我从abcd获取EnterOrderID的值,并且想在fillCombobox中使用它,如何实现呢?
我是编程新手,请帮忙。
我尝试将其设置为公开仍然没有运气
有人可以引导我通过
public class abcd extends JFrame {
private JPanel contentPane;
private JComboBox comboBoxRSU;
public JTextPane EnterOrderID;
/**
* Launch the application.
*/
Connection conn = null;
/**
* Create the frame.
*/
public abcd() {
EnterOrderID = new JTextPane();
EnterOrderID.setContentType("integer");
EnterOrderID.setBounds(114, 11, 224, 20);
contentPane.add(EnterOrderID);
JButton btnGetdetails = new JButton("Getdetails");
btnGetdetails.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
try {
String query = "select distinct p.RM_ORDERID,s.VALID_VALUE as GID,t.TASK_NUMBER, p.INSITEA_CITY, p.ORDER_TYPE from data p,value s,task t where s.VALUE_LABEL = 'INDICATOR' and t.TASK_TYPE = 'LIS'and p.DOCUMENT_NUMBER = ?";
PreparedStatement pst = conn.prepareStatement(query);
pst.setString(1, (String) EnterOrderID.getText());
//is is the value input by user EnterOrderID
ResultSet rs = pst.executeQuery();
while (rs.next()) {
textFieldcrm.setText(rs.getString("RM_ORDERID"));
textGID.setText(rs.getString("GID"));
}
);
comboBoxRSU = new JComboBox();
comboBoxRSU.setBounds(354, 74, 138, 20);
contentPane.add(comboBoxRSU);
fillComboBox();
}
public void fillComboBox() {
try {
String query = "select distinct s.VALID_VALUE as rsu,p.INSITEA_CITY from value s,data p where s.VALUE_LABEL = 'GIS_RSU_DLC' and p.INSITEA_CITY = (select INSITEA_CITY from data where DOCUMENT_NUMBER = ?)";
//(select INSITEA_CITY from data where DOCUMENT_NUMBER = ?)
PreparedStatement pst = conn.prepareStatement(query);
pst.setString(1, (String) EnterOrderID.getText());
//Here I want to use it again, i do want user to input value again and again.
ResultSet rs = pst.executeQuery();
while (rs.next()) {
comboBoxRSU.addItem(rs.getString("rsu"));
}
}
}
public JTextPane EnterOrderID是一个类变量,因此可以在fillComboBox()中使用它。
