====== Your Initials in Beepers ======
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>
