I develop a file import process in database My files are composed of lines, and each field is separated by a tab.

So I use the java split function:

String[] thisLine = line.split("\\t");

I have a problem when my last field is empty, so that my line ends with a tab, and then a line break.

Example

JFJ[TAB]ge[TAB]10400004V[TAB]31.1[TAB]0[TAB]0[TAB]0[TAB][TAB]90[TAB]

The split function does not return the last field. In this case, the split function return 9 fi

have you a solution?

Not very clear what you want the split to return here. Based on your code, the last field of the array will be `90`. Isn't that what you want? Or are you bothered by the empty field created by the two consecutive tabs? – Mena Aug 23 '18 at 13:40

@Mena looks like OP expects `split` to return one more empty element after 90 – Ivan Aug 23 '18 at 13:42

Use `split("\t", -1)`. Now where is that duplicate explaining it... – Pshemo Aug 23 '18 at 13:43
@Pshemo was about to comment the exact same thing, but I'd wait to close as dupe until OP clarifies. – Mena Aug 23 '18 at 13:44
@Mena I need empty value after lest tab – user1450740 Aug 23 '18 at 13:45
@Pshemo and Ivan looks like you were right. – Mena Aug 23 '18 at 13:46
@Pshemo Thanks !! – user1450740 Aug 23 '18 at 13:47
