예제를 계속 따라하고 있는 초보입니다.
그런데, 181쪽 예제는 아무리 봐도 똑같이 했는데 이런 메세지가 나오는 군요
글구 저와 같은 질문은 찾아봐도 잘 보이지가 않아서요
WindowEvent.java:3: class WindowEventTest must be declared abstract. it does not define void windowDeiconified(java.awt.event.WindowEvent) from interface java.awt.event.WindowListener.
public class WindowEventTest extends Frame
^
WindowEventTest.java:13: class WindowEvenTtest is an abstract class it can't be instantiated.
new WindowEventTest();
^
