Introduction to khttp khttp is a lightweight and user-friendly HTTP client library for Kotlin that simplifies making HTTP requests. It provides a more intuitive and concise syntax compared to the standard Java HTTP libraries. khttp is built on top of the Apache HttpClient library and allows you to perform various
Introduction In modern applications, making HTTP requests is a common task for accessing APIs, fetching data from web services, or interacting with remote resources. In Java, there are several libraries and APIs available to perform HTTP requests. In this article, we will explore how to do a simple HTTP request
Introduction to Regular Expressions (RegEx) Regular expressions (RegEx) are powerful tools for pattern matching and string manipulation. They allow you to define complex search patterns that can be used to match and manipulate text. In Java, the java.util.regex package provides support for working with regular expressions. However, when working with
Introduction to Sidecar and Init Container In Kubernetes, containers are the building blocks of applications deployed on the cluster. Each container within a pod performs a specific task, and often applications require additional functionality beyond their main task. Kubernetes offers two ways to augment the capabilities of a pod: Sidecar
Introduction to SNMP Traps Simple Network Management Protocol (SNMP) is a widely used protocol for monitoring and managing network devices and systems. SNMP traps are asynchronous notifications sent by managed devices (agents) to a central network management system (NMS) when specific events or conditions occur. SNMP traps allow administrators to
Introduction The loopback device, often referred to as “lo,” is a virtual network interface in a computer system that allows network communications to occur within the same machine. It is a special interface that operates entirely within the software layer and does not rely on any physical network hardware. In
Introduction Java 8 introduced the Stream API, a powerful functional programming construct that allows you to perform operations on collections in a concise and expressive manner. Kotlin, being a modern programming language with a focus on functional programming, also provides similar features for working with collections. In this article, we’ll
Introduction to Dependency Injection Dependency Injection (DI) is a design pattern used to manage the dependencies of an application by providing objects (dependencies) to a class instead of allowing the class to create them itself. This pattern promotes loose coupling between classes, making the code more maintainable and easier to
Introduction In Kotlin, the “when” expression is a powerful construct used for conditional branching. It is similar to the traditional “switch” statement in other programming languages, but with more flexibility and enhanced features. The “when” expression allows you to check an expression against multiple branches and execute the code block
Introduction When developing Java applications, it’s essential to gracefully handle shutdown events to perform cleanup tasks before the application terminates. Java provides a mechanism called “shutdown hooks,” which allow you to register threads that will be executed when the JVM (Java Virtual Machine) is about to shut down. In this
