For example, the map-reduce pattern is based upon dividing a big problem into smaller one and processing them individually 4 To sever multiple clients at the same time.
Hope this information is helpful for you. You can also read about Multithreading in Java. To run diferent types of programs simultaneously. If threads are absent then the delay time and execution time of program will be long. Prasad 12 Oct To run several programs at a time. When a Java program starts, the JVM creates the main thread and calls the program's main method within that thread. Threads are use to perform asynchronous or background processing. Which is clearly a bad idea as you'll be Java is a multi-threaded programming language which means we can develop multi-threaded program using Java.
Multi-threading extends the idea of multitasking into applications where you can subdivide specific operations within a single application into individual threads. Each of the threads can run in parallel. Shivam 30 Jan for use multiple Inheritance. In Java there is a multithreading system. Other Related Discussions. Why we cannot override static method?

Since multiple threads access the same configuration file, it is essential to synchronize the threads , so only one thread at any time can be updating the configuration file.
While synchronization ensures consistency of the common resource in this case, the configuration file , it also introduces the possibility of delays in processing requests. Requests being processed by an application server must wait until the corresponding thread is allowed to enter the synchronized block. Excessive use of synchronized blocks can result in a high percentage of the processing time of a request being spent waiting for access to synchronized blocks of code.
To ensure great user experience, it is important to ensure that blocking due to thread synchronization is at a minimum. At the same time, it is also important to track the number of threads being spawned in the JVM.
If too many threads are created in parallel, the JVM memory must be sufficiently sized to handle this load. If not, application performance will suffer. Coding tutorials and news.

Thread class Thread class provides constructors and methods to create and perform operations on a thread.
JVM calls the run method on the thread. State getState : returns the state of the thread. Runnable interface The Runnable interface should be implemented by any class whose instances are intended to be executed by a thread.
Starting a thread start method of Thread class is used to start a newly created thread. A new thread starts with a new call stack. The thread moves from New state to the Runnable state. When the thread gets a chance to execute, its target run method will run.
