I'm working currently on java project that uses Arabic Language, I found difficulty in writing in Arabic as shown in the image:

enter image description here

  1. I wrote Arabic without any edit.

  2. I added a reverse() method, it worked good but the letters aren't attached to each other, they're separate.

    StringBuilder input = new StringBuilder();
input.append(jTextField2.getText());
input = input.reverse();
jTextField1.setText(input.toString());

  3. I use site the flip the text, it didn't work as well.

  4. I use the same site, but with jLabel it worked.

other method I use, but didn't work:

  • Try Orientation jTextField1.applyComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);

  • Change the IDE encoding to URT-8 (I'm using Netbeans-JDK8).

Can anyone help me how to write & print Arabic in java correctly?

  • Have you tried to set the locale? jTextField1.getInputContext().selectInputMethod(new Locale("ar", "LB")); – dirbacke Aug 10 '18 at 12:41

    Nonetheless, a real [mcve] would be helpful. As in: putting a small class with a real main method that puts up that UI, and that people can simply run themselves to see your issue. – GhostCat Aug 10 '18 at 12:42
  • Please add to your question the exact sequence of Arabic characters (as text, not just as an image) that you are finding cannot be properly reversed. – VGR Aug 10 '18 at 16:36
  • @dirbacke yes, didn't work as well. – LaLa Aug 15 '18 at 22:40
  • @VGR I don't know if I understand u well, but this is what i'm aiming to get: (مرحبا بالعالم) – LaLa Aug 15 '18 at 22:44
  • Is that the reversed text? If it is, then what is the original text you are inputting before reversing it? – VGR Aug 16 '18 at 02:18

Please refer to this question - Forcing RTL order in a JTextArea

Here is a sugestion to start the string with the character \u202e to force the text to be RTL.

Also i think it is not good approach to reverse the string, as it is not good user experience when the user do "copy paste", as he will copy reversed string...

  • I added the code `jTextField1.getDocument().putProperty( TextAttribute.RUN_DIRECTION, TextAttribute.RUN_DIRECTION_RTL);` but didn't work with. – LaLa Aug 15 '18 at 22:38

A string entirely composed of characters from the Arabic block should render with correct RTL presentation without any directionality control characters. If it does not, it is likely that you have a problem with your operating system configuration, not with your Java code. Reversing the string is a terrible idea. Trying for visual-order rendering is going to get all messed up.
