Pass in date from shell script to java program

Question

Hi,
I need to pass in some parameter to my java program.
eg 'java SomeProgram yyyy mm dd hh mm ss'
How do i use the shell script to generate the valeus for the year, mth day etc?
The program is running once everyday.
I tried $argu0 = `date+%y`
java SomeProgram $argu0
but not working... thanks for your help!

Then, why would you want to use 'date' to provide
'now' to a Java program when you could just use new
java.util.Date() which probably makes the same call
as the Unix 'date' command?That works until you need to use a date other than 'now.'
    public static final String ISO_DATE = "yyyy-MM-dd HH:mm:ss";
    public static void main(String[] args) {
        SimpleDateFormat sdf = (SimpleDateFormat) SimpleDateFormat
                .getDateTimeInstance();
        sdf.applyPattern(ISO_DATE);
        try {
            Date d = sdf.parse(args[0]);
            // rest of code here
        } catch (ParseException e) {
            // handle exception
    }Users will have to enclose there input with quotes otherwise the JVM will consider their input as two parameters, or you can change the pattern to include a character between dd and HH.
