Maven notes (1)

Maven life cycle and plug -in configuration Maven uses a standard life cycle model, including three life cycles: Default, Clean and Site. Each life cycle contains a series of orderly stages (Phase). Phase (Phase) When executing the Maven command, for example, MVN Compile, Maven will execute all commands from Validate to Compile in order. The complete stage list can refer to the Maven document. Goal (Goal) The goal of the Maven plugin defines specific execution tasks and is bound to a specific stage. For example, MA

Reorder List: LC medium, GFG hard

Title Link: Power buckle, GeeksForgeeks Problem -solving We need to use two pointers to point to the head and tail of the linked list. method Step 1: Use the fast slow pointer method to find the midpoint of the linked list. Step 2: Divide the linked list into two parts: the first half of FIRSTHALF and the second half of the Secondhalf. Step 3: Use the reverse () function to reverse the second half of the linked list. Step 4: Last step, merge the second half of the reversal and the first half to get the final result. Complexity Time complexity: o (n) Space complexity: o (1) Code /** * DEFINITION for Sin

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

Kotlin for Java Developers (Part 1)

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". The first part of this series will cover: Data class Use air safety Under default, unsatisfactory situation Data class This theme may soon disappear, because more and more Java developers also have experience in using records. despite this

Difference Between Clojure, Kotlin and Scala

JVM language comparison: Clojure, Kotlin and Scala The JVM ecosystem has multiple powerful programming languages, each with unique features and programming paradigms. Clojure, Kotlin, and Scala are three popular choices in JVM environments. This article will focus on comparing the differences in JVM and JDK integration between these three languages. Clojure Clojure is a dynamic functional programming language inspired by Lisp. It emphasizes immutability, concurrency and simplicity. JVM: Generate bytecode that can be run on the JVM. Can call Java classes and methods, making it ideal for integrating Java libraries, but not well integrated with Java frameworks,
