 +====== 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>
