3) Up and Down

What if you want to move but not draw a line? That is as easy as calling bob.up(). This tells the turtle to pick up its tail so it doesn't draw on the screen. When you are done and ready to draw some more just call bob.down().

/*If you don't know what a for loop is yet this is equivalent to repeating the middle 4 lines 5 times in a row.*/

Turtle bob = new Turtle();

for(int i=0;i<5;i++)

{

bob.forward(20);

bob.up();

bob.forward(20);

bob.down();

}
