我正在尝试JPanel使用i.add(jp, BorderLayout.EAST);它来设置我的位置,但它不起作用.有什么想法吗？我在这里先向您的帮助表示感谢.

/* INSTANCE DECLARATIONS */
private JTextField tf;//text field instance variable
private JLabel jl2;//label instance variable


/*****************
 * WINDOW METHOD *
 * ***************/
public void window() {

    LoadImageApp i = new LoadImageApp();//calling image class

    JFrame gameFrame = new JFrame();//declaration
    JPanel jp = new JPanel();
    JLabel jl = new JLabel("Enter a Letter:");//prompt with label

    tf = new JTextField(1);//length of text field by character
    jl2 = new JLabel("Letters Used:    ");

    jp.add(jl);//add label to panel
    jp.add(tf);//add text field …

我的for循环没有更新,我得到用户每次输入的相同字母的输出"mmmmmm"或"ffffff".我希望它每次都能不断更新下一个字母,如下所示:

用户输入:m
用户输入:f
用户输入:d

输出:"使用的字母:mfd"

int j = 0;  
String []used = new String[6];  
for(j = 0; j<6; j++){  
    used[j] = tf.getText(); //get user input  
}  
jl2.setText("Letters Used:    " + used[0] + used[1] + used[2] + used[3] + used[4] + used[5] );  

我在增加我的计数器方面遇到了一些困难.不是递增它而是不断地打印1并且不将数字加在一起.我尝试使用另一个变量来累计计数器,但没有运气.任何想法,为什么它不增加？

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 …
