Packages and interfacesvanithaRamasamy

This document discusses object oriented programming concepts in Java including packages, interfaces, and how they relate. It provides details on how to define and use packages to organize classes. Interfaces are introduced as a way to specify common behaviors without defining how they are implemented. The key points covered are how to define interfaces, implement interfaces in classes, access implementations through interface references, allow for partial implementations, and extend interfaces.

Datatypes in pythoneShikshak

The document discusses various Python datatypes. It explains that Python supports built-in and user-defined datatypes. The main built-in datatypes are None, numeric, sequence, set and mapping types. Numeric types include int, float and complex. Common sequence types are str, bytes, list, tuple and range. Sets can be created using set and frozenset datatypes. Mapping types represent a group of key-value pairs like dictionaries.

Operator OverloadingNilesh Dalvi

Operator overloading allows user-defined types in C++ to behave similarly to built-in types when operators are used on them. It allows operators to have special meanings depending on the context. Some key points made in the document include: - Operator overloading enhances the extensibility of C++ by allowing user-defined types to work with operators like addition, subtraction, etc. - Common operators that can be overloaded include arithmetic operators, increment/decrement, input/output, function call, and subscript operators. - To overload an operator, a member or friend function is declared with the same name as the operator being overloaded. This function performs the desired operation on the class type. -

- Arrays allow storing multiple values in a single variable. They are useful for problems that require working with several variables at once, like calculating exam averages for 100 students. - Arrays are initialized with a size and values can be stored and retrieved using indexes. Common issues include accessing indexes outside the array bounds or failing to initialize arrays properly. - Command line arguments provide a way to pass user input to a program via the command line when it is launched. The arguments are stored in a String array that is initialized for the program.

Constructor pptVinod Kumar

Constructor is a special method in Java that is used to initialize objects. It has the same name as the class and is invoked automatically when an object is created. Constructors can be used to set default values for objects. A class can have multiple constructors as long as they have different parameters. Constructors are used to provide different initial values to objects and cannot return values.

Branching statementsArunMK17

BRANCHING STATEMENTS if statement if – else statement if – else if ladder Nested if Goto Switch case programs output flowchart Branching / Decision Making Statements The statements in the program that helps to transfer the control from one part to other parts of the program. Facilitates program in determining the flow of control Involves decision making conditions See whether the condition is satisfied or not If statement; Execute a set of command line or one command line when the logical condition is true. It has only one option syntax with flowchart If else if ladder; Number of logical statements are checked for executing various statement If the first condition is true the compiler executes the block followed by first if condition. If false it skips the block and checks for the next logical condition followed by else if. Process is continued until a true condition is occurred or an else condition is satisfied. Switch case; Multiway branch statement It only requires one argument of any type, which is checked with number of cases. If the value matches with the case constant, that particular case constant is executed. If not the default statement is executed. Break statement – used to exit from current case structure Nested if else; When a series of decisions are involved we use more than one if-else statement. If condition is true control passes to first block i.e., if block. In this case there may be one more if block. If condition is false control passes to else block. There we may have one more if block.

Leveraging Foundation Models to Infer IntentsKeheliya Gallaba

Invited Talk at RAISE 2025: Requirements engineering for AI-powered SoftwarE Workshop co-located with ICSE, the IEEE/ACM International Conference on Software Engineering. Abstract: Foundation Models (FMs) have shown remarkable capabilities in various natural language tasks. However, their ability to accurately capture stakeholder requirements remains a significant challenge for using FMs for software development. This paper introduces a novel approach that leverages an FM-powered multi-agent system called AlignMind to address this issue. By having a cognitive architecture that enhances FMs with Theory-of-Mind capabilities, our approach considers the mental states and perspectives of software makers. This allows our solution to iteratively clarify the beliefs, desires, and intentions of stakeholders, translating these into a set of refined requirements and a corresponding actionable natural language workflow in the often-overlooked requirements refinement phase of software engineering, which is crucial after initial elicitation. Through a multifaceted evaluation covering 150 diverse use cases, we demonstrate that our approach can accurately capture the intents and requirements of stakeholders, articulating them as both specifications and a step-by-step plan of action. Our findings suggest that the potential for significant improvements in the software development process justifies these investments. Our work lays the groundwork for future innovation in building intent-first development environments, where software makers can seamlessly collaborate with AIs to create software that truly meets their needs.

Integrating Survey123 and R&H Data Using FMESafe Software

West Virginia Department of Transportation (WVDOT) actively engages in several field data collection initiatives using Collector and Survey 123. A critical component for effective asset management and enhanced analytical capabilities is the integration of Geographic Information System (GIS) data with Linear Referencing System (LRS) data. Currently, RouteID and Measures are not captured in Survey 123. However, we can bridge this gap through FME Flow automation. When a survey is submitted through Survey 123 for ArcGIS Portal (10.8.1), it triggers FME Flow automation. This process uses a customized workbench that interacts with a modified version of Esri's Geometry to Measure API. The result is a JSON response that includes RouteID and Measures, which are then applied to the feature service record.
