메뉴만들기

메뉴의 구성은

 

메뉴바	java.awt.MenuBar
메뉴	java.awt.Menu
메뉴 아이템	java.awt.MenuItem

로 객체 모델링 되어 있다.

1. 메뉴 작성 순서

1) 메뉴를 올려놓을 메뉴바 클래스 객체 생성

 

MenuBar mb=new MenuBar(); setMenubar(mb) ; //Frame에 메뉴바가 붙는다.

2) 필요한 메뉴 클래스 객체 생성

 

Menu m=new Menu("Menu 이름"); mb.add(m);

3) 메뉴에 메뉴 아이템 추가

 

MenuItem item=MenuItem("Item 이름"); m.add(item);

2. 사용예
