Java zip compression optimized version resolves files that have been consumed after compression cannot be deleted

The recent zip operation, from the Internet to find a processing method, but after the test there are some bugs, the main problem is the declaration of file flow, causing the JVM to occupy the file and not release, specifically to make their own changes issued, has been recorded
