linebreaks in output

Question

I'm building a program that receives an input string with linebreaks through a GUI, splits it in lines, then in words, and then passes it word by word to a method I still have to implement, translate, which will somehow take a word and swap it with an appropriate one. At the moment, with the following code:

public class HakkaTranslator extends JFrame {

    /**

    public HakkaTranslator() {
        initComponents();
    }

    /**

        inputField = new JTextArea();

        hakkaCharField = new JLabel();
        mandCharField = new JLabel();

        translateButton.setText("Translate");
        translateButton.addActionListener(new java.awt.event.ActionListener() {

        try {
            for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
                if ("Nimbus".equals(info.getName())) {
                    javax.swing.UIManager.setLookAndFeel(info.getClassName());
                    break;
                }
            }
        } catch (ClassNotFoundException ex) {
            java.util.logging.Logger.getLogger(HakkaTranslator.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        } catch (InstantiationException ex) {
            java.util.logging.Logger.getLogger(HakkaTranslator.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        } catch (IllegalAccessException ex) {
            java.util.logging.Logger.getLogger(HakkaTranslator.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        } catch (javax.swing.UnsupportedLookAndFeelException ex) {
            java.util.logging.Logger.getLogger(HakkaTranslator.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        }
        //

        /* Create and display the form */
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new HakkaTranslator().setVisible(true);
            }
        });
    }

    // Variables declaration - do not modify//GEN-BEGIN:variables
    private JLabel hakkaCharField;
    private JTextArea inputField;
    private JLabel mandCharField;
    private JLabel pinyinField;
    private JButton translateButton;
    // End of variables declaration//GEN-END:variables
    String inpText;
}

I have gotten practically everything working, save for the translate method, which is the next step, and for the fact that, whether I put System.lineSeparator() or " " as the argument in the line translate(System.lineSeparator()), the result is invariably a wide space, while I want a linebreak. How do I make the linebreak appear in the output?

I'd post an image but I don't have enough reputation. Please note that I've just tried putting "" "" instead of System.lineSeparator(), in light of this question, but that didn't work either. I remember trying the MultiLineUI answer's command and getting a cannot find symbol or the likes.

    @Override
    public void actionPerformed(java.awt.event.ActionEvent e) {

        inpText = inputField.getText();
        String[] lines = inpText.split("
");
        String[][] words = new String[lines.length][20];
        for(int i=0;i");
        for(int i=0;i");
        }
        translate("");
    }
