How to use if/else in tMap

[JM39]

hello, I've had a look around and can't find the answer to my specific issue.  

I have some source data where one of the columns contains a number which can typically be either one, two or three characters.  In the output I want all those values to be six characters long.  So if the source contains two, I want to add four leading zeros, if the source contains three, I want to add three leading zeros, etc.  I'm not sure how to do this?

Hi
Take a look at this topic, it provides Java expression to do it.
