    Detailed explanation of Java Set: The collection of the unique element efficiently This article will explore the SET interfaces and its main implementation classes in Java to help you understand how to efficiently handle a collection that does not include duplicate elements. Source: https://www.devmedia.com.br/java-Collections-Como-Utilizar-Collections/18450 1. Java Set interface introduction The SET interface is a set that does not allow duplicate elements. It is based on a collection of mathematical operations (collections, intersections, and differences), which is very suitable for the need to ensure the uniqueness of the element. Main features: Repeated elements are not allowed. Can store

  • The difference between arrays as Lists in Java?
    The difference between arrays as Lists in Java?
    Arrays and lists are part of data structures that are crucial to software development. They are commonly used data structures. This article will dive into their differences, the evolution of arrays into lists, and their practical use cases. Good morning ?☕️, code gurus. Let's get started. What is an array An array is a data structure in computer programming used to store a series of identical data items in contiguous memory locations. Arrays are of fixed size and store elements of the same data type. They use indexes to provide fast access to elements. For example: int[] arr = {1, 2, 3, 4, 5}; System.out.println(arr[0]); // Output: 1 The evolution of arrays into lists

    Why double Loses Precision and How to Avoid It in Java
    When using floating -point numbers in Java, you may notice that Double sometimes produces accidents or inaccurate results. This behavior may cause errors, especially in financial applications or high -precision scenarios. In this article, we will explore the fundamental reasons in depth, explain how to avoid it, provide a feasible example, and discuss whether the updated Java version provides a better alternative. Why does DOUBLE lose accuracy? 1. IEEE 754 floating point number standard Double data types in Java follow the IEEE 754 floating -point number calculation standard. It uses the following method to represent the number in a binary format: 1 bit for symbols, 11 digits for index, 52 -bit use

    Java occupies a dominant position in the programming language, so I have seen that Java developers have made the same mistake when using Kotlin. Don't get me wrong. This is not to say that these are bugs, but when developers are accustomed to developing in Java, tend to produce "code odors" in Kotlin, and do not use Kotlin's function. This article will let you understand the code odor I often see and how to achieve them ideal in the "Kotlin method".
