Fixing java lang UnsupportedClassVersionError in Java

Question

I am using Notepad to write, edit the Java code. But when I am running this code, I am getting java.lang.UnsupportedClassVersionError. How to fix it?

Answer 1

To fix the exception/ error, you should try to either run the Java code with a newer version of Java JRE or specify the target parameter to the Java compiler to instruct the compiler to create code compatible with earlier Java versions.
