Java swing 实现下拉框和文本框同步显示

想要MyEclipse中的swing中实现下拉框和文本框实现，对下拉框创建MouseEvent、ItemEvent、ActionEvent

private void xingbieMouseClicked(java.awt.event.MouseEvent evt) {
// TODO add your handling code here:
setSelectedItem(evt, this.xingbie1);
}


private void xingbieItemStateChanged(java.awt.event.ItemEvent evt) {
// TODO add your handling code here:
setSelectedItem(evt, this.xingbie1);
}

private void setsex1(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
setSelectedItem(evt, this.xingbie1);

}

public static void setSelectedItem(AWTEvent e, JTextField ipTextField) {
JComboBox target = (JComboBox) e.getSource();
String selectedPort = (String) target.getSelectedItem();
ipTextField.setText(selectedPort);


}
