What happens to any thread after the main program ends?

As already stated, any thread, whether detached or not, will die with its process on most OSes. The process itself can be terminated by raising a signal, by calling exit() or by returning from the main function.

Which thread will execute first?

Output explanation: Thread with the highest priority will get an execution chance prior to other threads. Suppose there are 3 threads t1, t2, and t3 with priorities 4, 6, and 1. So, thread t2 will execute first based on maximum priority 6 after that t1 will execute and then t3.

Do threads execute in order?

The whole point of threads is that they can be executed concurrently. If you want to ensure specific order in which things are done, you either have to move away from using threads, or use explicit synchronization.

Is main thread a user thread?

Any thread inherits the daemon status of the thread that created it. Since the main thread is a user thread, any thread that is created inside the main method is by default a user thread.

How do you prioritize a thread?

Why are threads assigned priorities?

Thread priority in Java is a number assigned to a thread that is used by Thread scheduler to decide which thread should be allowed to execute. In Java, each thread is assigned a different priority that will decide the order (preference) in which it is scheduled for running.

How are threads executed?

2 Answers. Threads, by their nature, are concurrent to each other. This means, that two (or more) threads compete for the same resource (CPU) when they are executed at the same time, and CPU switches itself from executing one to another in a random-to-you (unpredictable) order.

How do you execute a thread?

If the class extends the Thread class, the thread can be run by creating an instance of the class and call its start() method:

1. Extend Example. public class Main extends Thread { public static void main(String[] args) { Main thread = new Main(); thread.
2. Implement Example.
3. Example.
4. Example.

What is the priority of main thread?

The default priority of Main thread is 5 and for all remaining user threads priority will be inherited from parent to child.

What happens when thread dies?

A thread dies naturally when its run() method exits normally. For example, the while loop in this method is a finite loop–it will iterate 100 times and then exit. A thread with this run() method will die naturally after the loop and the run() method completes. Thread myThread = new MyThreadClass(); myThread.
