There is nothing wrong with my title,but its true.When i run my Java NetBeans in the morning, it works fine.But in evening/night (without switching off my lappy/neatbeans), there is little problem.
When i try to run any program, it won't show me the modified Output of my program.
Suppose, in my program say 'A' i have a print statement say print("hi"), and when i change this to: print("bye") and run the program, it will show me "hi" not "bye".
It will show me "bye" at the 2nd run time.
I don't know whether this question will be closed or something, but this is real.Has anyone experienced any thing like that?Is this beacuse of :
1)My lappy is on from morning till late nignt,can this cause any problem?
2)My NetBeans is opened from morning till late night (any memory problems, or something?)
Note: It works fine it the morning time, please help me to find out the bug, it really irritates alot.
UPDATE:
Using Windows 7, NB 6.5.1
You could try deleting the cache (under C:\Users\yourUserName\AppData\Local\NetBeans\Cache\YourVersionOfNetBeans and delete it's contents.
Then do a clean and build
try to, clean and build After you make any change in your code. You may have changed the auto save option.
The 2 probable causes you mentioned at last are not valid at all.

I am using Android Studio 4.1.1. windows 7. I write in Java. I noticed this feature of the program. Changing something in code, layout or resources. I run the program and see that my changes have not appeared! First comes the thought that I was wrong somewhere. I start looking for an error. I don’t find it. I run the program again and it already works as it should. Now I'm used to it. The larger the program, the more often this happens. To be sure of the result, you have to run the program twice each time, because I'm not sure if this time all the changes took effect. It is very uncomfortable. Tell me why this is happening and how to solve this problem.
Problem
My code runs without problem but this prompt keeps appearing. I have run into this problem a lot but I just ignored it since the code runs fine. However it's starting to get rather annoying and all the fixes I saw online did not work. I suspect this has something to do with 'hot code replace'.
I also did set "Build automatically".
I saw on some other post that I could disable hot code replace by going to Preferences>Run/Debug, but I found no such option.
Any help is appreciated, thanks!
Apparently I was running in debug, I confused my shortcut keys... Problem fixed lol
I am trying to set up a java project and so far everything is working as one can see in this screenshot:
However when i adjust my code, the console does not update as wel as we can see here:
I tried to check path -> build automatically and clean the project but this does not work. I also terminated the console and restarted it but this did not help as well. Anyone can help me with this problem?

The answer was actually quite easy. I assumed Eclipse automatically saves your changes when re-running the console but this was not true. Thus when i just save the file it runs perfectly fine. Can't believe I spend a hour not figuring this out.

I have recently started learning android development, and I just built an app that changes color and text based on pushing buttons and gestures. It ran fine on my phone (Yay!), but then on my second run, an error occurred. When hitting the "run" button, an edit configurations window opened up:
I also noticed, that on the side where my project tree should be is this instead:
I don't think there is an issue in the code because it was running fine before, but I would be happy to post the code if needed.

I dont know if this was the reason, but i'll include this anyway, I tried changing the name of my project, but it wouldn't work, but I changed it back. I included this in my question because that's literally the only thing I did before this error occured.
Thank you so much for helping out a fellow programmer, I really appreciate it. I have been looking at many other forums (for some hours) about this topic, but still couldn't trouble shoot this problem. It seems kind of odd that it was working first, and then it just randomly stopped working. I cant wait for your response!
Here is the dropdown for Module:
As you can see, that is the only option.
Are you sure you are opening the project as android gradle project ?
Try to import the program not open it
I am very new to Eclipse, java programming and well all "programming" in general and I have recently been learning how to use Eclipse. I've been using it for about a week now and it has been going decent so far. Apart from some errors,(mostly on my part) that has been fixable by restarting the program itself.
However when I started using it today I could no longer see the suggestions made from the Quick Fix command, for example if I type findVi and then press CTRL+1, it shows "No suggestions available" instead of "findViewById()" or something similar.
I know it's the correct binding, I even reset the keys to default to be sure. It still finds the ID if i type it manually but I would like to able to finish words faster that way.
If you guys got any suggestions that can help me out, please let me know.
Thanks.
- First of all if you are new with Java, and want to practice Java, you should NEVER USE ANY IDE, that way you learn the proper syntax, and it helps your error finding skills.
- But as you wrote "findViewById()" it seems that you are doing Android, Now this happens sometimes that Eclipse behaves weirdly with Android. Thats the reason when you make any changes into your Eclipse GUI while working with Android, its always better to see if those changes have taken effect.
- This problem usually goes off after closing and re-opening the Eclipse once or twice.
- Ok try this....
Type findVie then press Ctrl + Space-Bar See if the suggestion pops up...
You can access the Content Assist preferences from Window > Preferences > Java > Editor > Content Assist... perhaps something got messed up.
