学校の宿題がさっぱりわかりません (T_T)
JavaのAppletのチャプターを今やっています。

其の一
Assume that surfMessage references a Label with class-wide
scope that has already been added to the applet's container.
If surfCount is an int variable with class-wide scope and an
initial value of 0, code the methods needed to
(1) increment surfCount every time the user visits a different
Web page and (2) change the contents of surfMessage to display
"Surf count: n" (where n is the number of times they have visited
a different page) upon their return. NOTE: Prior to surfing,
surfMessage should display "Surf count: 0".

もう何をどうして良いのやら。。。 Start()とstop()を使うのでしょうか？
