unsupported class file major version62

This error message typically occurs when you are trying to run a Java class file that was compiled with a higher version of the Java Development Kit (JDK) than the one you are currently using.

The number "62" in the error message refers to the major version number of the JDK used to compile the class file. Each version of the JDK has a unique major version number, and the major version number of the JDK you are using must be equal to or greater than the one used to compile the class file.

To resolve this error, you need to either upgrade your JDK to a version that supports the class file's major version number, or recompile the class file with a lower version of the JDK.
