Problem using NetBeans on Ubuntu

I installed NetBeans IDE 10.0, in which Netbeans is at 8.3 Patch 2,
alongside the JDK v 11.0.4 on Ubuntu 5.0.0-27. Create a new Java
application, say HelloWorld. The generated app will neither build nor run.


The generated source program (HelloWorld.java) contains just this (not
counting comments):

package newhello;
public class HelloWorld {
     public static void main(String[] args) {
     }
}
 
The initial package statement is flagged because the IDE says it can't
access java.lang. The Projects pane lists "JDK 11 (Default)" under the
Libraries but nothing underneath that folder. The String declaration is
flagged as "can't find symbol". Alt+Enter offers no suggestions for how to
fix either problem.

Nope, if you’re doing the above, you’re not using 11.1.

I wouldn't dignify a throwaway program like this as an "application"  😊

Thanks Neil.  I was starting to wonder if all of the Applet stuff we have
lived through was a dream.

Did not say nightmare because it wasn't necessarily bad, just a part of
history. :)
