追加 JTextArea &稍后调用()

Question

我需要一些关于这个的帮助，

我基本上有menuVIP.java和vipKeyword.java。

这是 menuVIP.java

if (source == enter2) {
            Thread blah = new Thread() {
                String keyword = keyfield.getText();
                public void run() {
                    final String result;
                    vipKeyword vipK = new vipKeyword();
                    result = vipK.keyword(keyword);
                }

            };

            blah.start();

这是 vipKeyword.java

public class vipKeyword {

public String keyword(String keyword) {
    menuVIP vip = new menuVIP();

    String password;
    String tbl;
    String Final = null;
    int dot;
    try {

        databaseConnection dbC = new databaseConnection();
        dbC.connection();

        PreparedStatement prep2 = dbC.conn.prepareStatement("SELECT * "
                + "FROM Vip_tbl");
        ResultSet rs = prep2.executeQuery();

        while(rs.next()) {
            cellnumber = rs.getString(1);
            try {
            final String cell;
            cell = cellnumber;
                    SwingUtilities.invokeLater(new Runnable() {
                        menuVIP vip = new menuVIP();
                        public void run() {
                            vip.ta.append(cell + "\n");
                            vip.ta.repaint();
                        }

                    });
return keyword;
}

我需要知道的是如何在 SwingUtilities.invokelater() 中“附加”我的 vipKeyword 中的 Jtextarea？

注：ta = JTextArea

Answer 1

public String keyword(String keyword) {
     final menuVIP vip = new menuVIP(); // mark it as final

...

 SwingUtilities.invokeLater(new Runnable() { 
    //menuVIP vip = new menuVIP();   // comment it
