How to set list of symbles converted to alphabet?

Question

I'm making a system to convert Morse cord to English alphabet. I'm using JTextfeild called "write" to type text and another JTextfeild call "View" to view which is typed on write.

But I can only set one Morse cord for one time.

As an example if I type A on "Write" textfeild it it is only printing ".-" . And when I type "B" again then view textfeild set "-..." . I want to print number of letters.

Given below is my source cord.

private void writeKeyReleased(java.awt.event.KeyEvent evt) {                                  

    if (evt.getKeyCode() == 65) {
        view.setText(".-");
    } else if (evt.getKeyCode() == 66) {
        view.setText("-...");
    } else if (evt.getKeyCode() == 67) {
        view.setText("-.-.");
    } else if (evt.getKeyCode() == 68) {
        view.setText("-..");
    } else if (evt.getKeyCode() == 69) {
        view.setText(".");
    } else if (evt.getKeyCode() == 70) {
        view.setText("..-.");
    } else if (evt.getKeyCode() == 71) {
        view.setText("--.");
    } else if (evt.getKeyCode() == 72) {
        view.setText("....");
    } else if (evt.getKeyCode() == 73) {
        view.setText("..");
    } else if (evt.getKeyCode() == 74) {
        view.setText(".---");
    } else if (evt.getKeyCode() == 75) {
        view.setText(".-.-");
    } else if (evt.getKeyCode() == 76) {
        view.setText(".-..");
    } else if (evt.getKeyCode() == 77) {
        view.setText("--");
    } else if (evt.getKeyCode() == 78) {
        view.setText("-.");
    } else if (evt.getKeyCode() == 79) {
        view.setText("---");
    } else if (evt.getKeyCode() == 80) {
        view.setText(".--.");
    } else if (evt.getKeyCode() == 81) {
        view.setText("--.-");
    } else if (evt.getKeyCode() == 82) {
        view.setText(".-.");
    } else if (evt.getKeyCode() == 83) {
        view.setText("...");
    } else if (evt.getKeyCode() == 84) {
        view.setText("-");
    } else if (evt.getKeyCode() == 85) {
        view.setText("..-");
    } else if (evt.getKeyCode() == 86) {
        view.setText("...-");
    } else if (evt.getKeyCode() == 87) {
        view.setText(".--");
    } else if (evt.getKeyCode() == 88) {
        view.setText("-..-");
    } else if (evt.getKeyCode() == 89) {
        view.setText("-.--");
    } else {
        view.setText("--..");
    }

}

I'm making a system to convert Mose cord to English alphabet. I'm using jtextfeild called "write" to type text and another jtextfeild call "View" to view which is typed on write.

• use DocumentListener for JTextComponents instead of low_level KeyListener, otheriwise you can't be able to input sequence of chars from (for example) Ctrl+C (SystemClipBoard), or remove selected chars, then output to anther JComponents freeze without any, no changes are made, because KeyListener can firing an Event from single Char only

• plus you can use DocumentFilter in the case that you want to replace, remove, modify single char or chars sequence typed by user into JTextField

for example

import java.awt.GridLayout;
import javax.swing.*;
import javax.swing.event.DocumentEvent;
import javax.swing.event.DocumentListener;

public class TextLabelMirror {

    private JPanel mainPanel = new JPanel();
    private JTextField field = new JTextField(20);
    private JTextField field1 = new JTextField(20);

    public TextLabelMirror() {
        field.getDocument().addDocumentListener(new DocumentListener() {

            @Override
            public void changedUpdate(DocumentEvent e) {
                updateLabel(e);
            }

            @Override
            public void insertUpdate(DocumentEvent e) {
                updateLabel(e);
            }

            @Override
            public void removeUpdate(DocumentEvent e) {
                updateLabel(e);
            }

            private void updateLabel(DocumentEvent e) {
                java.awt.EventQueue.invokeLater(new Runnable() {

                    @Override
                    public void run() {
                        field1.setText(field.getText());
                    }
                });
            }
        });

        mainPanel.setLayout(new GridLayout(1, 0, 10, 0));
        mainPanel.add(field);
        mainPanel.add(field1);
    }

    public JComponent getComponent() {
        return mainPanel;
    }

    private static void createAndShowUI() {
        JFrame frame = new JFrame("TextLabelMirror");
        frame.getContentPane().add(new TextLabelMirror().getComponent());
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        java.awt.EventQueue.invokeLater(new Runnable() {

            @Override
            public void run() {
                createAndShowUI();
            }
        });
    }
}
