The difference between synchronous code block and synchronous method: Synchronous code block can pass in arbitrary object, synchronous method if more than one thread examines a new object, different synchronization locks are not exclusive to different threads, cannot realize thread synchronization effect, then thread synchronization fails.The difference between the two is mainly reflected in the synchronization lock above. For the synchronization meth
