java.lang.UnsupportedClassVersionError

How to resolve this “java.lang.UnsupportedClassVersionError” error ?
This exception can occur when the source is built targeting a JDK that is not supported by the JDK attempting to run it.
For example, if an application is built targeting only JDK 1.5,  and we try to run it using JDK 1.4, the above exception will occur.

  1. Good stuff, by the way some time its not easy to shift to higher version of JDK due to some other dependency and best approach is to find the culprit classes or jar and get the compatible version of those jar based on your execution environment to avoid unsupportedclassversionerror.

It teaches about packages and streams and creating a web server with the Express framework.LibUVThis is the official documentation of the supporting C++ code of the Node.js runtime.V8This is the official documentation of the JavaScript engine that makes it possible to write Node.js with JavaScript. x
