What are the differences between Thread and Runnable in Java?

In Java, a Thread is a class that represents a thread of execution, while Runnable is an interface that defines a task to be executed. You can extend the Thread class or implement the Runnable interface to create a thread.

Can you explain when to use Runnable instead of Thread?

You should use Runnable when you want to separate the task from the thread execution. This allows for more flexibility, such as passing the same Runnable instance to multiple threads.

What are the advantages of using Runnable?

Using Runnable allows for better resource management, as it can be reused by multiple threads. It also promotes a cleaner design by separating the task from the thread.

Are there any performance differences between using Thread and Runnable?

Generally, there are no significant performance differences. However, using Runnable can lead to better performance in scenarios where you need to share the same task among multiple threads.
