You can define and instantiate a thread in one of two ways:
• Extend the java.lang.Thread class.
• Implement the Runnable interface.
Ex:
class MyFirstThread extends Thread {
public void run() {
System.out.println("Important job running in MyFirstThread");
}
}
class MyFirstRunnableClass implements Runnable {
public void run() {
System.out.println("Imp job running in MyFirstRunnableClass");
}
}

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.
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?
Can you restart stopped thread in java?
No. Once a thread is stopped you cannot restart it.
What is the use of thread in java?

How you make shared and synchronized variable in java thread?

What are the two ways of spawning a thread in Java?

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 daemon thread in java?
Daemon thread is a kind of thread that does not prevent the JVM from exiting when the thread is still running while the program finishes. A good example of this is the garbage collection.

Difference between Java threads and user level thread?
A Java thread can be considered as similar to a user level thread. Let us say you are running a web browser, windows media player and GTalk for chat simultaneously - Actually the operating system is running an individual thread for each of these apps which gives you a seamless feeling of things running in parallel. Similarly Java Threads are features in the Java programming language that allow you to run multiple JVM tasks in parallel.
How do you call start method into run method?
In Java a Thread object has two methods that the programmer needs to know: start and run.run is where we put the code that we want to execute when the Thread begins.The start method is what tells the Java Virtual Machine that it should create a new thread and tell it to execute its run method.While you can make a call to thread.run() in order to execute the code in the run method, this will not actually make a new thread in the JVM, but will execute just like any normal method call.
