Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
Keep the subject line brief, but descriptive. eg "File Serialization problem"
Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode HTML tags when pasting" checkbox before pasting anything inside the PRE block, and make sure "Ignore HTML tags in this message" check box is unchecked.
Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
Please do not post links to your question in one forum from another, unrelated forum (such as the lounge). It will be deleted.
Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
No advertising or soliciting.
We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
When answering a question please:
Read the question carefully
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar
If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome
If the question is inappropriate then click the 'vote to remove message' button
Insults, slap-downs and sarcasm aren't welcome. Let's work to help developers, not make them feel stupid.
The Window Builder Editor (if the regular install won't do it)
As best I can tell, those six tools will cover everything I'll need to go through this course.
CURRENT FAILURE: When I go to the URL which the instructor provides for placing JDK 9 on my machine, I arrive at a screen which has no link nor any observed instructions/directions/procedure/whatever for installing that version on my machine.
That seems like a lot of overkill just to learn Java; JDK 8 and Notepad is all you really need. Android studio is only required for building Android apps, and you need a solid grounding in Java before attempting it. Take a look at The Java™ Tutorials[^] where you can learn all you need.
I want to send my html form data to the server(using servlet) using Json And retrieve the data from server and represent it in graph.
How can i do that,Please help me Am a fresher and i dont have any idea about server communication ,its urgent as i have to complete my project.
I am a beginner in programming java jee, I am currently working on an application and I hangs the derapt how to establish a connection between eclipse and mysql 2014, I also ask if you have links and even book that explains how program with jee (jsf and primefaces also spring for security),
See The Java™ Tutorials[^]. Also, you do not want a connection between eclipse and mysql, but between your Java application and MySql. See the section in the tutorials on Data Bases. You can also find lots of useful information from Google.
The call to add generates the following compiler error:
error: no suitable method found for add(Radial)
parts2.add( t1 );
Since t1 is of type Radial, it is of type Tire therefore I expected it to work. I tired putting in a cast of t1 but that did not work either.
Lastly, it is much simpler to work with ArrayList<T> in Java as compared to working with List<T> in Java. ArrayList<T> would be much better alternative to your types in the code above. ArrayList<T> contains List<T> in the inheritance chain. See the documentation for more on that. ArrayList (Java Platform SE 8 )
The sh*t I complain about
It's like there ain't a cloud in the sky and it's raining out - Eminem

You cannot add a Radial object to a List of Tires, only a Tire object. If you were allowed to then you could start trying to call Radial methods, or access Radial properties on Tire objects, which is not possible.
Anyway, error trap for this statement. That would throw an error if the file didn't exist
I played with the TRY function, but it didn't detect an error.
