Question
I made a .jar file using NetBeans and when I try to run it on a different PC, it giver me this message:
It isn't a typo or anything because I made several other .jar files and got the same response. If the code matters, then here is the code:

someone please help me. this problem is limiting my java programs
Solution
The java version that you compile with should be less than or equal to the java version that you are using to execute.
For ex if you compile something with Java 1.7.1 , it can only run on JRE's 1.7.1 and higher. It will fail with the same exception if you run it on java 1.7.0
OTHER TIPS
That's a java version mismatch.
It looks like the jar file you created was build for Java 8.
Try using JRE 8.0 and see if it works.
4 months before even i faced similar issue, this is because of the java minor version mismatch. We developers may be under conception only mismatch happens between 1.6 and 1.7 versions. But it happens between minor versions like 1.7.1 and 1.7.20 also. Please check it.
