Introduction to Java Programming, Basic Structure, variables Data type, input...Mr. Akaash
This is First Lecture of java Programming which cover all basic points (ie. History and feature of java, Introduction to java, about variables data type and compilation....
Here I discuss about Java programming language and easiest way to solve programming problem. Java basic syntax and their uses are described briefly so that anyone can easily understand within very short time. If anyone follow the slide with proper way,I assure that he or she will find java programming interesting.
At first glance, Java byte code can appear to be some low level magic that is both hard to understand and effectively irrelevant to application developers. However, neither is true. With only little practice, Java byte code becomes easy to read and can give true insights into the functioning of a Java program. In this talk, we will cast light on compiled Java code and its interplay with the Java virtual machine. In the process, we will look into the evolution of byte code over the recent major releases with features such as dynamic method invocation which is the basis to Java 8 lambda expressions. Finally, we will learn about tools for the run time generation of Java classes and how these tools are used to build modern frameworks and libraries. Among those tools, I present Byte Buddy, an open source tool of my own efforts and an attempt to considerably simplify run time code generation in Java.

ARCHITECTING LARGE ENTERPRISE JAVA PROJECTS - vJUGMarkus Eisele
Slides for my vJUG session:
http://www.meetup.com/virtualJUG/events/221218531/
In the past I've been building component oriented applications with what I had at hand. Mostly driven by the features available in the Java EE standard to be "portable" and easy to use. Looking back this has been a perfect fit for many customers and applications. With an increasing demand for highly integrated applications which use already available services and processes from all over the place (departmental, central or even cloud services) this approach starts to feel more and more outdated. And this feel does not come from a technology perspective but from all the requirements around it. Having this in mind this post is the starting point of a series of how-to's and short tutorials which aim to showcase some more diverse ways of building (Java EE) applications that fit better into today's requirements and landscapes.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

4. JAVA
• Java programming language was originally developed by Sun
Microsystems.
• Object Oriented : In Java, everything is an Object based.
• Platform independent.
5. Virtual Machine
• A virtual machine (VM) is a software implementation of a
machine (for example, a computer) that executes programs
like a physical machine.
• Virtual machines are separated into two major
classifications:
system virtual machine and process virtual machine.
6. JVM
• A Java virtual machine (JVM) is a process virtual
machine that can execute java byte code.
• JVM converts Java byte code into machine language and
executes it.
• JVM is platform dependent : JVMs are available for many
hardware and software platforms.
• JVM gives Java the flexibility of platform independence.
7. Diagram of JVM
Java source code Byte codeJava compiler
Java Virtual Machine
Java Interpreter
Computer Operating System
Byte code loaded into JVM
9. Class loader
• All Java virtual machines include one class loader that is
embedded in the virtual machine.
• Class loader loads java classes into java virtual machine.
• Class loader reads bytecode and creates the instance of
java.lang.class.
10. Execution engine
• The execution engine helps JVM to convert bytecode into
machine code.
• A mechanism responsible for executing the instructions
contained in the methods of loaded classes.
11. Stack
• Stack stores various method arguments and local variables of
any method .
• There are three registers that help in stack manipulation.
– Vars register
– Frame register
– Optop register
12. Sections in stack
• Local variable
– This section contain all local variable being used by current method.
• Execution environment
– Execution section is used to maintain the operation of stack itself.
• Operand stack
– The operand stack is used as a work space by bytecode instruction.
13. Method Area
• This is the area where byte code is placed.
• The program counter points to the next instruction in the
method area.
• After the execution of an instruction , JVM set pc to next
instruction.
14. Garbage Collected Heap
• The object in java program are stored in Garbage collected
heap.
• Arrays in java program are objects, hence they also stored
in heap.
• Java does not have a free operator to free any previously
allocated memory.
• Java done this automatically by Garbage collection
mechanism.
15. • JRE is an acronym for Java Runtime Environment.
• Java Runtime Environment contains JVM, class libraries, and
other supporting files.
• It does not contain any development tools such as compiler,
debugger, etc
JRE
16. JDK
• JDK is an acronym for Java Development Kit . It physically
exists . It contains JRE + development tools.
17. JIT
• Just-in-time Compiler -is the part of the Java Virtual Machine
(JVM) that is used to speed up the execution time.
• JIT compiles parts of the byte code that have similar
functionality at the same time, and hence reduces the amount
of time needed for compilation.
18. Is java a compiled or interpreted
language ?
• Java is a compiled language because the source code is
converted into byte code.
• Java is an interpreted language because the byte code is
interpreted by a virtual machine.
