    Default DateFormat and SimpleDateFormat

    Hi All -

    Been struggling for this for the last 4 days or so...hoping someone can help.
    I have a file that I am parsing dates from in the below format:

    2012/58:20:36:41
    2012/54:13:34:56
    2012/54:15:08:16

    I move these into an array (data) as a string. I want to take the string --> change it into a date object --> then print it. Clearly I am struggling with my understanding of what SimpleDateFormat does....when printing I want to maintain the same format that I have. Any and all help is appreciated. Thanks

    for (int i = 0; i<data.size(); i++){
     
                DateFormat eachDate = new  SimpleDateFormat ("yyyy/DDD:HH:M:ss");
     
     
                try {
     
                    Date d1 = eachDate.parse(data.get(i));
                    System.out.println(d1);
     
                }    
     
                catch(ParseException pe) {
                    System.out.println("ERROR: could not parse date in string");                        
     
                }
            }

    If you define the data as an array, data.get(i) should be an object, not a string.Then eachDate.parse() need a string as parameter.

    Hi arvindbis,

    I'm passing string variables that are stored in the Array data.

    They are in this format:

    2012/58:20:36:41
    2012/54:13:34:56
    2012/54:15:08:16

    when printing I want to maintain the same format that I have.
    You are printing the Date object, which uses the Date.toString() method. If you want to print a Date object in the same format as the string passed to the parse method, then use the DateFormat.format() method.
