I have a jar file and when I double click on it , it responds nothing. My OS is windows 10 and I have followed the steps in the picture. Does windows 10 has any exception or I'm doing the wrong way?

I'm expecting out like the one in the pic. I have checked with regedit procedure and also I have used the tool jarfix, but I didn't get the output i.e jar is not opening.

It's a command line app?
If so (and someone might correct me if I'm wrong) I'm fairly sure the default app for launching java on windows (javaw) does not produce a command line.

It's a small project having interaction between database and java program. I'm able to run through command prompt. I want the same work done when double clicked on the jar file.

Like Dave said, javaw.exe doesn't spawn a command line prompt. java.exe does, but the command window will disappear as soon as the program has finished running, so you should usually put a readLine() statement at the end of your program so the user has the chance to see the output.

Sorry, I just want to show an output. Actually to show correct output I need to set different values for 5 claasses in Test class.

I have kept readLine() statement at the end of my program and also associated my jar file with java.exe but still when I double click the jar file It's just opening and closing in less than a second. When I type java -jar First.jar in command prompt its working fine (console is waitng for user to enter something).
