I have to submit an XML file in Perforce Server. The value of an XML tag can be formed in any language like English, Japanese, Chinese etc. But when I add Japanese or Chinese language then the file type becomes binary instead of text. That's because the Perforce Server identifies binary and text files based on whether it detects non-text characters in the first 8192 bytes of the file.
After studying, I knew that there is a term called p4 typemap which can be used to override the default logic of auto detection of file type.

But the problem is that this solution is from p4v and terminal based but i want to know is there any way to do this programmatically?
You don't necessarily need a typemap to do this; you can also specify a filetype as a parameter to the p4 add command, e.g.:
p4 add -t binary blahblah.xml
If you have some XML files that are Unicode/binary and some that are ASCII, it makes more sense to specify this on a per-file basis rather than trying to capture it in a typemap. The typemap is meant to be set up ahead of time by the admin to represent common overrides, not modified on the fly by applications.
To convert p4 commands/options into Java code, see the P4 Java API doc:
