This presentation will give a brief idea about threads.
This presentation gives you what is required if you are a starter.
This has the lifecycle, multithreading and differences between multithreadind and normal threading.
This presentation even have example programs.
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.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2. TOPIC INCLUDES:
Introduction to Thread
Creation of Thread
Life cycle of Thread
Stopping and Blocking a Thread
Using Thread Methods
Thread Priority
Thread Synchronization
DeadLock
3. INTRODUCTION TO THREAD
• Process and Thread are two basic units of Java
program execution.
• Process: A process is a self contained execution
environment and it can be seen as a program or
application.
• Thread: It can be called lightweight process
• Thread requires less resources to create and exists in the
process
• Thread shares the process resources
5. MULTITHREADING
• Multithreading in java is a process of
executing multiple processes simultaneously
• A program is divided into two or more
subprograms, which can be implemented at
the same time in parallel.
• Multiprocessing and multithreading, both are
used to achieve multitasking.
• Java Multithreading is mostly used in games,
animation etc.
7. MULTITHREADING Contd.
ADVANTAGE:
It doesn't block the user
can perform many operations together so it
saves time.
Threads are independent so it doesn't
affect other threads
8. CREATING THREAD
• Threads are implemented in the form of objects.
• The run() and start() are two inbuilt methods
which helps to thread implementation
• The run() method is the heart and soul of any
thread
– It makes up the entire body of a thread
• The run() method can be initiating with the help
of start() method.
10. CREATINGTHREAD Contd.
1. By Extending Thread class
class Multi extends Thread // Extending thread class
{
public void run() // run() method declared
{
System.out.println("thread is running...");
}
public static void main(String args[])
{
Multi t1=new Multi(); //object initiated
t1.start(); // run() method called through start()
}
}
Output: thread is running…
11. CREATING THREAD Contd.
2. By implementing Runnable interface
Define a class that implements Runnable
interface.
The Runnable interface has only one method,
run(), that is to be defined in the method with the
code to be executed by the thread.
12. CREATINGTHREAD Contd.
2. By implementing Runnable interface
class Multi3 implements Runnable // Implementing Runnable interface
{
public void run()
{
System.out.println("thread is running...");
}
public static void main(String args[])
{
Multi3 m1=new Multi3(); // object initiated for class
Thread t1 =new Thread(m1); // object initiated for thread
t1.start();
} }
Output: thread is running…
13. LIFE cycle of a thread
• During the life time of a thread, there are
many states it can enter.
• They include:
1. Newborn state
2. Runnable state
3. Running state
4. Blocked state
5. Dead state
15. LIFE cycle of a thread contd.
Newborn State:
The thread is born and is said to be in newborn
state.
The thread is not yet scheduled for running.
At this state, we can do only one of the following:
• Schedule it for running using start() method.
• Kill it using stop() method.
16. LIFE cycle of a thread contd.
Runnable State:
The thread is ready for execution
Waiting for the availability of the processor.
The thread has joined the queue
17. LIFE cycle of a thread contd.
Running State:
• Thread is executing
• The processor has given its time to the thread
for its execution.
• The thread runs until it gives up control on its
own or taken over by other threads.
18. LIFE cycle of a thread contd.
Blocked State:
• A thread is said to be blocked
• It is prevented to entering into the runnable and the
running state.
• This happens when the thread is suspended, sleeping,
or waiting in order to satisfy certain requirements.
• A blocked thread is considered "not runnable" but not
dead and therefore fully qualified to run again.
• This state is achieved when we
Invoke suspend() or sleep() or wait() methods.
19. LIFE cycle of a thread contd.
Dead State:
• Every thread has a life cycle.
• A running thread ends its life when it has completed
executing its run( ) method. It is a natural death.
• A thread can be killed in born, or in running, or even in
"not runnable" (blocked) condition.
• It is called premature death.
• This state is achieved when we invoke stop() method or
the thread completes it execution.
20. Thread methods
• Thread is a class found in java.lang package.
Method Signature Description
String getName() Retrieves the name of running thread in the current
context in String format
void start()
This method will start a new thread of execution by
calling run() method of Thread/runnable object.
void run() This method is the entry point of the thread. Execution of
thread starts from this method.
void sleep(int sleeptime)
This method suspend the thread for mentioned time
duration in argument (sleeptime in ms)
void yield()
By invoking this method the current thread pause its
execution temporarily and allow other threads to
execute.
void join()
This method used to queue up a thread in execution.
Once called on thread, current thread will wait till calling
thread completes its execution
boolean isAlive() This method will check if thread is alive or dead
21. Stopping and blocking
Stopping a thread:
• To stop a thread from running further, we may do
so by calling its stop() method.
• This causes a thread to stop immediately and
move it to its dead state.
• It forces the thread to stop abruptly before its
completion
• It causes premature death.
• To stop a thread we use the following syntax:
thread.stop();
22. Stopping and blocking
Blocking a Thread:
• A thread can also be temporarily suspended
or blocked from entering into the runnable
and subsequently running state,
1. sleep(t) // blocked for ‘t’ milliseconds
2. suspend() // blocked until resume() method is invoked
3. wait() // blocked until notify () is invoked
23. Thread priority
• Each thread is assigned a priority, which
affects the order in which it is scheduled for
running.
• Java permits us to set the priority of a thread
using the setPriority() method as follows:
ThreadName.setPriority(int Number);
24. Thread priority contd.
• The intNumber is an integer value to which the
thread's priority is set. The Thread class defines
several priority constants:
1. public static int MIN_PRIORITY = 1
2. public static int NORM_PRIORITY = 5
3. public static int MAX_PRIORITY = 10
• The default setting is NORM_PRIORITY. Most user-
level processes should use NORM_PRIORITY.
25. Java synchronization
• Generally threads use their own data and
methods provided inside their run() methods.
• But if we wish to use data and methods outside
the thread’s run() method, they may compete
for the same resources and may lead to serious
problems.
• Java enables us to overcome this problem using
a technique known as Synchronization.
For ex.: One thread may try to read a record from
a file while another is still writing to the same file.
26. Java synchronization contd.
• When the method declared as synchronized,
Java creates a "monitor" and hands it over to
the thread that calls the method first time.
synchronized (lock-object)
{
.......... // code here is synchronized
}
27. deadlock
• Deadlock describes a situation where two or
more threads are blocked forever, waiting for
each other.
• when two or more threads are waiting to gain
control on a resource.
For example, assume that the thread A must
access Method1 before it can release Method2, but
the thread B cannot release Method1 until it gets
holds of Method2.
