  • Aside from `Console` tab there is also `Problems` tab. Take a look at what is listed there. – Pshemo May 03 '20 at 13:50
  • Please [edit] your question and post the **text** of the error message. I can't even read what it is in the screen capture. Also post your code as **text**. – Abra May 03 '20 at 14:13

  • In the screen capture of the _Problems_ tab, the following appears: _Project ... is missing a required library_ It's hard for me to help you if I don't know what library is missing. You can change the size of the columns in the table by placing the mouse on the line separating the columns and dragging the mouse. – Abra May 04 '20 at 04:12

It looks like that your application is not compiled, or even if it's compiled java doesn't start it. Make sure to build the application before launch, or try exporting it to jar file, then look at the jar file if it has the classes.
