如何将JFrame添加到我的程序中

Question

我已经创建了GUIPanel，但是我需要将它添加到我拥有的程序中;当我尝试从主类中运行其他程序时，GUIPanel将无法运行，但是当我不执行它时（如果这是有道理的）。

这是我运行程序时发生的事情

我希望输出打印到此GUIPanel（我必须删除对TourServer的调用以使其运行），如果您正在考虑“为什么不将它留在命令提示符中，您没有任何东西在你的GUIPanel中，除了文本区域之外呢？“，那很好，因为我打算稍后再添加更多内容：D

总结：我需要从GUIPanel类运行TourServer程序，当我尝试它时不会打开GUI面板本身

这是主要课程：

import java.net.*;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.awt.*;
import javax.swing.*;
import java.io.*;

这是TourServer Class

 /*
   The top-level Tour server, which waits for client connections
   and creates TourServerHandler threads to handle them.

   Details about each client are maintained in a TourGroup object
   which is referenced by each thread.

   Very similar to the multithreaded Chat server.

public class TourServer
{

  private TourGroup tg;
  static GameSession gameSession=new GameSession();
  public TourServer()
  // wait for a client connection, spawn a thread, repeat

    catch(Exception e)
    {  e.printStackTrace(); }
  }  // end of TourServer()


  // -----------------------------------

  public static void init(String args[]) {
      if (Integer.parseInt(args[0]) > 0) {
        PORT = Integer.parseInt(args[0]);
      } else {
          PORT = 5550;

} // end of TourServer class

Answer 1

你的GUI类中有这个构造函数：

public GUIPanel() {
        initComponents();
    }

在init函数之后添加这3个函数：

public GUIPanel() {
        initComponents();
        validate();
        pack();
        show();
    }

我确定之后的窗口会出现。不要停止在这一点，但尝试改进这个解决方案，因为如果我的内存服务，至少有一个这些函数被弃用。对不起，但我从Java 1.4开始就没有真正使用Swing。
