Each thread is associated with an instance of the Thread class. There are three main ways to define and start a thread: provide a Runnable object, subclass Thread, or use an Executor interface. The Runnable interface represents a task that can be executed by a thread and defines a run method with no arguments. Starting the thread causes the run method to be called in a separately executing thread. Runnable objects are more general than subclassing Thread because they can implement interfaces other than Thread. However, subclassing Thread is easier for simple applications. The Executor interface provides a way to decouple task submission from how the tasks are scheduled and run. Thread.sleep causes the current thread to suspend execution for a specified period,

This session discusses about the basic building blocks of Concurrent Programming in Java, which include:
synchronisation part 2, synchronized methods, intrinsic locks, atomic access, liveness, deadlock, starvation, livelock, guarded blocks, immutable objects, synchronized class example, strategy for defining immutable objects
Multithreading in java is a process of executing multiple threads simultaneously. The thread is basically a lightweight sub-process, the smallest unit of processing. Multiprocessing and multithreading, both are used to achieve multitasking.

Concurrency Programming in Java - 05 - Processes and Threads, Thread Objects,...Sachintha Gunasena
This session discusses about the basic building blocks of Concurrent Programming in Java, which include:
processes, threads, how to define a thread, how to start a thread, how to sleep a thread, thread interrupt, interrupt status flag, joins, simple thread example, synchronization part 1, thread interference, memory consistency errors
This ppt is related to the basics of multithreading. In this first, we will study the operating system concept link multiprogramming, multitasking, and compare it with multithreading. We will also find the difference between multithreading and multiprogramming. This slide also has diagrams to understand the concept. After that, we will study the life cycle of thread and java library for multithreading. We will also see the practical uses of multithreading. In the next slide, we will understand the practical program of multithreading. Please wait for the next ppt to understand the practical programs in multithreading in eclipse.
Provides information about Threads in Java. different ways of creating and running the thread and also provides the information about Life Cycle of the Thread
Every Java developer knows that multithreading is the root of all evil and it is quite hard to write correct code for concurrent environment. But what tasks do exist in real commercial development except running code in asynchronous way?
In this talk I will present several tasks from my real projects and solutions we designed for them. This talk is very application oriented and allows participants to extend their vision of concurrent programming.
Slide deck from my presentation on multi-threading with .NET. The presentation covers from beginner onwards and looks at current technologies (i.e. pre .NET 4.0) specifically.
What makes this extra special is the entire process of how I prepared for it, from finding content to slide deck layout to presentation prep is documented at: http://www.sadev.co.za/content/how-i-build-presentations-series-index

This presentation is about advanced multithreading and concurrency in Java. I have tried my best to explain the concepts with code. Feel free to reach me if you have any questions or concerns.
Java assigns each thread a priority that determines how that thread should be treated for the others. Thread priorities are integers that specify the relative importance of one thread to another.
A priority is meaningless as an absolute value; a higher priority thread does not run any faster than a lower-priority thread if it is the only thread running. Instead, a thread’s priority is used to decide when to switch from one running thread to next.
Java is a programming language and computing platform.
Java is composed of a number of key components that, as a whole, create the Java platform.
Two main components are :
The Java Virtual Machine.
The Java Application Programming Interface (API).
The Java platform is designed from the ground up to support concurrent programming, with basic concurrency support in the Java programming language and the Java class libraries.
2. Defining and Starting a Thread
Three ways
● Provide a Runnable object.
● Subclass Thread.
● Using Executor Interface
3. public interface Runnable
The Runnable interface should be implemented by any class whose
instances are intended to be executed by a thread. The class must
define a method of no arguments called run.
void run( )
starting the thread causes the object's run method to be called in
that separately executing thread.
6. Extending Thread class
The Thread class itself implements Runnable, though its run method
does nothing. An application can subclass Thread, providing its own
implementation of run method.
10. Runnable vs. Thread
● Runnable object, is more general, because the Runnable object can
subclass a class other than Thread.
● Sub-classing Thread is easier to use in simple applications or Testing
code , but is limited by the fact that your task class must be a
descendant of Thread
11. Thread scheduling
How each task will be run, including details of thread use, scheduling,
etc.
This code need to be seprated from the
instantiating thread class.
12. a way of decoupling task submission from the mechanics of
how each task will be run.
Task submission
The Executor will provide the mechanics of how Task will be executed.
15. The best approach is to separate the Runnable from the execution task
and it is compulsory for large-scale applications.
16. Pausing Execution with Sleep
Thread.sleep causes the current thread to suspend execution for a
specified period.
This is an efficient means of making processor time available to the other
threads of an application.
19. Two overloaded versions of sleep are provided
● sleep time = millisecond
● sleep time = nanosecond
However, these sleep times are not guaranteed to be precise, because
they are limited by the facilities provided by the underlying OS.
