The concept of multithreaded programming origins from the word thread, and since multiple threads exist, hence, multithreading is possible. So for this, you must have to know what threads are. Almost all OS supports the concept of threads. A thread can be considered as the path taken for the execution of a program. By default, Java has one thread always running which is the main() thread, and it is created purposefully by the JVM only.
In other words, you can define thread as multiple tasks coexist simultaneously in a single process. Java threads are also termed as light-weight processes.
Threads are advantageous because of the following characteristics:
- It helps a program utilize the multiprocessor systems.
- Helps in simplifying the modeling.
- Also creates your UI more responsive.
- Makes your program in performing asynchronous background tasks
