java動態表格

① 怎樣使用java swing畫一個表格，把輸出顯示到表格上，而且每10秒自動刷新一次

使用swing的JTable作為表格顯示數據
JTable table = new JTable(new DefaultTableModel(rowData, columnNames))
在參數里填入列數據和列名稱
把table放到一個JFrame里顯示
使用線程或者Timer定時更新數據
使用((DefaultTableModel) table.getModel()).fireTableDataChanged();讓頁面刷新

Vector<String> columnNames = new Vector<String>();
columnNames.add("統計項");

this.add(new JScrollPane(table), BorderLayout.CENTER);
time.schele(new TimerTask() {
@Override

update();
}
}, 0, 1000);
}

private void update() {
new SwingWorker<Object, Object>() {
protected Object doInBackground() throws Exception {
rowData.clear();
for (int i = 0; i < 4; i++) {
Vector<Object> info = new Vector<Object>();
info.add("測試");
info.add(count);
rowData.add(info);
}
count++;
return null;
}

protected void done() {
((DefaultTableModel) table.getModel()).fireTableDataChanged();
}
}.execute();
}

public static void main(String args[]) {
new test().setVisible(true);
}
