Constructors of Thread class

2. Thread ( String str )
3. Thread ( Runnable r )

You can create new thread, either by extending Thread class or by implementing Runnable interface. Thread class also defines many methods for managing threads. Some of them are,

Method	Description
setName()	to give thread a name
getName()	return thread's name
getPriority()	return thread's priority
isAlive()	checks if thread is still running or not

Some Important points to Remember

1. When we extend Thread class, we cannot override setName() and getName() functions, because they are declared final in Thread class.
2. While using sleep(), always handle the exception it throws.

   static void sleep(long milliseconds) throws InterruptedException
