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.

Which one is better way to create a thread?

There are two ways to create a thread:

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

Which method is best for threading in Java?

Thread must be implemented by Implementing Runnable Interface. As Java does not support Multiple Inheritance (1 class cannot be inherited from 2 super class). For eg: class A extends B,Thread — This cannot be achieved in java but can be done in C++. But Multiple Inheritance can be achieved in java by using Interface.

How do we create a thread extends Thread implements runnable which is better and why?

This subclass should override the run method of the Thread class. An instance of the subclass can then be allocated and started. The other way to create a thread is to declare a class that implements the Runnable interface. That class then implements the run method.

What is the difference between Thread class and runnable interface?

Runnable is an interface which represents a task that could be executed by either a Thread or Executor or some similar means. On the other hand, Thread is a class which creates a new thread. Implementing the Runnable interface doesn’t create a new thread. Java Docs clearly explains the difference between them.

When we extend Thread class each of our Thread creates unique object and associate with it when we implements runnable it shares the same object to multiple threads?

When we extend Thread class, each thread creates unique objects of thread class. For example, if you create 5 threads, we have 5 different objects in the memory. When we implement Runnable interface, then we create only one object the thread class. And the same object we pass to multiple threads.

How do you create a thread by extending the thread class explain with an example program?

1) Java Thread Example by extending Thread class

1. class Multi extends Thread{
2. public void run(){
3. System.out.println(“thread is running…”);
4. }
5. public static void main(String args[]){
6. Multi t1=new Multi();
7. t1.start();
8. }

Which of the following are the step to create thread by extending Thread class?

By extending the Thread class….Following are the steps for creating a program of the thread pool

• create a runnable object to execute.
• using executors create an executor pool.
• Now Pass the object to the executor pool.
• At last shutdown the executor pool.

When a class extends the Thread class it should override which method of thread class to start the thread?

run method
One is to declare a class to be a subclass of Thread . This subclass should override the run method of class Thread . An instance of the subclass can then be allocated and started.

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.

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.

How do you create a Thread by extending the Thread class explain with an example program?

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

Why do we use runnable instead of thread?

Simply put, we generally encourage the use of Runnable over Thread: When extending the Thread class, we’re not overriding any of its methods. Instead, we override the method of Runnable ( which Thread happens to implement). This is a clear violation of IS-A Thread principle

What happens when we extend Thread class in Java?

When we extend Thread class, each thread creates unique objects of thread class. For example, if you create 5 threads, we have 5 different objects in the memory. When we implement Runnable interface, then we create only one object the thread class. And the same object we pass to multiple threads.

How to create a new thread of execution in Java?

There are two ways to create a new thread of execution. One is to declare a class to be a subclass of Thread; The other way to create a thread is to declare a class that implements the Runnable interface. Thread class provides constructors and methods to create and perform operations on a thread class.
