The document discusses various Java programming constructs including conditional statements, looping statements, methods, and parameters. It provides examples of if-else statements, switch-case statements, for, while, and do-while loops. It also explains how to define parameterized methods, pass arguments to methods, and define methods that return values.
The document discusses operators in Java, including unary, binary, arithmetic, bitwise, shift, and instanceof operators. It provides examples of how to use various operators like increment, decrement, arithmetic assignment, bitwise AND, OR, NOT, XOR, right shift, left shift, and unsigned shift. It also covers operator precedence and demonstrates how operators in an expression are evaluated based on their predetermined precedence order.
This document discusses the differences between interfaces and abstract classes in software development. It explains that interfaces define a contract that implementing classes must follow, while abstract classes can provide default functionality for subclasses. The key differences are that interfaces cannot contain method implementations, but abstract classes can, and changing an interface can break implementing classes, while extending an abstract class allows inheriting new functionality. It provides examples of when each would be preferable, such as using interfaces for unrelated classes and abstract classes for closely related subclasses that share common behavior.
The document discusses control structures in Java, including selection (if/else statements), repetition (loops like while and for), and branching (break and continue). It provides examples of if/else, switch, while, do-while, for, and break/continue statements. The key structures allow sequencing, selecting between alternatives, and repeating actions in a program.
Automated Refactoring of Legacy Java Software to Default Methods Talk at GMURaffi Khatchadourian
Java 8 default methods, which allow interfaces to contain (instance) method implementations, are useful for the skeletal implementation software design pattern. However, it is not easy to transform existing software to exploit default methods. In this talk, I discuss an efficient, fully-automated, type constraint-based refactoring approach that assists developers in taking advantage of enhanced interfaces for their legacy Java software.
The document discusses the adapter pattern, which converts the interface of one class into another interface clients expect. The adapter pattern allows classes to work together that couldn't otherwise due to incompatible interfaces. Several examples are provided to illustrate how the adapter pattern can be used to adapt one interface to another by inserting an adapter class between them.
OCA Java SE 8 Exam Chapter 4 Methods Encapsulationİbrahim Kürce
Methods allow classes to define reusable blocks of code. They can be declared with access modifiers like public or private, return types, parameters, and exceptions. Static methods can be called without an object and are used for utility functions. Constructors initialize new objects and can call other constructors through constructor chaining. Encapsulation involves making data private and accessing it through public getters and setters to control changes to an object's state. Immutable classes cannot be modified once created.
Effective Java - Chapter 2: Creating and Destroying Objectsİbrahim Kürce
Creating and Destroying Objects: This chapter concerns creating and destroying objects: when and how to create them, when and how to avoid creating them, how to ensure they are destroyed in a timely manner, and how to manage any cleanup actions that must precede their destruction.
This document discusses key concepts in Java including abstraction, encapsulation, inheritance, polymorphism, and interfaces. It defines these concepts and provides examples. Abstraction hides unnecessary details and shows essential information. Encapsulation wraps data and functions into a single unit. Inheritance allows a subclass to acquire properties of another class. Polymorphism supports method overloading and overriding. Interfaces can be used to implement inheritance between unrelated classes and specify what a class must do without defining how. The document also discusses access specifiers, modifiers, variables, literals, and static and final keywords.
The document discusses operators in Java, including unary, binary, arithmetic, bitwise, shift, and instanceof operators.

OCA Java SE 8 Exam Chapter 5 Class Designİbrahim Kürce
Inheritance is the process by which the new child subclass automatically includes any public or protected primitives, objects, or methods defined in the parent class.
We refer to any class that inherits from another class as a child class, or a descendent of that class.
We refer to the class that the child inherits from as the parent class, or an ancestor of the class.
Java is an object-oriented programming language that is architecture-neutral, portable, distributed, high-performance, interpreted, multithreaded, robust, dynamic, and secure. It uses bytecode that is translated from Java code and interpreted by the Java Virtual Machine. Java can be used for applets, networking, internationalization, security, object serialization, and database connectivity. It is platform independent because Java code is compiled into bytecode that runs consistently on any Java platform. The document then discusses control flow statements, decision-making statements, operators, object-oriented principles of encapsulation, inheritance, and polymorphism, classes and objects, methods, access specifiers, and inheritance types in Java.

The skeletal implementation pattern is a software design pattern consisting of defining an abstract class that provides a partial interface implementation. However, since Java allows only single class inheritance, if implementers decide to extend a skeletal implementation, they will not be allowed to extend any other class. Also, discovering the skeletal implementation may require a global analysis.
Java 8 enhanced interfaces alleviate these problems by allowing interfaces to contain (default) method implementations, which implementers inherit. Java classes are then free to extend a different class, and a separate abstract class is no longer needed; developers considering implementing an interface need only examine the interface itself.
In this talk, I will argue that both these benefits improve software modularity, and I will discuss our ongoing work in developing an automated refactoring tool that would assist developers in taking advantage of the enhanced interface feature for their legacy Java software.

This document summarizes a lecture on object-oriented programming and virtual functions in C++. It discusses:
1) The difference between static and dynamic binding, and how virtual functions allow for dynamic/late binding by performing function binding at runtime based on the object's type.
2) An example showing that without virtual functions, calling a function through a base class pointer results in the base class function being called rather than the derived class function.
3) How declaring a function as virtual in the base class allows the correct overridden function to be called in the derived class when called through a base class pointer, enabling polymorphism.

This chapter discusses various types of loops in Java including while, do-while, and for loops. It covers the syntax and flow of each loop type as well as examples of using loops for input validation, running totals, and sentinel values. Nested loops are also introduced. The chapter then discusses break and continue statements before introducing file input/output.
This document provides an introduction to the Java programming language. It discusses Java's evolution and history from 1991 to present. It also covers Java fundamentals including data types, operators, decision making and looping constructs, classes and objects, arrays and strings. The document is intended as an overview of the major topics and features in Java.
This document provides an introduction to decision statements in C programming. It discusses if, else if, else statements, switch statements, nested if/else, and conditional operators. Examples are given to check even/odd numbers, profit/loss calculation, and character classification. The importance of break statements in switch is explained. Operator precedence is also briefly covered.
The document introduces Kotlin programming concepts like conditionals, null safety, nullable types, and object-oriented programming principles including encapsulation, abstraction, inheritance, polymorphism, and relationships between classes. It provides examples of syntax for if/else statements, declaring nullable types, and using the safe call and Elvis operators.
This document discusses object-oriented programming concepts. It defines encapsulation, abstraction, inheritance, and polymorphism as key features of OOP. Encapsulation hides implementation details and abstraction focuses on essential object characteristics. Inheritance creates a class hierarchy for code reuse. Relationship types between classes include kind-of, is-a, part-of, and has-a. Inheritance can be single, from one superclass, or multiple, from more than one. Polymorphism means an entity takes on different meanings in different contexts.
Java 8 introduced parallel streams to allow collections to be processed in parallel using multiple threads. While parallel streams can improve performance by splitting work across CPU cores, they also introduce challenges. Parallel streams use the ForkJoinPool by default, so long-running or blocking tasks could impact other parallel operations. Side effects must also be avoided. Parallel streams may not provide benefits with a single CPU or for I/O-bound work. Developers must consider hardware resources and task dependencies to determine if parallel streams are applicable.
This document provides an overview of key Java programming concepts including casting objects, overloading methods and constructors, wrapper classes, autoboxing, and using static variables and methods. Specifically, it discusses casting objects to access subclass functionality, defining methods with the same name but different parameters, using variable arguments, invoking parent class constructors, the equals() and toString() methods of the Object class, boxing and unboxing primitive types, and declaring static class members.
Java is an object-oriented programming language and platform. The Java Runtime Environment (JRE) includes the Java Virtual Machine (JVM) and standard class libraries. The JVM runs bytecode and handles memory management, making Java platform independent. The Java Development Kit (JDK) provides tools for developing Java applications. Java code is compiled to bytecode, which is executed by the JVM. The JVM uses just-in-time compilation and garbage collection for memory management. Java supports primitive data types, variables, conditionals, loops, and other basic programming constructs.
Visual COBOL Development for Unix and JavaMicro Focus
Do you want to reinvigorate your COBOL development environment for Unix? How about bringing your COBOL business logic into the Java ecosystem?
In this session we will investigate two major features of the Visual COBOL product line. You will see how the power of the Eclipse IDE can be used to develop your COBOL applications on remote Unix machines. You will also see how Java technologies can breathe new life into your COBOL code.
C operators allow mathematical, relational, bitwise, conditional, and logical manipulations. Decision making statements like if-else statements perform operations based on conditions being true or false. Loops like for, while, and do-while loops repeat a block of code until a specified condition is met.
This document provides an introduction and overview of the Python programming language. It describes Python as a general-purpose, object-oriented programming language with features like high-level programming capabilities, an easily understandable syntax, portability, and being easy to learn. It then discusses Python's characteristics like being an interpreted language, supporting object-oriented programming, being interactive and easy to use, having straightforward syntax, being portable, extendable, and scalable. The document also outlines some common uses of Python like for creating web and desktop applications, and provides examples of using Python's interactive and script modes.
The document discusses legacy connectivity and protocols. It describes legacy integration as integrating J2EE components with legacy systems. The key approaches to legacy integration are data level integration, application interface integration, method level integration, and user interface level integration. Legacy connectivity can be achieved using Java Native Interface (JNI), J2EE Connector Architecture, and web services. JNI allows Java code to call native methods written in other languages like C/C++. The J2EE Connector Architecture standardizes connectivity through resource adapters. Web services provide a platform-independent approach through XML protocols.
The document discusses messaging and internationalization.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

"Frontline Battles with DDoS: Best practices and Lessons Learned", Igor IvaniukFwdays
At this talk we will discuss DDoS protection tools and best practices, discuss network architectures and what AWS has to offer. Also, we will look into one of the largest DDoS attacks on Ukrainian infrastructure that happened in February 2022. We'll see, what techniques helped to keep the web resources available for Ukrainians and how AWS improved DDoS protection for all customers based on Ukraine experience
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
