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. ... Java Multithreading is mostly used in games, animation, etc.
The main purpose of multithreading is to provide simultaneous execution of two or more parts of a program to maximum utilize the CPU time. A multithreaded program contains two or more parts that can run concurrently. Each such part of a program called thread.
Benefits of Multithreading*
Improved throughput.
Simultaneous and fully symmetric use of multiple processors for computation and I/O.
Superior application responsiveness.
Improved server responsiveness.
Minimized system resource usage.
Program structure simplification.
Better communication.
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.
