Thread: Beginner... stuck on how to use FormattedFields in java for inserting dates

I know the below code is supposed to format the FormattedTextField but it doesn't seem to do anything to the form (shown in the picture below). I was wanting, when the form loaded: the text field to look something like this

00/00/2014 - 00:00 am


Where the user is able to

- enter datelike information around the symbol separators ( / or : )

- But where the user could not remove these symbol separators

Code:

  package datefield;
 
    import javax.swing.JFormattedTextField;
    import javax.swing.text.DateFormatter;
 
 
    public class NewJFrame extends javax.swing.JFrame {
 
        public NewJFrame() {
            initComponents();
            formattedTextField();
        }
 
public void formattedTextField()
   {
        jFormattedTextField1 = new JFormattedTextField(new SimpleDateFormat("MM/dd/yy - mm:HH"));
        jFormattedTextField1.setValue(new Date());
        add(jFormattedTextField1);
   }

hello,

As per my understanding of the problem, you want the user to input a date on the text field then as he/she type the text is automatically converted to the format that you want?

regards

[edit]

sorry i think i get what you mean now,

i think you could use a MaskFormatter

JFormattedTextField jFormattedTextField1 = new JFormattedTextField(new MaskFormatter("##'/##'/## '- ##':##"));

just make sure the initial value will fit in the specified mask criteria

source :
http://docs.oracle.com/javase/7/docs...Formatter.html

How do I use the above code, when I try to execute it from within a button nothing happens.


What I was hoping for, was as soon as the form loaded three backslashes where locked into place in the jFormatedTextField wherein the user could type a date around them e.g. 10/10/2014

using your code above

 
        jFormattedTextField1 = new JFormattedTextField(new SimpleDateFormat("MM/dd/yy - mm:HH"));
        jFormattedTextField1.setValue(new Date());
        add(jFormattedTextField1);

make some alterations

initialize your : jFormattedTextField1 like so

JFormattedTextField jFormattedTextField1 = new JFormattedTextField(new MaskFormatter("##'/##'/## '- ##':##"));

is guess youd want to have initial value using
jFormattedTextField1.setValue(new Date()); ?

you have to make the for mat of new Date match the format of the mask using simpledateformater

or else onload the textfield would be blank.

if correctly applied

it should have

02/11/14 - 02:57

note : the slash, dash and colon will not be deleted even if the user tries to. i already tried it with your code
