Answer 1

I had the same problem in Windows 10. I fixed it using righ-click on the "helloworld.jar" and go to properties and click on change button under "Opens with:" and select "Look for another app on this PC". In the "Open with..." dialog box, go to your Java folder location on your PC and open corresponding jdk folder and then open the bin folder and select "javaw.exe" from there. Then next time your "helloworld.jar" will open the normal way.

Usual java location example : "C:\Program Files (x86)\Java\jdk1.8.0_111\bin".
