UnsupportedClassVersionError how to solve
In this video, I’m going to show the famous UnsupportedClassVersionError, e.g. below. Why it happens and how to solve it.
Exception in thread "main" java.lang.UnsupportedClassVersionError: HelloWorld has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognises class file versions up to 52.0
We have two solutions:
1. compile our code for an earlier version of Java ;
2. run our code on a newer Java version ;
If you have this problem with a JAR, you have two solutions:
1. If the jar is yours, compile the project/jar to your JVM version using source/target or release;
2. If the JAR isn't yours, you'll have to use a newer version of the JDK;
