Multithreaded Programming, Part One
Let s examine this program in detail The program creates three classes The first is SumArray It defines the method SumIt( ), which sums an integer array The second class is MyThread, which uses a static object called sa that is of type SumArray Thus, only one object of SumArray is shared by all objects of type MyThread This object is used to obtain the sum of an integer array Notice that SumArray stores the running total in a field called sum Thus, if two threads use SumIt( ) concurrently, both will be attempting to use sum to hold the running total Because this will cause errors, access to SumIt( ) must be synchronized Finally, the class Sync creates two threads and has them compute the sum of an integer array Inside SumIt( ), the lock statement prevents simultaneous use of the method by different threads Notice that lock uses lockOn as the object being synchronized This is a private object that is used solely for synchronization Sleep( ) is called to purposely allow a task-switch to occur, if one can but it can t in this case Because the code within SumIt( ) is locked, it can be used by only one thread at a time Thus, when the second child thread begins execution, it does not enter SumIt( ) until after the first child thread is done with it This ensures the correct result is produced To understand the effects of lock fully, try removing it from the body of SumIt( ) After doing this, SumIt( ) is no longer synchronized, and any number of threads can use it concurrently on the same object The problem with this is that the running total is stored in sum, which will be changed by each thread that calls SumIt( ) Thus, when two threads call SumIt( ) at the same time on the same object, incorrect results are produced because sum reflects the summation of both threads, mixed together For example, here is sample output from the program after lock has been removed from SumIt( ):
