Thread: How do you define things from specific keyboard inputs?

Well firstly I think there's a problem in calling the nextDouble() method when you're asking for year/month/day (the user will likely type something like 2011/11/30, which includes "/" characters, which will make the nextDouble() method return an error). So perhaps you should use the the Scanner's next() method instead.

Secondly, when you use the next() method, it will return a String. So, assuming the user enters his/her input in the correct format, you could use a substring (which gets a certain mini-string of characters from within a String). Note that instead of directly assigning CurrentYear to the myScanner.next(), you should probably first assign myScanner.next() to some dummy variable (normally I just create a String dummy that temporarily holds the input String, so that I can do whatever I want with it).

You have asked that the user put the year in the first four characters, so those are the ones you want the substring to be of. Note that substring() still returns a String, so once you have the characters that represent the year, you'll have to use Double.parseDouble() or Integer.parseInt() to get those characters turned into a number.

Hopefully that made sense...
