Today we learnt about the wonders of networking in Java! It was so exciting to find out how we actually receive and send information between users and servers! I adore learning about the ins and outs of CS!Networking?think of it as a web that connect one computer to anotherIt is where two or more computers are connected via a cable (could be a literal or not) to form a network. The network is co..

There are two types of interfaces to use when using Java: CLI and GUI.CLI (Command Line Interface) : this is where we use the cmd panel to execute code. Simple and lightweight but visually minimal and could be limiting.GUI: (Graphic User Interface): Heavier than CLI but visually easier for users to navigate and useToday we focused on GUI!!three main outlets for GUI:AWT: Follow the Operating syst..

Today we started the basics on threads.Honestly the lecture was a little hard to follow so I did some of my own reseach (Geeksforgeeks and chatgpt) to cover some holes in my understanding.I also looked into the Java book hat added a bit more context to the example codes we were using today.Today's notes are a combination of all three :3Usually when processing a code we tend to use a single threa..

Creating a web page using ListsToday we decided to use the List interface we learnt while studying about Collections and incorporate it into pulling data from a database and creating a functioning web page. One of the problems we ran into last time was that the user id and password that was needed was unprotected.So this time we: stored the sensitive info in a seperate class so it can store the ..

Importing data into JSP using mariaDB and try/catch Utilising what we learnt yesterday, we encorporated the try/catch method to import data onto an index.jsp page we have created and launched via Apache Tomcat. Use the setting below to set up a dynamic web project after downloading Apache tomcat. PROTIP: make sure to name the main jsp file as index as that will be the name Java will be searching..

Today we touched briefly upon the concept of interfaces and exceptions. Here is what we have learnt so far. InterfaceA special function that is hard to find in other languages except for Java. An interface is a completely abstract class that is used to group related methods with empty bodies.It can only contain abstract methods and constants (think static final).interface AAA{ public static fina..

Before we started today's lesson we did a short excercise based on what we have learn so far in class.We created a small program using different classes that prints out the interaction between an apple buyer and seller. Here is the AppleSeller class:package apple;public class AppleSeller {final static int APPLE_PRICE = 1000; // we used final static to turn the price of the apples into a constant..

Today we delved a little bit deeper into methods and different access modifiers and its functions! There are many keywords we can add infront of a member to define what exactly we want it to do! Here's a handy diagram of what settings there are! access modifiers / static , non-static/ return-type / method name(parameter... (optional)){command;command;} end of method bodyStatic As we touched upon..

Welcome back to OOP!Today we delved deeper into OOP and learn some interesting things on how they work!!Classesthere are two ways to form classes! creating it in the same file that you will be running your code increating a seperate java file!The difference is whether or not you'll be using public! it is a keyword that declares that member's access as public! this means it is visible to all othe..

Today we learnt the concept of deep and shallow copyingThese methods applies to Arrays, primitive and reference types and effect them a little bit differently! First lets define what deep and shallow copies are and the pros and cons of using them :3 Shallow Copyin a nutshell, instead of copying the content of a variable, we just copy the address of which it is stored!! so if we type:int[ ] arr01..
