suresh What is a Thread in Java and how is it different from a process?
In Java, a Thread is a unit of execution that can run concurrently with other threads in a Java program. Threads are used to perform multiple tasks at the same time, allowing for parallel processing and improved performance.
On the other hand, a process in Java is an independent program that has its own memory space, file handles, and other system resources. Processes do not share memory or resources with each other, unlike threads which can share resources within the same process.
Threads are lightweight compared to processes, as they share the same memory space and resources of the process they belong to. This makes threads more efficient for multitasking and parallel computing in Java applications.
Overall, threads in Java provide a way to achieve concurrency and multi-tasking within a single process, while processes are separate entities that run independently of each other.
