Multithreading in Java

Thread is a light-weight process. Process unit is known as thread.

When a process is divided into multiple parts and each part can be executed independently, then it is known as multi-threading or multi-tasking. Multithreading is very suitable for game and network applications.

Multithreading

Multithreading is a Java feature that allows concurrent execution of two or more parts of a program for maximum utilization of CPU. Each part of such a program is called a thread. So, threads are light-weight processes within a process

Thread is a predefined class prsent in java.lang package.

This class is responsible to create and manupulate the thread.

class Test

{

    static void fact() throws Exception{

        System.out.println(Thread.currentThread().getname());

        System.out.println("fact()….");

        Thread.sleep(5000);

        System.out.println("………..");

        public static void main(String[] args) throws Exception 

        {

            System.out.println(Thread.currentThread().getname());

            System.out.println("hello");

            fact();

            System.out.println("hi");

            reverse();

            System.out.println("now i am in main");

        }

        static void reverse()throws Exception

        {

            System.out.println(Thread.currentThread().getname());

            System.out.println("reverse()…");

            Thread.sleep(3000);

            System.out.println("………….");

        }

    }

Following  are the predefined members which are generally used to create and manupulate the thread.

CONSTRUCTOR:-

Thread( String Thread_name)

Thread(Runable object)

Thread(Runable object, String Thread_name)

Methods :-

Static Thread() – It returns the object of current running thread.

String getName()- It returns the name of Thread.

Void setName (string Thread_name) – Assign a name of thread.

Int get priorit()- Returns the priority of thread.

Void setPriority():-Assign a priority to thread.

Void start():- To active the thread. It is responsible to devide process into multiple part.

Void run():- This method contaions the logic of thread .

Void sleep (long millisec):- This method block the thread for a specifi period of time.

Void suspend():-Block the thread until resume () called.

Void resume():- Reactive the suspended thread.

Void join():- Block the Thread until notify() or notify all() called.

Void stop():- move the thread to dead seat.

Boolean isalive():- check the thread exstance live or dead.
