what exactly do you mean by 'delete the strings'?

you can simply assign null value to the variable string variable = ""; after the data has been merged.

do keep in mind though,
String a = "";
is not the same as:
String a = null;

Thanks for your reply.What I mean by delting is that I dont want these files in the folder after these files are merged to a single pdf merge12.


file1 = null;
file2 = null;

this has nothing to do with the String objects.
you should check out the delete method of the File class.

Hi Thanks for your reply.I have tried by assigning string file1 ="";
But its not working.

that's because manipulating a String object has nothing to do with what you try to do.
read my last post.

but the problem is that am storing these file names in a string.R u telling me to change this and store it in a file

no, I'm saying whether and how you have a filename stored has nothing to do with whether there (still) is a physical file on your hard drive.

Thanks a lot.I got now what u meant.I was able to delete the files after merging. Thank You stultuske
