    Default Comparing Strings

    If I wanted to take strings in from the user through a GUI say day, month, year. I am looking for a way to organize those incoming strings. I am going to add this information to a queue. However, I want the people who put in the earliest day, month, and year to be put into the queue first followed by the next earliest so on and so forth. Has anyone done anything like this before? I was thinking what I would need to make a method that would compare the information. Any clues on how I can do this is there a fairly straightforward method for doing this or no?

    Parse the String into the appropriate class instance, for example with date/time information you could use DateFormat to parse into a Date
    DateFormat (Java Platform SE 7 )

    However, I want the people who put in the earliest day, month, and year to be put into the queue first followed by the next earliest so on and so forth.
    See PriorityQueue (Java Platform SE 7 )

    Hey this is good thank you, however; I am still having issues. So I can get it to print like today's date:

    package testdates;
    import java.text.DateFormat;
    import java.util.Date;
     
    public class Testdates {
     
        public static void main(String[] args) {
            Date today = new Date();
     
            DateFormat fullDate = DateFormat.getDateInstance(DateFormat.FULL);
     
            System.out.println(fullDate.format(today));
        } 
    }

    but I am still confused about the parsing part. Does this class have a method that will compare incoming strings or something I missed in the DateFormat (Java Platform SE 7 )? Also, I have to use my own queue I am not allowed to use the java class queue but I already have a circular queue that I build earlier that is going to handle dequeuing and whatnot, would you like to see it?

    The Date class implements the Comparable interface (see it's compareTo method), the DateFormat class is for formatting and parsing - I recommend studying the API for these classes if you intend to use them as the API can answer many of your questions.

    I have to use my own queue I am not allowed to use the java class queue but I already have a circular queue that I build earlier that is going to handle dequeuing and whatnot, would you like to see it?
    Do you have a question about this class in particular?
