Parallelism

Parallel computing is an important concept that describes the use of creating a set of smaller problems in order to quickly process a larger program. This option is essential in speeding up the overall process by allowing its different elements to get processed at the same time. Parallel computing has especially found more power, as all JVMs now have access to multiple processors.

The Java framework essentially takes the advantage of parallelism and implements it into all of its functionalities, including garbage collection. However, this means that you have to partition your programs, functions, and memory objects in order to run them in a parallel operation. The Java runtime usually performs the actual partitioning and the recombining of these divisions to create the final output.

Parallelism is difficult to implement in JVM where collections are employed. Collections...
