MultiThreading in Java

Multi threading:-

It is light weight which is use in gaming

·         It executes multiple threads simultaneously at a time.

·         Thread is a light wait it takes small unit of time of processing.

·         Multithreading is a achieving of multitasking because of multithread share common memory area

·         They do not allocate separate memory to thread.

·         Context switch get less time to make processing them.

Multitasking types

1:- process based

2:- thread based

1:- process based multitasking:-

·         Each process has its own address in memory process allocate separate memory area .so it takes time to save process in memory area.

·         Cost of communication is high

·         Switch for one process to another then it take time to saving process in memory.

2:- Thread based multithreading:-

·         Thread have same address space

·         Cost communication is low

·         Thread is light weight.

Note: - each process required one thread.

Thread is light weight sub process it take separate path of execution it share separate area of memory execution

Life cycle of thread :-

1. New
2. Runnable
3. Running
4. Non-Runnable (Blocked)
5. Terminated
