String

Substring, or better, String.split(). Although I wonder why you don't keep a date as Date, and use SimpleDateFormat to make human-readable Strings of it as you need them.

if you can rely on the date format to be always that way,

search for the third space and cut before it.

String.split generates an array of Strings, it breaks a string down into substrings with the supplier separator.

I'd use substring e.g.

int lastspace = timestring.lastIndexOf(' '); // last space

lastspace = timestring.lastIndexOf(' ', lastspace); // previous space

if(lastspace > 0)

lastspace = lastspace.substring(0, lastspace);

Or, more likely, I'd parse it with a DataFormat, then format it back to a string (thus checking it really was a valid time).

ok I'm still stuck on this problem becuase the website is a little different than i though... i have a 2-D array which contains the row and column (table[row][column] ) in column 1 is the date and the only thing i want to change but i have 2 different formats...7/26/2007 9:00:00 PM and July 09 2007 9:00 PM any suggestions on how i can replace table[row][1] with just the date?

I notice many forum members render that:

O_o

Your basic problem is to turn a String into a Date. (Unless you have

a compelling reason *not* to turn it into a date!) So this breaks into

two subproblems:

1. When to parse the date string.

2. How to parse it.

1. It's hard to answer 1 without seeing some code, but the sooner the better

is my gut feeling, and I have a huge gut. Your 2-D array sounds like a

big mistake. You should have a collection of appropriate objects instead:

http://java.sun.com/docs/books/tutorial/collections/index.html

2. If the date string comes in multiple formats, the simplest way to tackle this

is to have multiple SimpleDateFormat objects, and try each in turn:

http://java.sun.com/javase/6/docs/api/java/text/SimpleDateFormat.html

Problem, as they say, solved.

I was wondering what that tingling feeling at the back of my skull was...

Text like "July 09 2007 9:00 PM"?

java.text.SimpleDateFormat.parse()

No, the suggestion is to parse the java.lang.String to a java.util.Date.

Sorry, that was wrong of me. No Groovy should be posted in this thread.
