File fileName = new File("fileA");

How can I snappy compress this file and get the file name of the compressed file?

You can use this library: Snappy for java

First read the file to a String, then compress it:

String input = FileUtils.readFileToByteArray(new File("fileA"));

byte[] compressed = Snappy.compress(input.getBytes("UTF-8"));

String result = new String(uncompressed, "UTF-8");

Finally write it to a file of your choice:

FileUtils.writeStringToFile(new File("targetFile"),result,"UTF-8")

I have used Apache Common FileUtils for brevity here.
