Answer 3

其实我的问题只有一个，如何实现　Player_Frame 和 full_Frame 实现通信？让Player_Frame 和Player_Frame　中的i实现同步化．．．目的是让全屏播放退出来以后，能让全屏退出的那张图片放在原来的框架上．（或下翻到第i张时，全屏的那张就从第i张开始全屏播放）．．．．
我也知道，也许没有人回答的，哎．

Answer 4

在full_Frame的监听键盘事件那边把当前图片反馈给Player_Frame

Answer 5

你这种情况需要使用继承，即编写一个基类 BaseFrame extends JFrame 将i和getfile等可重用的方法和成员变量定义为公有的或受保护的
public abstract class BaseFrame extends JFrame
{
    protected int i=1;
    protected String[] files=getFile();   public String[] getFile()
      {
              File f=new File("./src/image/");
              return f.list();
      }
   }然后full_frame 和player_frame 都可以继承于BaseFrame
另外，你的代码没有注释，同时命名规范不标准 类应该这样定义 FullFrame PlayerFrame 才标准

Answer 6

对于你的i需要同步，可以使用静态成员的方式来解决。
 protected static int i=1;
那么，当任何一个子类的实例更改了i值，其它实例能获取到最新的值

或者将一个窗体作为参数传入另一窗体.这个　－－－－－－－－＞将一个窗体作为参数传入另一窗体.
