- Java livereload
- introduction This article aims to explain how to speed up your development cycle, one important step is to test the code snippet and see the results immediately after saving the code. I've been doing back-end Java and front-end JavaScript development since 1999, and I'm used to using livereload to test JavaScript code, but not enough with Java. Disclaimer: I'm not a big fan of test-driven development (TDD), and the amount of testing depends on my time and mood at the time. Even if you don't write many tests, you can see how useful it can be to play around with a few snippets of code and see the results immediately. LiveTest4j utility https://github.com/hrgda

- How I am learning java
- This article will share my experience on how to use my free time to learn the Java programming language. Here are some learning points: Table of contents language learning personal projects ecosystem language learning First, let me say that Java is not my first programming language, so my learning rate may be different from yours, depending on your experience. Currently, I am learning Java by participating in the Advent of Code challenge, which helps me become familiar with Java's general syntax, package import, file reading, exception handling, data types, etc. This method allows me to gain something almost every day in the learning process. Of course, I will also do some project practice to deepen my understanding. Let's take a look at this part. personal projects Just personally

- Merge Sort Algorithm
- Learn more about the merge sort algorithm The core idea of the merge sort algorithm is the divide and conquer method, that is, "divide and conquer". It recursively divides an array into smaller subarrays until each subarray contains only one element (which is now sorted). It then merges these subarrays into a larger sorted array. It is worth noting that the sorting process occurs during the merge phase, not the split phase. Algorithm demonstration Suppose we have an array to be sorted: We divide the array into two left and right subarrays: Continue recursive splitting until each subarray has only one element: Next, merge and sort these subarrays: smaller values on the left, larger values on the right. Final sorting: Code implementation (Java) The original J

- Object Orientation in C? Implementing an interface from scratch.
- I have always been curious about computers and always thought: "Okay, I know how to use it, but how does it really work?" In the process, I often do a thought experiment: What if I implement it from scratch? It, what would I do? In this article, we will explore how interfaces work in object-oriented programming (using Java), and then implement a humble version of the interface in C. Let's look at an example Our example is simple: calculate the price of a vehicle. If it's a car, the price will be based on its top speed; if it's a motorcycle, the price will be based on its displacement. We first define the behavior of the vehicle using an interface: public class Main { public interface
