Well i got this code off the Internet and want to make it do some other stuff, but it doesn't work atm. here the code
// FILE: MovePanel.java
//
// The display panel for a key events program -- arrow keys are used
// to move a stick figure around, the g key is used to make the figure
// grow by 50% (increase in height by 50%), the s key causes the
// figure to shrink (to half its size)

// the following give the initial parameters for the figure

it says that the error is "line 14 of the MovePanel.java it exspected a '.' "
