1. The document discusses getting started with programming in Java, including compiling and running a simple "Hello World" Java program. It explains that a Java program is written as source code in a .java file, then compiled using the javac compiler into a .class file, which is run by the Java Virtual Machine (java).
2. It provides the code for a simple "Hello World" Java program consisting of a main method that prints the text, and explains some key aspects like class and file names.
3. It describes using the terminal to navigate directories and run the javac compiler and java programs, as well as downloading the Java Development Kit for the compiler and JVM.

Old Java lectures by my teacher Karim Zebari at Software Department College of Engineering University of Salahaddin-Erbil. The topics are:
- Multithreading
- Security in Java
- Java Beans
- Internationalization
- Java Servlets
- Java Server Pages
- Database access in Java
- More GUI Components & Printing
- Remote Method Invocation (RMI)
- Java Collections Framework
Programming is the process of taking an algorithm and encoding it into a notation, a programming language so that it can be executed by a computer. Although many programming languages and many different types of computers exist, the important first step is the need to have the solution. Without an algorithm, there can be no program.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

This content is particularly important, and will be
tested in either the coursework, class test or
exam.
🤓
This is not my area of expertise, but may still be
interesting or relevant to another module. This
will not be tested.
🤐
This is for interest only, and will not be tested in
either the coursework, class test or exam.🤔
There is content in this slide that we will revisit
at a later date.😴
4. SYMBOLS TO LOOK OUT FOR
4
Slides with no symbol are all of equal
importance, and may or may not be tested in the
coursework, class test, or the exam.
This slide features animations, which were
presented in the lecture, and may not appear
well in print.
🙈
🖥
You should be implementing all the code in these
slides in your lab sessions (line-by-line), but this
symbol tells you that this code is particularly
important, or alerts you to the presence of
particular tasks, which need to be completed.
5. To understand a definition of programming, and some open
areas of debate around the subject.
To write and run one of the simplest Java programs.
GETTING STARTED: OBJECTIVES
5
8. Formally?
• "Writing a sequence of instructions that are designed to
solve a particular problem in a formal, constructed
language."
• "Writing stuff in a made up language on your computer so
that other stuff happens on your computer."
A PROPOSED DEFINITION
8
Most people know informally.
9. This topic is often debated.
Certainly mostly scientific.
• A set language; the logical resolution of problems.
But definite artistic elements.
• Visual code style; creative solutions.
Because of the artistic element of programming, the code I show you, and, to
some extent, the topics I share with you, will always be influenced by my
style.
• Others, perhaps even those of you with programming experience, may
prefer to do things in different ways.
• The fundamentals are style-independent.
PROGRAMMING: AN ART OR A SCIENCE?
9
13. When you know the syntax (key words) and semantics (the
meaning of these words) in every programming language?
• I don’t think so.
• This is the `how’ of programming.
• This can be obtained simply through memory.
WHEN CAN YOU CALL YOURSELF `A PROGRAMMER’? (1)
13
14. When you develop a sense for how to solve problems by
breaking them down; you're able to abstract the world; and
you know which approaches to apply in different
circumstances
• I think so.
• This is the `what’ of programming; even the pros use
web searches for the `how’ element of programming,
but the `what’ of programming cannot be obtained
from Google.
• This can only be obtained by practising.
WHEN CAN YOU CALL YOURSELF `A PROGRAMMER’? (2)
14
15. This emphasises the difference between learning a programming
language (e.g. learning Java) and learning to program.
In PPA, we will focus on Java, but it is important to remember
that this is just a vehicle for teaching you how to program.
• (I’ll say it again) Practise (programming), don’t just
memorise (Java syntax).
• This will help you develop the fundamental skills
associated with being a programmer.
• A lengthy process that may stretch beyond PPA.
• Pedagogy necessitates toy examples. It may not be until
you meet real programming tasks that skills develop.
PROGRAMMING VS. WRITING USING A PROGRAMMING LANGUAGE
15
18. Most programs start their lives as simple text files, which
contain our source code.
In Java, these files have the extension .java (which you typically
alter manually from .txt after saving your text in a text editor).
START WITH A TEXT FILE
18
19. We then need to transform this simple text file (and the
source code it contains) into a program.
To do this, we need a specialist piece of software called a
compiler.
Like other software, the compiler can be downloaded from
the Internet (see KEATS).
Like most pieces of software, a compiler takes a file as input
(our text file), and produces a different type of file as output
(a program).
UNDERSTANDING THE ROLE OF THE COMPILER (1)
19
20. UNDERSTANDING THE ROLE OF THE COMPILER (2)
20
A music converter
A word processor
The Java compiler (javac)
21. The compiler produces our program, a .class file, which is
then read by the Java virtual machine, another piece of
software (which can also be downloaded, see KEATS)
designed to run Java programs and, typically, produce
output that can be viewed.
UNDERSTANDING THE ROLE OF THE JAVA VIRTUAL MACHINE (1)
21
22. UNDERSTANDING THE ROLE OF THE JAVA VIRTUAL MACHINE (2)
22
The Java virtual machine (java)
A music player
A document reader
24. When we use software such as a video converter to convert
files, or we use a word processor, we input our source files
(.mp3 file, .docx file) into the software using the GUI.
• We might right-click on the .docx file and select `open
with Microsoft Word’.
When we use software such as the Java compiler and the Java
virtual machine to compile and run programs, we input our
source files using a terminal (a command line interface).
• It is possible to run compiled (Java) programs from the
GUI, but it requires a more complex compilation
configuration.
USING THE COMPILER AND THE JAVA VIRTUAL MACHINE
24
25. THE TERMINAL (1)
25
The terminal is a text representation of a location in the file system.
You issue commands in order to move through the file system.
26. 🖥
Experiment with the terminal, and different commands, in
your laboratory session. The commands you need will vary
between operating system.
• How do you change directory?
• How do you list what is in the current directory?
• How do you find out your current location in the file
system?
THE TERMINAL (2)
26Topic1-1
27. The equivalent of right-clicking on an application and selecting
`open with’, on the terminal, is to write the name of the application
you wish to run, followed by the name of the file you wish to input.
• This assumes that the application you wish to run is installed
(i.e. exists) somewhere on your computer.
• The terminal does not necessarily know by default where the
application you may wish to run is stored.
• So, if you wish to use the Java compiler and the Java virtual
machine on your own machine you may have to tell the
terminal where to find these two applications by updating
your terminal configuration after you have downloaded and
installed both piece of software (details on KEATS).
THE TERMINAL (3)
27
28. THE TERMINAL (4)
28
The name of the Java compiler software is javac.
The name of the Java virtual machine software is just java.
Note that we omit the .class extension when we are
inputting a compiled Java program.
29. There should now be a clear process for compiling and
running a Java program.
1. Write the program in a text file.
2. Change the extension of the program to .java.
3. In a terminal, navigate to the directory containing
your .java file.
4. (Assuming the Java compiler and the Java virtual machine
are installed and available to the terminal) Run the compiler
with the .java file as input to produce a .class file.
5. Run the virtual machine with the .class file as input.
SUMMARY: FROM TEXT TO PROGRAM (1)
29
31. On KEATS you will find links to download (and then install) the Java
Development Kit, which includes the Java compiler and the Java virtual
machine.
• Programming languages, like Java, come in versions, each with
slightly different keywords and conventions. We may briefly touch
on some of the latest Java features in this course (Java 1.8), so make
sure you download the latest version. But in general we won’t teach
to a particular version.
Follow the instructions given on KEATS to configure your terminal in order
to find the javac and java software (if needed).
• Confirm that the terminal can find this software by entering both
commands into the terminal.
In our laboratories, everything is already installed for you.
REMINDER: KEATS

33. A SIMPLE JAVA PROGRAM
33
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
}
}
Must be inside a file called HelloWorld.java
34. 🙈
A SIMPLE JAVA PROGRAM: CODE BLOCKS (1)
34
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
}
}
This code has a clear structure. It is organised into nested blocks, as
indicated by the curly braces, new lines and indentation.
Must be inside a file called HelloWorld.java
35. 🙈
A SIMPLE JAVA PROGRAM: CODE BLOCKS (2)
35
public class HelloWorld { public static
void main(String[] args)
{ System.out.println("Hello World"); } }
New lines and indentation are optional, but greatly increase readability.
Must be inside a file called HelloWorld.java
36. 😴
A SIMPLE JAVA PROGRAM: THE MAIN METHOD
36
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
}
}
Must be inside a file called HelloWorld.java
37. A Java class requires something called a main method in order to be run by
the Java virtual machine.
• Any code we run has to be either in the main method or be called by it.
Because the main method contains several reasonably advanced pieces of
syntax, I am going to have to ask you to use this code as boilerplate.
• To use a piece of code without altering it (including its case), or really
understanding its operation.
• This is considered an pedagogical sin, but is unavoidable.
If this does not work for you, consider changing your learning path
• Reminder: see the `Support’ section on KEATS.
There will be several points in the course at which I will (necessarily) ask you
to accept boilerplate code, but we will always come back to it.
ASIDE: BOILERPLATE CODE
37
38. 🙈
A SIMPLE JAVA PROGRAM: CLASSES AND CLASS NAMES (1)
38
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
}
}
Some more boilerplate, for now.
Any code we write has to be
placed inside the block associated
with something called a class.
The text following the class
keyword is the name of the
class and a title that
summarises the functionality
of the code inside.
Must be inside a file called HelloWorld.java
39. Each file can only contain one public class.
The name of this class must match the name of the file in
which the class resides.
Therefore, at this stage, we will consider classes to be
roughly equivalent to files.
• One file for each class.
• Later on in the course, we’ll see that this isn’t strictly
true.
A SIMPLE JAVA PROGRAM: CLASSES AND CLASS NAMES (2)
39
40. Not all the words in a Java program have a special meaning. Some
are selected by us.
NAMING RULES AND CONVENTIONS IN JAVA (1)
40
But there are rules for human selected text (intuitive)
• Cannot begin with a number (because we wouldn’t be able to
identify values).
• Cannot contain spaces.
• Cannot contain symbols other than $ and _.
• Cannot be reserved Java keywords (such as class).
public class IsThisLectureReallyStillGoingOn {
41. camelCase notation is typical, but not enforced
• Class names capitalise the first letter (HelloWorld)
Making intelligible and presentable class name choices is part of the
artistic element of coding.
NAMING RULES AND CONVENTIONS IN JAVA (2)
41
Using the same class name twice will result in a name conflict.
• But any name selected will differ from the same name written
in a different case.
public class isTHISLEctur3reallystill_goingon {
42. All inside a file called HelloWorld.java
A SIMPLE JAVA PROGRAM: SEMI-COLONS
42
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
}
}
43. 😴
All inside a file called HelloWorld.java
A SIMPLE JAVA PROGRAM: PRINTING OUTPUT
43
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
}
}
44. TRYING IT OUT: PROGRAM OUTPUT
44
The Java virtual machine (java)
Text output from a program is printed in the terminal, after the
program has been passed to the Java virtual machine.
45. Please avoid using IDEs for the first few weeks of term (e.g.
Eclipse, Netbeans, IntelliJ etc.) or at least disable features
like code completion and code structuring.
• Using an IDE at this stage will be like learning to ride a
bike with stabilisers, and then never taking them off
(you won’t learn to ride properly).
You can start thinking about and exploring the potential
uses of version control.
A NOTE ON SOFTWARE
45
46. You actually now have all the tools you need to write and run Java programs.
How can you practise going forward?
• Attend labs, completing the lab slides and coursework tasks.
• Watch the KEATS `Challenge Forum’ for additional challenges and
problems
• Text books often contain hundreds of problems; specialist coding
challenge books exist; or search online.
• But try not to jump ahead, or approach things in different ways, unless
you find yourself struggling.
• Make something up
• If you want to write a program that changes the lights behind your
television to match the colour of the content being played, do it.
