从JDateChooser获取值作为文件名

Question

I'm trying to get value from JDateChooser and use it as a filename I've created a file with a path, I can write on it, but the only problem is I can't change its name to the variable(data from JDateChooser )

Here is the part of the code:

JButton btnSave = new JButton("Save"); 
    btnSave.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            String text = textField.getText();
            JDateChooser day = new JDateChooser();
            try{
                    File remindFile = new File("\\path", day + ".txt");
                    remindFile.createNewFile();
                    BufferedWriter writer = new BufferedWriter(new FileWriter(remindFile));
                    writer.write(text);
                    writer.close();
                    }
                    catch(Exception k)
                    { System.out.println("Oops");}

            textField.setText(null);

        }
    });
    btnSave.setFont(new Font("Tahoma", Font.PLAIN, 13));
    btnSave.setBounds(401, 215, 108, 30);
    panel.add(btnSave);

In the result created file gets name as:

com.toedter.calendar.JDateChooser
[JDateChooser,0,0,0x0,invalid,layout=java.awt.BorderLayout,alignmentX=0.0,alignmentY=0.0,border=,flags=9,maximumSize=,minimumSize=,preferredSize=]

How can I fix it?

Answer 1

You are actually appending the JDateChooser object itself, instead of a String representation of its selected Date :

File remindFile = new File("C:\\Users\\student_ib\\eclipse\\d", day + ".txt");

Try :

Date chosenDate = day.getDate();
DateFormat dateFormat = new SimpleDateFormat("yyMMdd");

File remindFile = new File("C:\\Users\\student_ib\\eclipse\\d", dateFormat.parse(chosenDate) + ".txt");

Answer 2

您必须调用day.getDate().getDay()从JDateChooser获取日期，而不要使用day本身。

Answer 3

Check the documentation for JDateChooser .

You will need to first get the date value via either .getDate() or .getCalendar() , then you should use something like SimpleDateFormat to format the date.

Answer 4

Thank you all for your answers. Using your advices I solved it in this way:

            int day = calendar_1.getDayChooser().getDay();
            int month = calendar_1.getMonthChooser().getMonth();
            int year = calendar_1.getYearChooser().getYear();
            String name = "" + day + month + year;
            File remindFile = new File(name + ".txt");
