我需要一些帮助,
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()中从我的vipKeyword“追加”Jtextarea?
注意:ta = JTextArea
答案 0 :(得分: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
