程序必须从 MySQL 数据库下载数据。并填写 JList。我想绑定(bind)这个数据。
这里有一个代码:
Connection connection = null;
String dbtime;
String query = "Select * FROM EMP";
String[] celDatas = null;
String[] celNames = null;
try {
(...)
Statement stmt = connection.createStatement();
ResultSet rs = stmt.executeQuery(query);
ResultSetMetaData rsmd = rs.getMetaData();
int NumOfCol = rsmd.getColumnCount();
celNames = new String[NumOfCol];
celDatas = new String[NumOfCol];
for(int weq=1; weq<=NumOfCol; weq++) {
System.out.println(rsmd.getColumnName(weq));
celNames[weq-1] = rsmd.getColumnName(weq);
while (rs.next()) {
dbtime = rs.getString(weq);
System.out.println(dbtime);
celDatas[weq-1] = dbtime;
}
rs = stmt.executeQuery(query);
System.out.println();
}
} catch (ClassNotFoundException e) {
} catch (SQLException e) {
}
final JList source = new JList(celDatas,celNames);
JScrollPane pane = new JScrollPane(source);
pane.setSize(f.getSize().width-60,300);
pane.setLocation(30,20);
我有问题
final JList source = new JList(celDatas,celNames);
它在 Netbeans 中显示了这个问题:http://dl.dropbox.com/u/8455739/Java-Problem.png
最佳答案
//String[] celDatas = null;
String[][] celDatas = null;
String[] celNames = null;
...
//final JList source = new JList(celDatas,celNames);
final JTable source = new JTable(celDatas,celNames);
关于java - JTable 使用数组字符串。这些数据在 try-catch 中，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10161443/
