 ====== Your Initials in Beepers ======
-Draw your
+Have a robot with a name of you choosing draw spell out your initials using beepers. Make the initials at least 5 beepers high. Here is an example if your initials happen to be ''DRS'':

+Here is some starter code for a new class.  Feel free to rename the class or the robot.
+[[http://csis.pace.edu/%7Ebergin/KarelJava2ed/KJRdocs/index.html|API]] (Application Programming Interface)
+<code java>
+import kareltherobot.*;
+/**
+ *
+ * @author Your Name Here
+ * @version Aug 19, 2019
+ *  A Class with a main method to make your initials in beepers
+ *
+ */
+public class DrawInitials implements Directions
+{
+	public static void main(String[] args)
+	{
+		World.setDelay(30);
+		World.setSize(8,15);
+		World.setVisible();
+		task();
+	}
+	public static void task()
+	{
+		Robot lisa = new Robot(5, 1, South, infinity);
+		lisa.putBeeper();
+		lisa.move();
+		lisa.putBeeper();
+		lisa.move();
+		lisa.putBeeper();
+		lisa.move();
+		lisa.putBeeper();
+		lisa.move();
+		lisa.turnLeft();
+		lisa.putBeeper();
+		lisa.move();
+                lisa.putBeeper();
+		lisa.move();
+		lisa.putBeeper();
+		lisa.move();
+		lisa.turnOff();
+	}
+}
+</code>
+====== Making a method ======
+With all those ''move()'' and ''putBeeper()'' statements it is hard to read the code.  You can make  a method in your class called ''placeSomeBeepers'':<code java>/**
+	 * Places n beepers from Robot r ina striaght line
+	 * @param r the Robot placing the beepers
+	 * (precondtion: Robot must have enough beepers)
+	 * @param n the number of beepers to place
+	 */
+	public static void placeSomeBeepers(Robot r, int n)
+	{
+		for (int i=0; i < n; i++)
+		{
+			r.putBeeper();
+			r.move();
+		}
+	}</code>
+Now all your ''task()'' method can look like this:<code java>public static void task()
+	{
+		Robot lisa = new Robot(5, 1, South, infinity);
+		placeSomeBeepers(lisa, 4);
+		lisa.turnLeft();
+		placeSomeBeepers(lisa, 3);
+		lisa.move();
+		lisa.turnOff();
+	}</code>
