I'm here to talk to you about a problem I got today working for the first time whit this new class called "Robot" of the library java.awt.
I must say Robot works fine, but troubles come every time i stop the application. My keyboard doesn't recognize any command and when i try to write something, random Windows appear everywhere,
as if the keyboard no longer recognizes the predefined keys. is there anyone who knows the reason for this strange behaviour and knows how to solve these issues?
thank you very much!
thankyou MadProgrammer, your observation was right! I solved my problem.
I'm sorry I didn't provide an example related to my question but I was sure that someone would nave understood my problem.

I'm trying to solve Google's foobar challenges. I'm not going to spoil the actual question for anyone else, but the title is "Save Beta Rabbit". My solution is coded in Java, and every time I try to verify it I get an Error(400): Bad request. This appears to be an error on their part. I've tested the code locally on my machine and it works fine. Also, if it was a problem with runtime or memory, foobar explicitly tells you that. It also explicitly tells you when you have complier errors. Anybody know anything about this? Challenge is on a timer here.
UPDATE: I've traced down where the bug is. When you recursively call the same static method twice, the bug occurs. Unless anyone else has seen this before, I'm going to report it to Google through the feedback mechanism and close this question.
I got the same error in a Java solution. Without getting into implementation details, it turns out it was a performance problem. After I fixed it the verifier worked.
Every time I run certain GUI interface excercises using swing the program works perfectly but something is wrong with what I suspect might be the jdk or something as it also happens like this on Eclypse.
It first appears to show correctly but with mouse over or when entering data in a textfield it all shows distorted.
Has anyone encountered these problems?
I managed to fix the problem re-installing the drivers to my graphics card!
Thank you.
Hope this helps anyone in the future with the same issue
Okay I haven't had a problem with NetBeans in the past. It's my preferred IDE because it will put an error notification type thing next to a line of code that is wrong. Example would be if I forgot a semicolon or accidentally put Jlabel instead of JLabel. Somehow last night it stopped doing that for me. I think maybe I pressed a button or accidentally changed a setting(Or maybe I need to update it?).
Anyway, if anyone knows how to fix this please let me know as if makes error catching take longer.
Thanks in advance!
Please update your NetBeans installation.
There were some issues regarding error highlighting recently, but they should be fixed now.
I'm having this issue in my MATLAB program.
I want to perform a set operation on my UI during a coding. In other words I'm pressing a button to launch my code and at the same time I want to change some uicontrols.
I tried with pause and wait with no luck.
I'm pretty sure that MATLAB gives priority to my coding part intead of the Java interface.
Anyone has any idea? Thanks
Thanks to nick I solved adding
waitnow; pause(.1);
Guys, unbelievable, that works on linux/OSX but not under windows..that's so weird
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...
