Hello I would like to know if you can help me with this issue,

1. How can I create a web application.

2. Is it possible to view well code app and copy the code, so I can put it into app creator software by making changes.

If all those 2 questions all possible I would like to know via comment thank.

Hi Gabby,

First of all, Welcome to Coderanch, I hope you have an awesome time here I have moved your post to a more appropriate forum to get better answers.

A java web application can be deployed in a container such as jetty or tomcat. Are you aware of how servlets work ? if not, I would suggest that you first look at : https://docs.oracle.com/javaee/7/tutorial/servlets.htm
The simplest web application would consist of servlets and jsps pages.

If you want to study how to write good code, the best example would be the actual java source, you can look at the source code for the collection api and other similar apis within java. The source code is available in the jdk folder as "src.zip".

Do share your source code for your web application so that we can guide you along.

I don't know how your general knoweledge of java is, but if you're familiar enough with the basics, this might be a good place to start.
Also to state the obvious, know that most idea's let you on start of a new project choose whitch kind of program you want to create, if you choose a webapp, you start off with a mini fullworking webapp, provided you did the prerequisites, like installing a webcontainer.

I would use springboot, you can get a Web app up and running in minutes using the initializr and you don't need to install tomcat.

Writing servlets by hand is OK for learning but you wont find many (if any) companies who are doing this anymore, only legacy systems.
