Which is the correct way to start a new thread?
To use the Runnable interface to create and start a thread, you have to do the following:
- Create a class that implements Runnable.
- Provide a run method in the Runnable class.
- Create an instance of the Thread class and pass your Runnable object to its constructor as a parameter.
- Call the Thread object’s start method.
What does it mean to start a thread?
Java Thread start() method The start() method of thread class is used to begin the execution of thread. The result of this method is two threads that are running concurrently: the current thread (which returns from the call to the start method) and the other thread (which executes its run method).
How do we start and stop a thread?
// Create your Runnable instance Task task = new Task(…); // Start a thread and run your Runnable Thread t = new Thread(task); To stop it, have a method on your Task instance that sets a flag to tell the run method to exit; returning from run exits the thread.
What is suitable to start a thread?
Explanation: Option C is suitable to start a thread.
How do you implement a thread?
You can create threads by implementing the runnable interface and overriding the run() method. Then, you can create a thread object and call the start() method. Thread Class: The Thread class provides constructors and methods for creating and operating on threads.
How thread start calls run method?
If you call start() method on Thread, Java Virtual Machine will call run() method and two threads will run concurrently now – Current Thread and Other Thread or Runnable implementation. /** * Causes this thread to begin execution; the Java Virtual Machine * calls the run method of this thread.
What is the difference between run and start in thread?
start method of thread class is implemented as when it is called a new Thread is created and code inside run() method is executed in that new Thread. While if run method is executed directly than no new Thread is created and code inside run() will execute on current Thread and no multi-threading will take place.
Can we restart a thread in Java?
Since a Thread can not be restarted you have to create a new Thread everytime. A better practice is to separate the code to run in a thread from a Thread ‘s lifecycle by using the Runnable interface. Just extract the run method in a class that implements Runnable . Then you can easily restart it.

What is the difference between starting thread with run and start method?
So what is the difference between the start and run method? Main difference is that when program calls start() method a new Thread is created and code inside run() method is executed in new Thread while if you call run() method directly no new Thread is created and code inside run() will execute on current Thread.
Which two options allow you to create threads?
There are two ways to create a thread:
- extends Thread class.
- implement Runnable interface.
How do I post or start a new thread?

What happens if you don’t create a new thread in Java?
If you don’t start () it, nothing will happen – creating a Thread doesn’t execute it. If you don’t join) it, your main thread may finish and exit and the whole program exit before the other thread has been scheduled to execute. It’s indeterminate whether it runs or not if you don’t join it.
When does the thread start in thread.start?
The thread begins executing at the first line of the method represented by the ThreadStart or ParameterizedThreadStart delegate supplied to the thread constructor. Note that the call to Start does not block the calling thread.
What’s the difference between start-threadjob and start-job cmdlet?
Start-ThreadJob creates background jobs similar to the Start-Job cmdlet. The main difference is that the jobs which are created run in separate threads within the local process. By default, the jobs use the current working directory of the caller that started the job.
