Is it possible or not, knowing JAVA, HTML, PHP, to write a full-fledged WEB application?

Question

PHP

Good day. I recently started learning Java. On the agenda, there was a question. Is it possible, having at hand knowledge in Java, css, html, JavaScript, to write a full-fledged web project.
An example project would be one of the many browser games (Fight Club, Apeha, etc.).
Interested in practical implementation if it is of course possible. Or are similar projects somehow tied to PHP?
Those. I have an idea of ​​how applications are built on PHP> MYSQL, I'm interested in the possibilities and differences of JAVA in WEB development (Complexity, relatively large projects).
What will you have to face at the writing stage, at the launch stage.
Also, if such projects are possible, then what is the difference in the speed of data processing between the client-server.
Interested in the implementation of this code <?php echo "Hello"; ?> relative to JAVA, i.e. if you run this code on a web server, it will easily be displayed in the browser, but how does it happen in a JAVA environment or what is used for this.
And of course, again, if the implementation of such a project is possible in JAVA, then how will this affect the load on the client browser.

Answer 1

tomcat server jsp

Answer 2

Of course you can; it will be no worse than in PHP
"knowing JAVA, HTML, PHP" - in the title did you mean JavaScript instead of PHP?
No way. The server part does not affect the load of the browser

Answer 3

Of course you can. In fact, that's what they do. Only here the question should be asked more specifically or divided into several. The main difficulty in any web project is basically building a good architecture (Java is abstractions over abstractions, yes, yes!). If you need browser games, then there are some cool things written in Java, like this - http://netty.io, which make everything very easy...
