Understanding Threads in Java
Threads in Java are a fundamental concept of concurrent programming, allowing multiple tasks to run simultaneously within a single program.
What is a Thread?
- A thread is a lightweight process that can run independently and concurrently within a Java application.
- It allows the program to perform multiple operations at once, enhancing performance and responsiveness, especially in applications that require multitasking.
Why is the Correct Answer 'B' (Class)?
- In Java, the Thread class is part of the `java.lang` package.
- It provides methods and properties to create and manage threads effectively.
- The Thread class is used to instantiate a thread object, which can be executed separately from the main thread.
Key Features of the Thread Class:
- Creating a Thread: You can create a thread by extending the Thread class or implementing the Runnable interface.
- Thread Lifecycle: The Thread class manages the lifecycle of a thread, which includes states such as New, Runnable, Blocked, Waiting, Timed Waiting, and Terminated.
- Thread Methods: The Thread class offers various methods, such as `start()`, `run()`, `sleep()`, and `join()`, to control thread execution.
Conclusion
- Since a thread in Java is represented by the Thread class, option 'B' is indeed the correct answer.
- Understanding how to use the Thread class is essential for developing highly efficient and responsive Java applications.
