1. Overview In the ever-evolving landscape of Java programming, mastering reflection is a crucial skill. Reflection empowers developers to dynamically inspect and manipulate classes, interfaces, fields, and methods at runtime. With the introduction of records in Java 14, the need to efficiently retrieve record fields and their values has become increasingly important. In this comprehensive …| Examples Java Code Geeks
Handling files is a common task, and sometimes it becomes necessary to manipulate the content within these files. One such operation is removing line breaks from a file. Line breaks can be in different formats such as '\n' (Unix/Linux), '\r\n' (Windows), or '\r' (older Macintosh systems). Line breaks create new lines in text files, sometimes …| Examples Java Code Geeks
RSocket in Spring Framework 6 offers a modern network communication protocol for building responsive, resilient, and message-driven applications. It supports bidirectional, multiplexed data streams over a single connection, facilitating efficient communication between microservices or server-client architectures, with enhanced throughput and reduced latency compared to traditional HTTP-based interactions. 1. Introduction The introduction of RSocket in Spring …| Examples Java Code Geeks
Apache Kafka provides a reliable, scalable, and fault-tolerant messaging system that enables the exchange of data streams between multiple applications and microservices. Let us delve into understanding Apache Kafka and its basics. 1. Introduction Apache Kafka is a distributed streaming platform. It is designed to handle real-time, high-throughput data feeds. Kafka provides a publish-subscribe model …| Examples Java Code Geeks
Java 21 introduces unnamed classes and instance main methods, enhancing simplicity and flexibility. Unnamed classes allow for quick, on-the-fly class definitions without a formal name, streamlining test code, or one-off implementations. Instance main methods enable executing code within an instance’s context directly, facilitating more intuitive object-oriented programming practices. Let us delve into understanding Java 21 …| Examples Java Code Geeks
One common task we could encounter is converting character arrays to integer arrays. There are several ways to convert a character array containing digits (char[]) into an integer array (int[]) in Java. In this guide, we will explore different techniques to accomplish this task. 1. Using Character.getNumericValue() Java provides a built-in method Character.getNumericValue(char) that returns …| Examples Java Code Geeks
In a Spring Boot application, validating the Boolean type ensures data integrity and application reliability. By enforcing constraints on Boolean inputs, such as true/false values, potential errors, and inconsistencies are minimized, contributing to robustness and accurate functionality within the system. Let us delve into a spring boot application example to understand the different ways to …| Examples Java Code Geeks
