Threads allow multiple activities to occur within a single process. Threads are lightweight processes that have their own call stack and can run concurrently with other threads. Threads take advantage of multiprocessor systems, simplify modeling, and allow for asynchronous background processing. The life cycle of a thread includes states such as new, runnable, running, blocked, and terminated. When first created, a thread is new, then becomes runnable when start() is called, running when scheduled, and blocked or terminated when completion criteria are met.

2. THREAD
• Threading is a facility to allow multiple activities to coexist within a
single process.
• Threads are sometimes referred to as lightweight processes. Like
processes, threads are independent, concurrent paths of execution
through a program, and each thread has its own stack.

3. Why use threads?
•Take advantage of multiprocessor systems
•Simplify modeling
•Perform asynchronous or background processing

4. Life cycle of a Thread (Thread States)
• The life cycle of the thread in java is controlled by JVM. The java
thread states are as follows:
• New
• Runnable
• Running
• Non-Runnable (Blocked)
• Terminated

6. Life cycle of a Thread
• 1) New
• The thread is in new state if you create an instance of Thread class
but before the invocation of start() method.
• 2) Runnable
• The thread is in runnable state after invocation of start() method, but
the thread scheduler has not selected it to be the running thread.
• 3) Running
• The thread is in running state if the thread scheduler has selected it.

7. Life cycle of a Thread
• 4) Non-Runnable (Blocked)
• This is the state when the thread is still alive, but is currently not
eligible to run.
• 5) Terminated
• A thread is in terminated or dead state when its run() method exits.
