I want to learn java by myself but I don't know the programming language. I am new to programming but I like to do.
So could you please guide me for learning Java
What software require to install it?
please attach the learning web site link for basics.
please also attach the sample examples links.
Thank You
I would recommend looking at Thinking in Java. It gives you an overview of OO as well which is essential for programming well in Java. I would also look at the tutorials from Oracle.
As to what you might need to actually write java, I'd start with a text editor and manually compile and deploy applications. This gives you a good understanding of it. After that I'd look for an IDE such as Eclipse.

I was at a conference and there were one presenter who showed some Java 8 code examples in an application, and I'm looking for the name of that or a similar app.
The application compiled all code examples and showed output but the main thing was that he didnt have to write complete java code. It automatically handled imports and class definitions. He could just focus on code he wanted to show. This made it easy to quickly create examples.
Edit; A clarification, this was not a complete IDE. It appeared to be a program specifically designed for quickly writing and testing short code examples. For example, he wrote and showed a for-each loop in Java 8, without any imports or having to create a main class or any of that syntactic fluff.
Check those Integrated Development Environments:
Eclipse
IntelliJ Idea
NetBeans
To improve your presentation you can create templates which will create necessary code for you.
I found out the contact details of the presenter and asked about the program. It turns out he was using Mac with TextMate.
Eclipse provides a similiar feature with its java scrapbook pages.
You can just enter java statements and they can be run.

I am about to start new Android app considering that Java development is not my strongest side I'd like some advice on where to start. The question is not that much about Android API it's more about the right tools and code organisation.
Should I use template app like Android Bootstrap and are there any other better than that.
How should I organize my code so it makes sense while the app grow.
Any other libraries that might help?
The app would be for downloading music and it'd be free one. There would be a server API that will deliver the content.
In my opinion you should start with a blank project and try to learn Java and understand how the classes in Android work. Using a template is not the best way to learn programming because you can easily get confused and not understand what the code does.
You implement the classic 3-Tier architecture with packages for the Domain, Repository, Controller and User Interface. This way you can stay organized and easily improve on your app.
Read Android forums, documentation and see what libraries do you need to use.
Firstly get stronger on Java development, go through the Java SE tutorial. Then you can take a look at the Android Development Getting Started page.
I'd also recommend you to invest on some good programming book

I am wondering is there something like a little guide or tutorial for a programmer who has experience in delphi and wants to learn java? Like a syntax guide etc
I've been using delphi since I was about 13 years old as it was taught in high school. I am now 19. I have become very fond of delphi and how simple it is :)
Also if anyone has any good links for netbeans tutorials for beginners I would appreciate them as well :)
You can just google "java delphi comparison" and it will turn up a lot of helpful pages. I couldn't find the document I remember from seven or eight years ago, but here are a few directly on topic:

I am working with Java at my current day job. When I learned programming, I learned C++, but haven't touched it (or had to) since 2002. I don't even remember how to do the simplest of things.
Lately, my work has been expressing a need for a C++ application built for windows.
I am looking for books/articles/blog-posts (resources) that:
teach the basics of C++?
for n00bz?
for someone who's already been programming?
teach the differences between C++ and Java?
teach the basics of the Visual .* platform?
teach the specificities of building with Visual Studio?
Why ask the question?
This question was brought on by the fact that my first program is 5 lines of C++ (sourced from documentation with a dependency on a DLL.) It's quite intimidating to figure out how to build it in the way I'd like to.
That being said, there are many elements in the snippet that I don't understand.
I definitely see that the original need is small, but I'd like to get some background on the platform/subject before I embark on even some simpler development (like the snippet) in the future.
Thanks in advance.

hi can anyone recommend a simple java web crawler that crawls a websites and return a list of links in the website ? No, i do not need a parser. Thanks for your attention.
A web crawler is (almost by definition) never 'simple'.
Two names spring to mind however (although both have a learning curve):
Nutch
Heritrix
Both are open source and can accomplish what you want, although simply listing the links in a website is not what either is built for (Nutch is designed to build a search index and Heritrix is designed to archive websites). You will need to do some custom configurations to accomplish your task.
HTTrack is a much simpler tool, but is not implemented in Java.
