Which is better implementing runnable or extending Thread?

There is no chance of extending any other class. In the second approach, while implementing Runnable interface we can extends any other class. Hence we are able to use the benefits of Inheritance. Because of the above reasons, implementing Runnable interface approach is recommended than extending Thread class.

When should we create Thread by implementing runnable and extending Thread class?

One must extend a Thread class only if it has to override or specialise some other methods of Thread class. You must implement a Runnable interface if you only want to specialise run method only.

What is the difference between extend Thread class and implement runnable interface?

There are many reasons to prefer Runnable over Thread . Some of them are as below: Java does not support multiple inheritance. Hence if your class had already extended some another class, it can not extend Thread class anymore.

Can we extend Thread and implement runnable at the same time?

1 Answer. You should almost never do that. The type Thread already implements Runnable . The only reason to do this is if you want to be explicit in your source code.

Why is it better to implement runnable interface while creating threads?

5 Answers. When you extend Thread class, you can’t extend any other class which you require. (As you know, Java does not allow inheriting more than one class). When you implement Runnable, you can save a space for your class to extend any other class in future or now.

Why is the runnable interface preferred over extending Thread?

– Runnable interface is always preferred because, the class implementing it can implement as many interfaces as a developer can, and also extend another class. – Whereas extending the Thread class, it can not extend another class, as Java supports only single inheritance.

Which way of creating Thread is better?

That means composition is the better way to go. Java only supports single inheritance, so you can only extend one class. Instantiating an interface gives a cleaner separation between your code and the implementation of threads. Implementing Runnable makes your class more flexible.

Why do we prefer runnable interface in Java?

What are the advantages of runnable over extending the thread class for multithreading?

When you extend Thread class, you can’t extend any other class which you require. (As you know, Java does not allow inheriting more than one class). When you implement Runnable, you can save a space for your class to extend any other class in future or now.

Which is better way to create a Thread?

There are two ways to create a thread:

1. Extends Thread class. Create a thread by a new class that extends Thread class and create an instance of that class.
2. Implementing the Runnable Interface. The easiest way to create a thread is to create a class that implements the runnable interface.

Why does Java have two ways to create child threads by extending Thread or implementing runnable and which approach is better?

Java threads can be created graciously in two ways: implementing the Runnable interface and extending Thread class. In this process only one class can be inherited from the parent class Thread. Implementing Runnable interface overcomes the limitation of inheriting from only one parent class Thread.

What is the difference between extending thread class and implementing Runnable interface?

The significant differences between extending Thread class and implementing Runnable interface: 1 When we extend Thread class, we can’t extend any other class even we require and When we implement Runnable, we can save… 2 When we extend Thread class, each of our thread creates unique object and associate with it. When we implements… More

Should I extend Thread or runnable in Java?

When you extend Thread class, you can’t extend any other class which you require. (As you know, Java does not allow inheriting more than one class). When you implement Runnable, you can save a space for your class to extend any other class in future or now.

What are the advantages of threading in Java?

You will learn from proficient Java programmers how to create a thread using Extends Thread class and Implements Runnable interface. Reduces development time. Reduces maintenance costs. Improves the performance of complex applications. Useful for improving the responsiveness of the user interfaces.

What are the advantages of using runnable interface in Java?

Another thing, Since Java does not support multiple inheritance, if you implement the Runnable you’ll avoid problems of multiple extending, so if you implement Runnable interface you can extend any class that you are required other than Thread class. A class may only have one superclass, but may implement any number of interfaces.
