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, and context-switching between the threads takes less time than process. Java Multithreading is mostly used in games, animation, etc.

Advantages of Java Multithreading

• It doesn't block the user because threads are independent and you can perform multiple operations at the same time.
• You can perform many operations together, so it saves time.
• Threads are independent, so it doesn't affect other threads if an exception occurs in a single thread.
