Threads are used in Java to run multiple operations in parallel. You can create and run multiple threads in parallel to utilize the processing power of the computer and reduce waiting time which would be high if processes are executed in sequence
Thread is a single sequential flow of control within program. Each flow of control may be thought of as a seperate lines of code(module) is called as thread.Actually thread is a predefined class in java. threads are used to handle Exceptions in java.
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.
No. Once a thread is stopped you cannot restart it.
You can create a Thread in Java by using two ways. 1. Extending the Thread class public class Test extends Thread { ..... } 2. Implementing the Runnable Interface public class Test implements Runnable { ... }
The notify() method is used in Thread Communication between two threads along with the wait() method
You can start a thread "inline" without implementing Runnable or extending Thread class( new Thread() { public void run(){// do something} } ).start();
Medium priority
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?
Green thread scheduled by jvm insteadof respective operating system(nativiely).
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.
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.
It is used to alert the compiler that the value of a variable may be modified by more than one thread. As a result, the Java Virtual Machine is not allowed to do certain optimizations, which are problematic in such cases.
