That is additionally a really well-liked thread interview questions and many of the interviewer is actually to know what’s your perspective whereas selecting Thread vs Runnable or the other.
On this java article, we are going to attempt to level out some variations between Thread and Runnable in Java which can assist you to make an knowledgeable resolution.
Btw, if you’re critical about mastering Java multi-threading and concurrency then I additionally recommend you check out these Java Multithreading programs. This listing comprises superior programs to develop into an skilled in Multithreading, concurrency, and Parallel programming in Java with a powerful emphasis on excessive efficiency.
Distinction between Thread and Runnable interface in Java
Here are a few of my ideas on whether or not I ought to use Thread or Runnable for implementing duties in Java, although you’ve one other selection as “Callable” for implementing thread which we are going to focus on later.
2. In Object-oriented programming extending a category usually means including new performance, modifying, or enhancing behaviors. If we don’t make any modifications on Thread then use the Runnable interface as an alternative.
3. The Runnable interface represents a Activity that may be executed by both plain Thread or Executors or another means. so logical separation of Activity as Runnable than Thread is an effective design resolution.
4. Separating process as Runnable means we will reuse the duty and in addition has the freedom to execute it from completely different means. since you cannot restart a Thread as soon as it completes. once more Runnable vs Thread for a process, Runnable is the winner.
5. Java designer acknowledges this and that is why Executors settle for Runnable as Activity they usually have employee thread which executes these process.
6. Inheriting all Thread strategies are a further overhead only for representing a Activity that may be executed simply with Runnable.
And, should you prefer to see the distinction in tabular format, here’s a good desk which reveals the important variations between Thread class and Runnable interface in Java:
These have been among the notable variations between Thread and Runnable in Java if you realize another variations on Thread vs Runnable than please share them through feedback. I personally use Runnable over Thread for this situation and advocate utilizing the Runnable or Callable interface based mostly in your requirement.Some extra Java Tutorials you could like
