Abstract

In this paper we have discussed one of the greatest features of the general purpose computer programming language –Java. This paper represents concepts of Synchronization possibilities and features in Java. Today's operating systems support concept of "Multitasking". Multitasking achieved by executing more than one task at a same time. Tasks runs on threads. Multitasking runs more than one task at a same time. Multitasking which means doing many things at the same time is one of the most fundamental concepts in computer engineering and computer science because the processor execute given tasks in parallel so it makes me think that are executing simultaneously. Multitasking is related to other fundamental concepts like processes and threads. A process is a computer program that is executing in a processor, while a thread is a part of a process that has a way of execution: it is a thread of execution. Every process has at least one thread of execution. There are two types of multitasking: process – based and thread – based. Process-based multitasking, means that on a given computer there can be more than one program or process that is executing, while thread-based multitasking, which is also known as multithreading, means that within a process, there can be more than one thread of execution, each of them doing a job and so accomplishing the job of their process. When there are many processes or many threads within processes, they may have to cooperate with each other or concurrently try to get access to some shared computer resources like: processor, memory and input/output devices. They may have to, for example: print a file in a printer or write and/or read to the same file. We need a way of setting an order, where processes and/or threads could do their jobs (user jobs) without any problem, we need to synchronize them. Java has built-in support for process and thread synchronization, there are some constructs that we can use when we need to do synchronization.This paper, a first phase discussed the concept of Parall Programming, threads, how to create a thread, using a thread, working with more than one thread. Second phase is about synchronization, what is in general and in the end we disscused the synchronization possibilities and feautures in Java.
