Solution

You can install the gnome-system-monitor on Lubuntu:

sudo apt-get install gnome-system-monitor  

If you are looking for a lightweight alternative you can use Conky:

sudo add-apt-repository ppa:teejee2008/ppa
sudo apt-get update
sudo apt-get install conky-manager

I already did that.My main class is "mygridlayout.MyGridLayout".

[Arvind Katte]

try these steps Close netbeans and then delete this directory C:\Users\Your name here\AppData\Local\NetBeans\Cache Start Netbeans again and let it read the project. Test project. Run project. It should work fine.

[Mandip Panta]

Did that but still getting the same error but other programs are working fine.

[Arvind Katte]

try this last step Right click project > properties > run > browse for main class. or else rename the package name

[Arvind Katte]

this is the final step, Actuall, when you click the "Run" button on top of the netbeans window, it only run the application's main class . but this Sequence class is not the main class of the project most probably. for this case to run this class you have to right click on Sequence class editor and select Run or Run as menu. Then this class will be executed on separate console, I hope this will work ..
