I have created my website using Java Enterprise Edition (JSP/Servlets) and MySql 8 for my database. It is a typical CRUD application with a feature that let the user track the car's location.
I thought of using Flutter since it will save me time with its cross-platform capabilities but I have'nt found any documentations that will make the user login from the app to my website and fetch some data.
I'm pretty sure it is possible somehow. Otherwise is there a way to simulate my website as fast as possible without using Chrome obviously.
Read the concept of Rest APis.Simply use the api to fetch data and you can also save data through api.You need to Connect your app to your web APi.

I am developing one android application in java and i am using neo4j as a database for this app.
Lets, consider i will store the static cypher query in a string. Then after the user clicks on the button, i want to send this query(string) to neo4j server and then execute it on neo4j server and return the result.
My question is that, Is it possible? If yes, how can i do this ? Is there any easy/proper way to do?
Any help will be highly appreciated.
If you want to talk directly to Neo4j, you can use either:
The HTTP API
The Binary Bolt Protocol
If you would rather use middleware, there are many many different options:
Java
.NET
JavaScript
Python
Go
Ruby
PHP
...
When building mobile apps my personal preference is to build a standard API in a middleware server then use HTTPS calls from the app (neo4j-graphql-js has also been awesome for a couple projects), but there are enough stacks that you have the freedom to do it your way.

I have photo sharing application running on Parse. So if I will migrate to Parse Server, should I change my Android Code or it's just backend thing? And what is the best and the easiest way to migrate from parse without building new system on my own physical server.
Thank you.
If you are migrating to parse server, you shouldn't need to change your Android code. You will need to update to the latest android sdk and initialize parse with your own serverURL however. The serverURL is wherever you decide to host your parse server.
Hosting parse server is straight forward. Check out the parse server example here. They have links to one click deployment to a bunch of different paas providers such as heroku. If you have a lot of cloud code the migration process can become more complicated and is probably out of scope for this question. Most of it is outlined in the docs however.

So I'm starting an android project, very new to it and to java.
But I have a knowledge in programming, especially VB.
I'm planning to create and app for certain users to see the data from a database. Is it possible without an internet connection? If not, will be a difficult task?
Where is the database? Is it online? When you say "Data Connection" do you mean Edge/4G/LTE or WiFi or Bluetooth? Your device has to connect at least once to the database in order to copy over the required data, and it depends on the database, but you might as well just copy it locally all over to the device itself.
Here are few starting points:
Internet
WiFi
Bluetooth
Database (SQL)
I also recommend getting this book for beginners (try Google-ing it, you know...) . It was very helpful for me to use it. In about a week (if you are fast like that) you can have a pretty solid experience and understanding.

I am attempting to build a database that will allow a user to upload their music to be accessed by someone else/third party. How would I create it so that the music can be uploaded to a database but providing a path for it to be accessed from where it is stored?
As in A Band upload “Song” and it is then streamed by A Fan.
If it can't upload to a database I need to upload it to a server.
We are building the back end in Java and the front end in HTML.
We are also using Glassfish and Netbeans for writing the code.
You can store files in a BLOB field in a database for example. Another possibility would be to store them directly on the file system, but it has its problems (such as the lack of metadata).
Then you'll need to figure how you want to map each file, for example http://myserver.com/Artist/Album/Songname or http://myserver.com/listen?uniqueid=743.
File upload servlets are available all over the web, so that shouldn't be a problem. The rest is up to your programming skills (this might be too big of a project for you).
Then you'll just need to connect those things together, and that's the part where you start to program (or hit the Google hard).

I am a student. I need to make a application. I have built the GUI. Now I need to know how to do it?
I have heard about sql server compact, but does it work together with j2me? If not, something to solve the problem?
It will be better if you can pass me a example. If you couldn't, not worry, I just to need to know a database program for mobile (with j2me).
Could it be possible without use a database program? For example, using a text file? Or any other storage mechanism.
Appreciate any help.
In j2me you can use RMS. But you can't handle with large data. Some Third party database's also available for j2me development. You can use that API's. Also refer this existing discussion on same in this forum. And look at database connection using j2me article.
