kill all netbeans processes at once

Hello

My question is not directly linked to programming, but it is related and I think it will help a lot of people.

The problem is this: I'm working with server and sockets in Netbeans and every time I run tests I open 5 or more threads.

When I close them, I have to click on the "x" of each one, and then confirm the action.

Nothing very serious, but after 2 hours of testing, I'm sick of having closed about 200 processes 1 for 1 hehe

Is there a shortcut that will close all processes currently running ??

I am referring to the following processes (Netbeans print):

Thanks
