在Java中的GUI中進行應用程序展示

我有一個問題，我一直在處理這個星期。你看，我是新來的Java，所以這可能是...在Java中的GUI中進行應用程序展示

無論如何，我已經開始了純粹的好奇心項目。我在Java中完成了它，但是以簡單的CMD風格，這不是很漂亮。它稱爲我的十個程序之一，由用戶使用「案例」選擇。例如：如果你輸入1，它將進入程序1.完成後，它會返回到選擇狀態，直到用戶按下0.

之後，我一直在試圖爲它做一個GUI。我已經能夠單獨創建選擇器並使其響應所選的數字。如果按1並單擊確定，它會告訴您已經選擇了程序1.但是，我卻無法使其運行該程序。我一直在試圖讓程序顯示在jPanel中，這是主GUI的一部分。我失敗了。

該程序單獨運行，但我不能讓它們像CMD一樣運行。

這些應用都在Eclipse SDK 3.5.2製成的的GUI是在NetBeans IDE中取得6.8

下面是唯一的GUI代碼（版畫是PT-BR，我的母語）：

我不能猜測你正在尋找一種方式從終端運行程序？使用Runtime.getRuntime（）。exec（program_call_command）; 示例將在GNU/Linux上打印文件夾內容：

public class Executor { 
     public static void main(String[] args) throws IOException { 
      Process p = Runtime.getRuntime().exec("ls"); 
      InputStream in = p.getInputStream(); 
      int size = in.available(); 
      byte[] buf = new byte[size]; 
      in.read(buf); 
      System.out.println(new String(buf)); 
     } 
    } 

Or maybe if all your programs are in java, you can create a new thread for each and call main method for every program. 

public class Executor { 
    public static void main(String[] args) throws IOException { 
     System.out.println("Executor started"); 
     Thread thread = new Thread(){ 
      @Override 
      public void run() { 
       Prog_1.main(null); 
      } 
     }; 
     thread.start(); 

     System.out.println("Executor finished"); 
    } 

} 

class Prog_1{ 
    public static void main(String[] args) { 
     System.out.println("I am going to sleep"); 
     try { 
      Thread.sleep(2000); 
     } catch (InterruptedException e) { 
      System.out.println("Really, don't whant to"); 
     } 
     System.out.println("Its time to wake up"); 
    } 
}
