Java Thread Class and Runnable Interface

 There are two ways to create a thread:

1. By extending Thread class
2. By implementing Runnable interface.

 Thread class:

 

Thread class provide constructors and methods to create and perform operations on a thread.Thread class extends Object class and implements Runnable interface.   Methods of Thread class:   1.    public void run(): is used to perform action for a thread. 2.    public void start(): starts the execution of the thread.JVM calls the run() method on the thread. 3.    public void sleep(long miliseconds): Causes the currently executing thread to sleep (temporarily cease execution) for the specified number of milliseconds. 4.    public void join(): waits for a thread to die. 5.    public void join(long miliseconds): waits for a thread to die for the specified miliseconds. 6.    public int getPriority(): returns the priority of the thread. 7.    public int setPriority(int priority): changes the priority of the thread. 8.    public String getName(): returns the name of the thread. 9.    public void setName(String name): changes the name of the thread. 10. public Thread currentThread(): returns the reference of currently executing thread. 11. public int getId(): returns the id of the thread. 12. public Thread.State getState(): returns the state of the thread. 13. public boolean isAlive(): tests if the thread is alive. 14. public void yield(): causes the currently executing thread object to temporarily pause and allow other threads to execute. 15. public void suspend(): is used to suspend the thread(depricated). 16. public void resume(): is used to resume the suspended thread(depricated). 17. public void stop(): is used to stop the thread(depricated). 18. public boolean isDaemon(): tests if the thread is a daemon thread. 19. public void setDaemon(boolean b): marks the thread as daemon or user thread. 20. public void interrupt(): interrupts the thread. 21. public boolean isInterrupted(): tests if the thread has been interrupted. 22. public static boolean interrupted(): tests if the current thread has been interrupted Runnable interface:   The Runnable interface should be implemented by any class whose instances are intended to be executed by a thread. Runnable interface have only one method named run(). 1.    public void run(): is used to perform action for a thread. 2.   start() method of Thread class is used to start a newly created thread.
