I just installed netbeans 12.0 again (I formatted my computer previously), I was customizing it but now every time I make a code I have to click on the Clean And Build Project button before clicking on the Run button, which is quite a lot. tired and takes time, when that should be automatic.
For example: I create a System.out.println ("Hello"); , I run the program and nothing appears on the console, I click the Clean And Build button and now it appear on the console; I change the message from "Hello" to "How are you?", I run the program and the "Hello" that I had written previously appears, that is, the application continues executing the previous code until I click Clean And Build. How can i solve this? Greetings.
Follow the below steps.
Note:Make sure your project haven't any errors.
Go to the project Explorer.
Right click on your project.
Select Clean (Now your code will clean).
After the clean build your project.
Then you can run your project.It should be ok

I have been using Code Runner extension to build and run c++, python, and java files in Visual Studio Code. But it doesn't actually compile the program every time I run it. It just Run the program. So, If I make any change, The output in the terminal doesn't get updated and doesn't show the changes I have made. The Code Runner just build the program once and that's it. What should I do to make "Code Runner" Build or Compile the program every time I run a program using "Run" or Ctrl+Alt+N?
Got it. Here is what I did to solve the problem.
Go to Extension Settings of Code Runner Find and Mark Save File Before Run.

I think I know what you are talking about, Go to the top menu and find performance, inside look for an option something like code runner run in the terminal, check that box and then you can give input to the program.
I'm brand new to learning Python and am using Eclipse to go through a Python course. When I first started doing exercises in Eclipse, every time I opened a file from the course examples, the first time I ran it I would click the green "run" button, and it would ask me how I wanted to launch the file (as Python Run or Python Unit Test). Somewhere along the way it stopped doing that and now if I open a file that has never been run before, when I click the green run button, it just runs a different file. I can click through the drop down menus to run as and select python module and then the run button works fine any time I use that file, but I can't figure out why it won't just run new files the way that it did when I first installed eclipse.
You probably have configured to run the last file... (PyDev asks if you want to do that in a dialog and does that for you if you confirm). Still, don't worry, this is probably for the best anyways as you can just hit F9 to run your file directly without clicking anything (and Ctrl+F11 or clicking the run should now re-run the last launch you did).
Make sure you take some minutes to read http://www.pydev.org/manual_101_run.html for tips on the best way to run Python modules from PyDev.
I don't remember the name of this feature on Eclipse but it is something like that:
start 'Debug build'
Change code
reapply changes (still running that same debug build)
Now you can see the change in 'real time' without having to close the application and having to 'go' to the point you wanted
How can I do this in Intellij IDEA (and if it is possible to do using LibGDX applications)
The feature is called "hot swap". IntelliJ offers you to reload your changed classes every time you compile your application while it's running under a debugger. You can also trigger this explicitly using the Run | Reload Changed Classes menu item.
The shortcut key is F11 to start debugging. But issue is that I have to be on that file and then hit F11 to start debugging.
Eg.
my file to launch the application is "launch.py" and "example.py".
example.py is open in the editor whereas launch.py is not.
Now, if I hit F11 it will try to launch the application using "example.py" and terminates due to error (as expected).
So then I have to open the "launch.py" in the editor and then hit F11 to start debugging the application.
Is there any neater way to configure the debugging, so that it starts the application in single hit/key?
Edit: example.py is some other file (some module). It does not launch the application.
As this PyDev Eclipse Tutorial suggests:
After the first run, if you type Ctrl+F11, the last file ran is re-run. Or, if you type just F11, a debug session is started with your last run. Let's test this...
Note: This behavior changed in Eclipse 3.3 -- but it's generally recommended to restore it in the preferences at: window > preferences > Run/Debug > Launching and set the Launch Operation to Always launch the previously launched application.
This tutorial will always consider this as the default option.
So, did you have this option selected?
If you have launch at least once launch.py, then you can re-launch it easily.
Although this isn't strictly an answer to what was asked initially, it might help someone looking here that had the same problem as me...
I'm a Java developer mainly, so have the Java view open almost all the time. However, sometimes I want to run some python file to test something (or just create a quick python script, and run it)...
In the Java editor, if the current class has a main(String[] args) method, I run it with (and popup the dialog to ask me what exactly I'd like to run in the middle)
alt+shift+x, j
Unfortunately, that doesn't work in the Python view, and I've not found a similar solution - it just asks me if I'd like to run it as a Java app... however, as the VonC says, you can run the last run thing (provided you've set the preferences accordingly) with
ctrl+f11
and this seems work well with python run configurations too.
But... What if the last thing I ran was a Java program, but I now want to run the active .py file? Previously, to run the .py file, I'd have to go digging through the buttons on the toolbar with the mouse, and I tend to prefer keyboard shortcuts...
Solution! So, finally I come to the actual useful bit of this answer - I just discovered by accident (typing Ivan's suggested shortcut, but missing!), it appears that
f9
will run the currently active python file.
Hope that helps someone get just that little bit faster...
I use CTRL+SHIFT+F9 to relaunch the previous debug configuration in Pydev.
In Eclipse®, on the Run menu, click Debug Configurations or Run Configurations.
Expand the BlackBerry Simulator item.
Perform one of the following tasks:
To work with an existing launch configuration, under BlackBerry Simulator, click a launch configuration.
To work with a new launch configuration, right-click BlackBerry Simulator, and click New.
Click the Simulator tab.
Click the General tab.
Click run
i have followed all the steps above but still i am getting the error failed to connect to the remote VM.Connection time out.org.eclipse.jdi.TimeoutException
can anyboby help me in this issue
Do you see this every time you launch your test?
This thread mentions:
For the 8530 simulator just try it again.
I get that message sometimes when I am running too many apps/low memory (I do a lot)/just started Eclipse/etc.
Often if I run it a second, sometimes third time it works and continues to work after that.
