That is additionally a really fashionable thread interview questions and many of the interviewer is basically to know what’s your standpoint whereas selecting Thread vs Runnable or the alternative.
On this java article, we are going to attempt to level out some variations between Thread and Runnable in Java which can aid you to make an knowledgeable choice.
Btw, if you’re critical about mastering Java multi-threading and concurrency then I additionally recommend you check out these Java Multithreading programs. This checklist comprises superior programs to turn out to be an professional in Multithreading, concurrency, and Parallel programming in Java with a robust 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 have got one other selection as “Callable” for implementing thread which we are going to talk about later.
2. In Object-oriented programming extending a category typically means including new performance, modifying, or enhancing behaviors. If we do not 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 every other means. so logical separation of Activity as Runnable than Thread is an effective design choice.
4. Separating activity as Runnable means we will reuse the duty and in addition has the freedom to execute it from totally different means. since you can’t restart a Thread as soon as it completes. once more Runnable vs Thread for a activity, Runnable is the winner.
5. Java designer acknowledges this and that is why Executors settle for Runnable as Activity and so they have employee thread which executes these activity.
6. Inheriting all Thread strategies are an extra overhead only for representing a Activity that may be carried out simply with Runnable.
And, should you wish to see the distinction in tabular format, here’s a good desk which exhibits 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 recognize every other variations on Thread vs Runnable than please share them by way of feedback. I personally use Runnable over Thread for this state of affairs and suggest utilizing the Runnable or Callable interface primarily based in your requirement.Some extra Java Tutorials you could like
