Hey I am new to java and wondering where to learn about JDBC, any help is appreciated. I have looked at oracles documentation but am still having difficulty with getting even a simple database to run. Thanks in advance.
At least two sites just for jdbc tutorials :)

I used the JDBC trail when I need to write an ETL program and it helped me out quite a bit. That and the Javadocs API's.
I too had the same problem and used http://www.zentus.com/sqlitejdbc/. This helped me a lot. I was wondering what you were planning on using the database for. That would help me give you a better recommendation. However for your purposes, you may be better off with serialization.

Data recovery on android
I'm interested in learning how data recovery tools are typically implemented. I've searched online and have not been able to find much information on this topic, so I'm looking for someone who can provide an overview of how these applications work. Specifically, I would like to know what techniques and algorithms are commonly used to recover lost or deleted files from storage devices. Additionally, if you could recommend any resources or references for learning more about this topic or for implementing my own data recovery application, that would be very helpful. Thank you!
I am expecting that someone give me a clear insights on how this works.

I have to create a user interface in Java, I asked in another forum for some recommendations and somebody answered me, at that moment, few people write GUI application in JAVA, its most used .NET, could somebody help me?.
Thanks

The way with java gui is to use javaFx. For that you'll need java 8 (no other lib is needed). This is easier to use as Swing or AWT before. Also its fancier by default.
Although its somehow not new to the community(2 years), there can be some pitfalls you will run into. By now i don't see a better solution. If you need more native "look and feel" you can use the platform dependent swt which is somehow old, proofed but harder to use.

I am relatively new to programming and in need of help.
I am trying to design/develop small desktop app for a family hotel.
Do I need a database to write/read from or there is another solution to this problem.
There aren't massive amounts of information to be stored ,because of the nature of the application.
What would be a good way to approach the problem ?
Any help will be appreciated!
Sqlite is the go to solution for simple usage
You can read/write your data to files. The files can be simple text, JSON or XML. There are many Java libraries that can interact with files on disc.
Depending on your requirements you can also have an in-memory database - for example HSQL or SQLite

This may sound really silly but there is a whole documentation of the libraries and classes in java and I am trying to learn how to use this to write programs since I don't want to refer to someone else code but I was completlely lost when I look at the documentation online: http://docs.oracle.com/javase/7/docs/api/
Can someone please help me understand how i can use this?
I think you need to go up one level and look at tutorials first: http://docs.oracle.com/javase/tutorial/. Once you understand the basics of Java, then you can use the API reference to find the classes and methods you need.

I'm new to programming, and I started by learning python. However, now I'm watching a lecture series online by Stanford, and they use Java.
I'm having a hard time transitioning from Python to Java. Can someone please explain how classes work in Java in contrast to functions in Python? Public vs. Private seems strange. I've also heard 'methods' and been told they are similar to functions. Links to videos or other explanations are welcomed.
I realize this question does not have any code; but we all have to start somewhere. Thanks
You may find it better to take a step back and learn the basics of Object Oriented Programming, not necessarily related to Java specifically.
Some places to get you started:
http://docs.oracle.com/javase/tutorial/java/concepts/
http://www.codeproject.com/Articles/22769/Introduction-to-Object-Oriented-Programming-Concep
http://www.youtube.com/watch?v=c5kfCH50wl0
This is just a few, though you will find many more learning material around the web.
