Unsupported major.minor version 52.0 [duplicate]

Answer 1

Unsupported major.minor version 52.0 comes when you are trying to run a class compiled using Java 1.8 compiler into a lower JRE version e.g. JRE 1.7 or JRE 1.6. Simplest way to fix this error is install the latest Java release i.e. Java 8 and run your program.

Answer 2

The smart way to fix that problem is to compile using the latest SDK and use the cross compilation options when compiling. To use the options completely correctly requires the rt.jar of a JRE (not JDK) of the target version.

Given the nature of that applet, it looks like it could be compiled for use with Java 1.1.

Answer 3

All you need to do to solve the problem is... to make sure your version of Java is the same for both compiling and running. No matter what tools or IDEs you are using.

Answer 4

This occurred to me when I installed a fresh Java 1.8, but left the old command line interpreter open.

It had an old path and kept on executing the application with Java 1.7 whereas project was already built with Java 1.8.

Answer 5

Just go to http://java.com/en/download/ and update your version of JRE

Answer 6

Upgrade your Andorra version to JDK 1.8.

This is a version mismatch that your compiler is looking for Java version 8 and you have Java version 7.

You can run an app build in version 7 in version 8, but you can't do vice versa because when it comes to higher levels, versions are embedded with more features, enhancements rather than previous versions.

Download JDK version from this link

And set your JDK path for this
