Turtle logo is an introduction to computer programming. We imagine that we are working with a turtle that is holding a pen — presumably in its mouth. As the turtle roams around its terrarium, it drags the pen, leaving tracks wherever it goes.
Sample Program
A simple example of a program to control a turtle might look something like this:
import org.gannacademy.cdf.turtlelogo.*;
public class DrawASquare{
public static void main(String[] args) {
Turtle cecil = new Turtle(); // instantiate a new turtle
// give the turtle some instructions
cecil.fd(100);
cecil.lt(90);
cecil.fd(100);
cecil.lt(90);
cecil.fd(100);
cecil.lt(90);
cecil.fd(100);
}
}
The output of this program would be:
