用JLabel 或Label
我给你写了个开头
public class mainFrame extends JFrame{
JLabel jl = new JLabel("用户名称:");
JTextField jtf = new JTextField();
JPanel jp_group = new JPanel();
public loginFrame() {
try {
jbInit();common.mysession.dataTrf.getValue("main");
} catch (Exception exception) {
exception.printStackTrace();
}
}
本人急忙做的:有什么不合要求的请再告诉我:

将这段代码拷贝到UseBirthday类中和你的比较一下看看
public class UseBirthday {
public static void main(String[] args) {

a.GetBirthday();
a.Birthday(2008,5,12);
a.GetBirthday();
}

private int Year, Month, Day;
Birthday(){
Year=2000;
Month=1;
Day=1;
}
Birthday(int y,int m,int d) {
Year = y;
Month = m;
Day = d;
}
public void Birthday(int y,int m,int d){

}
int Gety() {
return Year;
