Hi - complete newbie - just installed JDK v 13 and created and run my first 'Hello World' java program. Great but I understand there should be a Java Control Panel. I am using Windows 10 - Nothing in Start, Control panel / Apps has Java SE v 13 icon but only option is uninstall, no javacpl in bin - completely lost - please help - thanks guys
There is no Java control panel, and none is needed.
The control panel was used in earlier versions of Java to handle browser integration and webstart caches mainly. As applets and webstart are no longer available, the need for the java control panel is gone, and it was removed.
You don't need it anyway to run your Java program.
