Création d'une application à l'intérieur d'une interface graphique en Java

Question

J'ai un problème avec lequel j'ai traité cette semaine. Vous voyez, je suis nouveau à Java, donc c'est probablement ...

De toute façon, j'ai commencé un projet par pure curiosité. Je l'ai fait en Java, mais en style simple CMD, ce qui n'est pas très joli. Il appelle l'un de mes dix programmes, choisis par l'utilisateur en utilisant "Case". Par exemple: Si vous tapez 1, il passera au programme 1. Après l'avoir terminé, il reviendra à la sélection jusqu'à ce que l'utilisateur appuie sur 0.

Ensuite, j'ai essayé de créer une interface graphique pour cela. J'ai été capable de créer le sélecteur seul et le faire répondre aux numéros choisis. Si vous appuyez sur 1 et cliquez sur ok, il vous dira que vous avez choisi le programme 1.

Cependant, je n'ai pas réussi à faire fonctionner le programme. J'ai essayé de faire apparaître le programme dans un jPanel, une partie de l'interface graphique principale. J'ai échoué lamentablement.

Le programme s'exécute séparément mais je ne peux pas les faire fonctionner ensemble comme le CMD.

Les applications ont été faites dans Eclipse SDK 3.5.2 Les interfaces graphiques ont été faites dans Netbeans IDE 6.8

Voici le code pour l'interface graphique uniquement (les impressions sont PT-BR, ma langue maternelle):

Je ne peux pas deviner ce que vous cherchez un moyen d'exécuter le programme du terminal? Utilisez Runtime.getRuntime(). Exec (commande_call_command); L'exemple va imprimer le contenu du dossier sous GNU/Linux:

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"); 
    } 
}
