Java's standard IO classes all thread-safe. This means there's a lot of synchronized protection in these IO classes. If the classes are used in a single thread environment , the synchronization protection is unneeded and reduces performance. For this reason, a set of unsynchronized IO classes has been added
These classes work in the same manner as the standard IO classes but are not thread safe.
Where applicable, the standard IO classes has been replaced the the unsync IO classes.
