmarterRobot(city, 2, 0, Directions.EAST, 4);
                CityFrame frame = new CityFrame(city);
       
                Walls.makeWall(1, 4, 3, city , "WEST");
        Walls.makeWall(1, 4, 3, city , "NORTH");
       
        for(int fourTimes = 0; int fourTimes < 4; fourTimes++)
        {
          karel.putThing();
          karel.move(3);
          karel.turnRight();
        }
       
       
    }
}

you're redeclaring fourTimes. Just remove the int infront of the second fourTimes and it should work.

code:
karel.putThing();
karel.move(3);
karel.turnRight();


This really looks like something that might be a good candidate for refactoring out into a method in a suclass of the SmarterRobot class.
