java編程問題?

Staff_C.java類中

public Object[][] depart() {

DataBase db3 = new DataBase();

String sql = "select * from depart_table";

ResultSet rs = db3.executeQuery(sql);

DataMap mp_depart = new DataMap(rs);

Object[][] depart = mp_depart.get_DataMap_Array();

return depart;

}

顯示類中

jLabel2.setText("部門ID:");

jLabel2.setBounds(new Rectangle(54, 140, 61, 28));

Staff_C sm = new Staff_C();

dep = sm.depart();

for (int i = 0; i < dep.length; i++) {

partBox.addItem(dep[i][1].toString());

}

修改下就可以用 別說不會用了
