Threads are lightweight execution units within a process that allow concurrent and parallel job execution. They enhance performance and responsiveness in programmed by enabling many sequences of instructions to run simultaneously.
Java uses various thread types, such as:
User Threads: The programme developer creates these, and users have control over them. User threads are maintained by the JVM and carry out specific tasks.
Daemon Threads: These are background threads that provide support to user threads., which are background threads. They are made to carry out background operations like garbage pickup, I/O operations, or other maintenance jobs. When all user threads have completed running, daemon threads are shut down.
