computer.java

有一个接口,用抽象类实现它的部分功能,再用实现类继承抽象类,实现其它没实现的接口方法

package cn.edu.csu.oo.abstractoper.interfaceoper;

public class Computer {

  /**
   * @param args
   */
  public static void main(String[] args) {
    MainBoard mainBoard = new MainBoard();
    NetCard netCard = new NetCard();
    mainBoard.userPCI(netCard);
    
    System.out.print("**********************" + "\r\n");
    SoundCard soundCard = new SoundCard();
    mainBoard.userPCI(soundCard);
    System.out.println(PCI.SIZE);
    
  }

}
