何时选择该月的第一天，例如:- 2014 年 4 月 1 日，
它在jdatechooser中显示为:91-04-2014，我的dateFormatString是:“dd-mm-yyyy”
这是我的代码:
public class Student extends javax.swing.JFrame {
/**
* Creates new form Student
*/
static JFormattedTextField gradeText;
public Student() {
//Methods
initComponents();
KeyTypos();
updateTable();
//Frame settings
pack();
setLocationRelativeTo(null);
ImageIcon ic = new ImageIcon("src\\main\\java\\com\\cyrax\\images\\Icon.png");
this.setIconImage(ic.getImage());
//initializations
stud.clearSelection();
gradeText = ((JSpinner.DefaultEditor) grd.getEditor()).getTextField();
dob.setDateFormatString("DD-MM-YYYY");
}
public final void KeyTypos() {
try {
gradeText = ((JSpinner.DefaultEditor) grd.getEditor()).getTextField();
gradeText.addKeyListener(new KeyAdapter() {
@Override
public void keyTyped(KeyEvent e) {
char c = e.getKeyChar();
if (!(c >= '0' & c <= '9') | c == e.VK_PERIOD) {
Toolkit.getDefaultToolkit().beep();
e.consume();
}
}
@Override
public void keyReleased(KeyEvent e) {
if (!gradeText.getText().toString().isEmpty()) {
int val = Integer.parseInt(gradeText.getText());
if (val > 11) {
String oldVal = gradeText.getText().toString();
char str[] = oldVal.toCharArray();
StringBuilder sb = new StringBuilder(oldVal);
sb.deleteCharAt(sb.length() - 1);
String newVal = sb.toString();
gradeText.setText(newVal);
}
}
}
});
}catch(Exception e){
e.printStackTrace();
}
}

请帮我解决这个问题
谢谢
最佳答案
DD 是一年中的一天。您需要 dd 表示一个月中的某一天。请参阅Javadoc .
关于java - 在 JDateChooser 中选择日期时，日期不正确。为什么？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23081215/
