Wäre dankbar wenn mir jemand helfen könnte!

Mfg,

Dein [c]ausg [/c] ist null ! Daher machts PENG! in Zeile 137 bei [c]ausg.charAt(j);[/c]

 

[Skonrox]

Jau hab ich schon gefunden, aber nun habe ich das problem, das z.b. wenn man " " eingibt, also eine leerstelle, dann wird nicht KeyEvent.VK_SPACE, sondern ganz falsch:
S
P
A
C
E,
brauche wieder einmal hilfe :/

Mit freundlichen Grüßen,
skonrox!

Also du hast ja immer noch nicht gesagt, was du eig. genau machen möchtest und vor allem auch nicht wie dein jetziger Stand aussieht...
Aber du willst ja anscheinend zu einer bestimmten Taste das KeyEvent, bzw den String ermitteln, richtig? Du könntest das auch evtl. via Reflection lösen...hänge doch einfach an das Textfeld einen KeyListener - keyReleased ran.
kleine Demo:

    public static void main(String... args) {
	final int PUBLICSTATICFINAL = Modifier.PUBLIC | Modifier.STATIC | Modifier.FINAL;
	JFrame frame = new JFrame();
	JPanel panel = new JPanel();
	JTextField feld = new JTextField(20);
	feld.addKeyListener(new KeyAdapter() {
	    @Override
	    public void keyReleased(KeyEvent e) {
		for (Field f : KeyEvent.class.getDeclaredFields()) {
		    if (f.getModifiers() == PUBLICSTATICFINAL && f.getType() == int.class) {
			try {
			    if (e.getKeyCode() == f.getInt(null)) {
				System.out.println(f.getName());
				break;
			    }
			} catch (IllegalArgumentException e1) {
			    e1.printStackTrace();
			} catch (IllegalAccessException e1) {
			    e1.printStackTrace();
			}
		    }
		}
	    }

	});
	panel.add(feld);
	frame.add(panel);
	frame.pack();
	frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	frame.setLocationRelativeTo(null);
	frame.setVisible(true);
    }

Ansonsten, erkläre vllt noch mal was du genau vor hast - wie dein Stand momentan ist, etc.

Also, ich hänge jetzt einmal das komplette programm mit bedeutungen rein:

		return jContentPane;
	}
}

Und was das programm machen soll:
Es soll das KeyEvent schreiben mit den einzelnen char die für ein "robot" programm benötigt werden, wodurch es erleichtert wird sowas zu schreiben. Mein problem ist es das für eine Leerstelle (" ") der befehl ("KeyEvent.VK_SPACE") benötigt wird, also muss dort statt ("KeyEvent.VK_S", "+""".VK_P"+""".VK_A"+""".VK_P"+""".VK_E" stehen, und das möchte ich innerhalb der schleife machen.

Skonrox!
