难以增加

我在增加称为“正确”的计数器时遇到一些困难。而不是增加它不断地打印出1，并且不将数字加在一起。我尝试使用另一个变量求和，但是没有运气。有什么想法为什么它没有增加？

码：

    tf.addActionListener(new ActionListener() {
    int wrong = 0;
    int right = 0;

    @Override
    public void actionPerformed(ActionEvent e) {// enter key
        JTextField tf = (JTextField) e.getSource();
        letter = tf.getText();
        tf.setText("");
        // tf.requestFocus();
        jlLetsUsed.setText(jlLetsUsed.getText() + letter + " ");// sets

        char[] jlabelText = jlLines.getText().toCharArray();// converts

        char userEnteredChar = letter.charAt(0);
        System.out.println(wordList[level]);
        if (!wordList[level].contains(letter)) {
            wrong++;
            if (wrong == 6) {
                JOptionPane.showMessageDialog(frame,
                        "He's dead, game over." + "\n"
                                + "The word was " + wordList[level]
                                + ".", "You Lost",
                        JOptionPane.INFORMATION_MESSAGE, ic);
                GameStructure restart = new GameStructure();
                level = (int) (Math.random() * 64);// generate new
                                                    // random word
                restart.window();
            }
            return;
        }
        int i = 0;
        for (i = 0; i < wordList[level].length(); i++) {
            if (wordList[level].charAt(i) == userEnteredChar) {
                jlabelText[3 * i] = ' ';
                jlabelText[3 * i + 1] = userEnteredChar;
                right++;
            }// end if
        }// end for
        jlLines.setText(String.valueOf(jlabelText));
        if (jlabelText.length / 3 == right) {
            JOptionPane.showMessageDialog(frame, "You got the word!.",
                    "You Lost", JOptionPane.INFORMATION_MESSAGE, ic);
            GameStructure restart = new GameStructure();
            level = (int) (Math.random() * 64);// generate new
                                                // random word
            restart.window();
        }
    }// end actionPerformed method
});
