Hello Guys!
First of all, i apologise for my English, but i'm Greek ... you know....
Today i start reading about java. i'm not a programmer and i don't know if this comunity can help in this case or if is for only programmers.
I think that Books, pdf's and youtube tutorials are useless for someone who want to learn programming.
So i started with Netbeans - UI, a simple window with 2 buttons.
One button must shut down the pc.
The other button in an "about" button. I want to press it and to have a window with a message that describes my first attempt to make a simple java application.
So, i designed the window, i program the first button to shut down my pc with this code i found on the internet :
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
Runtime runtime= Runtime.getRuntime();
try {
Process proc=runtime.exec("shutdown -s -t 0");
} catch (Exception ex) {
javax.swing.JOptionPane.showMessageDialog(null, ex.getMessage());
and now i want to create the "about" pop up message for the second button.
After that, i want to install and run this app on my pc AND I CAN'T UNDERSTAND HOW CAN I DO THIS.
Can you guys help me??
(i'm sorry if i'm off topic, but i really want to learn programming and i found the codeacademy - books - youtube tutorials ecc so useless. I want to learn this language creating real things in real windows with UI and run those things on my pc. I hate the "hello World" examples.)

A B C
A B C
A B C
This is my output.....
Please can you write the code for java.....
But one condition, only one inner and outer for loop is exist..
|
|
|
|
|
Sounds like homework.
Also sounds like you don't need for loops.
Ultimately it sounds like you're going to fail class...

System.out.println("A B C");
System.out.println("A B C");
System.out.println("A B C");

Check the status of the read from the stream to see why it fails. I don't think anyone here would be able to guess.

I have an existing Spring MVC maven project. Everything in the current project is exactly what I need as a template for a new Spring project. Is there any way I can use the existing project as a template and rename it to a new project without changing anything but the name. I tried to recreate the existing project from scratch and just add the same existing components but am running into a lot of problems with the dependencies and other jar files as well as configurations.

I got it. All I did was select copy from the file menu and then it allowed me to rename it.

I need to add multiple controllers to my Spring MVC project which only has one right now. My current project only has one SpringDispatcher in the web.xml and it maps the <url-pattern>/</url-pattern> to the '/' of the controller's @RequestMapping(value = "/") controller request mapping. Because everything is in the web.xml and there are no other xml files that do any dispatcher mapping, should I not be able to just add a new <url-pattern>/</url-pattern> with a different controller pattern to the web.xml? Below are the web.xml and the one working controller.

Provide solution with code?
|
|
|
|
|
No.
We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.
We are not here to provide you with "solution with code" - that is supposed to be your job as part of your grade.
Try it yourself, you may find it is not as difficult as you think!
If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
