//===========================================================================//
  본 내용은 2002년 제가 Java 강의를 수강하며 정리 했던 내용을
    기본으로 하여 정리하였습니다.
  - 마침 java 기초를 전파할 기회가 생겨 핑계김에 정리해 가려 합니다.

1. awt 와 Swing 의 비교
                          awt                       swing
    사용시작버젼         1.1미만                   1.2이상
    import               java.awt                  java.awt(Layout Manager 때문에 필요)
                         java.awt.event            java.awt.event
                                                   javax.swing
                                                   javax.swing.border
                                                   javax.swing.event
                                                   javax.swing.tree     //탐색기의 트리형식을 이용할 수 있다
                                                   javax.swing.table    //엑셀같은 형태를 이용할 수 있다

    특징                 platform 종속적           platform 독립적
                         중량 Component            경량 Component      //시스템이 바뀔 경우 이동이 쉽다.
