Multithreading in java , Java Multithreading

 Multithreading in java is a process of executing multiple threads simultaneously.A thread is a lightweight sub-process, the smallest unit of processing. Multiprocessing and multithreading, both are used to achieve multitasking.

 

However, we use multithreading than multiprocessing because threads use a shared memory area. They don't allocate separate memory area so saves memory. Java Multithreading is mostly used in games, animation, etc.

   Advantages of Java Multithreading

 

1) It doesn't block the user because threads are independent and you can perform multiple operations at the same time.

 

2) You can perform many operations together, so it saves time.

 

3) Threads are independent, so it doesn't affect other threads if an exception occurs in a single thread.

What is Thread in java

 

A thread is a lightweight subprocess, the smallest unit of processing. It is a separate path of execution.

 

Threads are independent. If there occurs exception in one thread, it doesn't affect other threads. It uses a shared memory area.

Java Thread class

 

Java provides Thread class to achieve thread programming. Thread class provides constructors and methods to create and perform operations on a thread. Thread class extends Object class and implements Runnable interface.
