I have a MacBook Pro. The case that I installed NetBeans latest version and Java JDK, finally I installed the necessary tools.
The problem is that, when I compile, I never open the terminal or the project ... if I make a print "hello" shows it below, and I want it to open the console (terminal)
If I put a JFrame, more of the same, it does not open the Java file.
In fact the tab that is shown in the lower part is the output console of your developments, as such, you could say that it is like your CMD, Terminal or whatever you use, maybe you could try to locate the path of your project and from there run the jar / war / ear generated and ready.
The other option would be to configure your Maven or Ant, depending on what you use to perform post-compilation tasks, for example that Terminal is launched with "X" command.
