Trying to get Left or Right Values

[gibboda]

I am trying to duplicate an if statement that was done in our VB
program in Java Program. I have search the groups and the web trying
to get an understanding of doing it in java but have failed.

The VB statement is:

If Left(value,4) = "LIST" Then

(Do some programming logic)

End if

Thank you for your advice and any input where to look for information.

If value is a string then you can use
value.substring(0, 4)
to extract the leftmost 4 characters

(and similarly with endsWith)
