I am stuck on the following error. I don't know what type of error it is. What should I do?
C:\Users\shehzad\Desktop\Software>java -jar Untitled.jar Exception in thread "main" java.lang.UnsupportedClassVersionError: FrontEnd/MainWindow : Unsupported major.minor version 52.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$100(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader.main(JarRsrcLoader.java:56)
Scenario is: I developed software that works fine in Ubuntu 14.04 Lts. It's JAR also works in Ubuntu, but when I tried this JAR in Windows 7 it shows the above error.
Ubuntu Java version: 1.8.0_101
Windows Java version: 1.7.0_79
