Splitting JText Area into two

I'm currently programming a messanger program in Java. I have box where I type in my message and another box where it appears after I have sent it and I receive a response. The second box is JText Area and I was wonder how to I make my message appear on the right hand side of the box and the response on the left side (like iMessage). I can't seem to find how to position the strings in the jTextArea accordingly.

Instead of using JTextArea, try to use JTextPane as below.

JTextPane textPane = new JTextPane();
frame.getContentPane().add(textPane, BorderLayout.CENTER);
textPane.setContentType("text/html");
textPane.setEditable(false);

After creating JTextPane add styles as below.

StyledDocument doc=textPane.getStyledDocument();
SimpleAttributeSet right =new SimpleAttributeSet();
SimpleAttributeSet left =new SimpleAttributeSet();

StyleConstants.setAlignment(right, StyleConstants.ALIGN_RIGHT);
StyleConstants.setAlignment(left, StyleConstants.ALIGN_LEFT);

Now add texts to the JTextPane

   try {

        doc.insertString(0, "First Line aligned left\n", left);
        doc.insertString(doc.getLength(), "Second line Aligned right\n", right);

    } catch (Exception e) {
        e.printStackTrace();
    }

You will get the result as below.

Hope you got the answer you want.
