Describe the Life cycle of a thread in java.?
Life cycle of a thread New: when a thread is not yet initialized, it is in New state Runnable or Ready : Once the thread is initialized and its start method is called, then the thread becomes ready for execution, which is otherwise called runnable or ready state Not Runnable : When a thread is asked to sleep for some time or wait for some time by using the sleep or wait method, thread goes to Not Runnable state for the specified time. Dead state: Once the thread is executed,it turns to dead state. Hope this would answer your question. let me know if you are still not clear
In relation to Java what is a thread?
A Java Thread is a thread of execution in a Java Program. A Java Virtual Machine can have a single application running multiple threads, which is known as concurrency. Threads are what make the program run. Each thread has a different priority, and when the machine queue fills up, the threads are executed in the order of their priority.
Can you restart stopped thread in java?
No. Once a thread is stopped you cannot restart it.
About a threads life cycle?
A Thread has many states in its life cycle. 1. Active - When you create a new thread 2. Running - When you invoke the thread.start() method 3. Waiting - When it is waiting on user input or for some other thread 4. Terminated/Dead - Once it finishes execution.

What are the factors affecting product life cycle?
Factors that affects the life cycle of a product depends on the product in question. A car tire as an example of a product has its lice spam and this is determined through the pattern of its life cycle. Factors that affects the life cycle of a car tire basically are four, and they are- Pattern of the thread on the tire, depth of the thread on the tire, nature of the road on which the car is been driven on, and the style of driving the car. these are the chief factors responsible for your tires long or short life and they affect the product life cycle.
How you would achieve multithreading in java?
Java provides built-in support for multithreaded programming. A multithreaded program contains two or more parts that can run concurrently. Each part of such a program is called a thread, and each thread defines a separate path of execution.A multithreading is a specialized form of multitasking. Multitasking threads require less overhead than multitasking processes.We achieve multithreading in Java by following this steps...New: A new thread begins its life cycle in the new state. It remains in this state until the program starts the thread. It is also referred to as a born thread.Runnable: After a newly born thread is started, the thread becomes runnable. A thread in this state is considered to be executing its task.Waiting: Sometimes a thread transitions to the waiting state while the thread waits for another thread to perform a task. A thread transitions back to the runnable state only when another thread signals the waiting thread to continue executing.Timed waiting: A runnable thread can enter the timed waiting state for a specified interval of time. A thread in this state transitions back to the runnable state when that time interval expires or when the event it is waiting for occurs.Terminated: A runnable thread enters the terminated state when it completes its task or otherwise terminates.
What is inline thread in java?
You can start a thread "inline" without implementing Runnable or extending Thread class( new Thread() { public void run(){// do something} } ).start();
What is the default priority of background thread in java?
Medium priority
Multithreading in java?
I am assuming that you want to know how to multithread in Java. 1) Write a class that implements Runnable. Put just the method run() in it. 2) Inside the run() method, put the code that you want your thread to run. 3) Instantiate the class (example: Runnable runnable = new MyRunnable();) 4) Make a new Thread (example: Thread thread = new Thread(runnable, <the name of your thread(optional)>); 5) Start the thread (example: thread.start();) 6) That's it! Your thread is now running. PS. Check the Java API for more information. Did that answer your question?
