Multithreading in Java is a feature that allows you to run multiple parts of a program concurrently, which can improve the performance and efficiency of your application. A thread is a lightweight sub-process that shares the same memory space with other threads. You can create threads in Java by either extending the Thread class or implementing the Runnable interface. Both methods require you to override the run() method, which defines the actions of the thread. You can also use some methods from the Thread class to control the behavior and priority of the threads, such as start(), sleep(), join(), getPriority(), and setPriority().
Some of the advantages of multithreading in Java are:
- - It does not block the user interface, as threads can perform tasks in the background.
- - It can utilize the CPU resources better, as multiple threads can run on multiple cores or processors.
- - It can handle multiple requests or events simultaneously, which is useful for server-side applications or event-driven programming.
- - It can increase the responsiveness and interactivity of the application, as threads can communicate with each other using shared variables or synchronization mechanisms.
