I want to create a program that i can use to save articles to read at a later date. I’ve made the basic CRUD features but i want to add users and make sure the users can only see the articles that they have saved.

I have coded in Java before, but not any serious production-ready code. I took a course or two on Java and that was it. Back then, I used Intellij's IDEA as my Java IDE on a windows machine. Nowadays, I am trying to build web apps with spring boot using neovim as my editor on a linux machine. I've been tryin to make the transition from hand-held coding with IDEA into more manual stuff that allows me to directly interact with my tools. For one, I've been trying to learn Gradle recently, and while I mostly get what it does and how to use it in general, I still feel like I am unable to do any ac ..read more

I am learning about OOP right now , but im a little confused as to what a constructor actually does? Fore example if we have a Person class: public class Person { private String name; private int age; private int weight; private int height; public Person(String name) { this.name = name; this.age = 0; this.weight = 0; this.height = 0; } I understand that in the constructor we are passing values in. So the instance variable is being set equal to the local variable. But why is the parameter only (String name) ? we could use a constructor that has no parameters: public Person() or we could hav ..read more

Hello all. Brand new to coding, I am in my last week of a Data Structures course and while I can digest the vast majority of it conceptually, I struggle when it comes time to synthesize it all and actually write the code for a (relatively) complex homework assignment. Any advice or recommended supplemental learning to help me get more familiar with writing and implementing various methods for things like trees and heaps, linked lists, array lists and such? Also recursion gave me a few gray hairs. submitted by /u/AlwaysFromtheFuture [visit reddit] [comments ..read more

Tried to install an older version of Java Spring, but I can't with the initializr online, so I was wondering if there were any breaking change, especially in the login and JWT auth part.
