Separate read and write Synchronization

For many data structures, it is possible to allow multiple reads to occur in parallel, but reads cannot be safely performed while a write is in progress and it is not safe to allow multiple writes simultaneously. Rewrite the Java LinkedCell class  given in this chapter to allow multiple simultaneous reads, but prevent reads and writes while a write is in progress. You may want to use more than one lock. For example, you could assume objects called ReadLock and WriteLock and use synchronized statements involving these two objects. Explain your approach  and  why  it works.
