Hello folks,

I made a very basic game named 2dBallAnimation, it's using basic vector math in order to make the Animation happen.

there is only 3 classes in the entire app:

• MainActivity.java : it gets executed when the app start
• DefaultScreenView.java : it's responsible to make the animation work by doing vector math
• V2.java : contains the x,y values of a vector and methods for vector addition, subtraction, multiplication, normalization etc..

are you Android dev or Java dev? share your thoughts about the app? feel free to give me some suggestion too.

So far I have worked on many different projects, seeing many different approaches to modern web application development including among others:

Thymeleaf, Freemarker, ZK, Angular2, Vue.js, React and Vaadin

to facilitate rendering of a UI. Obviously, there are always advantages and disadvantages and different paradigms involved.

With all the advantages that do exist with modern js frameworks, it also almost always feels like a lot of bloat and overhead to me to work with these frameworks.

More recently, I did work with Vaadin, and as a Java developer at heart, I rarely felt that much „at home“ for creating a UI.

I have to admit, it is still quite handy to know your js and css for special behaviours and edge cases, but something in me just loves working with Vaadin.

So now we can talk a lot about Performance and stuff, but Vaadin‘s simplistic approach is imho very much appealing to people who Like Java.

It might not be the best fit for everything, but it can surely get you far,

Java equips developers with convenient tools for serializing objects. Although they seem primitive at first glance, their internal implementation contains a wealth of interesting insights. In this article, we'll explore the essentials of serialization and its nuances. Let's see how it operates under the hood!

If there was one reason I liked coding in Java, it'd be AssertJ and its brilliant extensibility.

The ability to create custom assertions makes the test code concise and read naturally.

So I am working on a homework project for my network architure class were I have to devlop an FTP program using UDP (not TCP). I was able to get my GET and PUT functions to send a 21byte test file and it worked. However when I tried to do a 1MB file the program hanged and did not send all of the data. I need to be able to send files of 1MB, 25MB, 50MB, and 100MB. Here is my code.

GET (Client Side)

 undefined

    
 private static void getFile(String serverFilePath, String clientFilePath) throws IOException 
    {
        clientFilePath = clientFilePath.replaceAll("^\"|\"$", ""); //Strip quotes if any.
        if(!clientFilePath.startsWith("/"))
            clientFilePath = currentDir + "/" + clientFilePath;
        
        sendMessage("GET " + serverFilePath);
        
        //Write file to client
        try (FileOutputStream fos = new FileOutputStream(clientFilePath)) 
        {
            while (true) 
            {
                byte[] buffer = new byte[BUFFER_SIZE];
                DatagramPacket packet = new DatagramPacket(buffer, buffer.l
