If I open or create a new project for java in Netbeans 8 it shows nothing only a blank tab, the code is missing. Then I try to use a different version, the Netbeans 13 with JDK 18 it still has the same problem. I don't know what goes wrong the installation is fine though. I try to create another project in html5 in Netbeans 13 and it works fine. What should I do?
