Java is a class-based, general-purpose, object-oriented programming language which is created for puspose to have fewer implementation dependencies. It is an application development platform for computers. “Java.lang.unsupportedclassversionerror” is a common error that shows up in many ways. What is the cause of it and how to fix it? Let’s read this article to find the best answer for it.
When do you get the error “java.lang.unsupportedclassversionerror”?
You will see problems like the ones below when you are attempting to start a Mule application:
java.lang.UnsupportedClassVersionError: CLASS_NAME : Unsupported major.minor version CLASS_VERSION
You have got “java.lang.unsupportedclassversionerror” error because of Java version incompatibility. It occurs when projects are built using a higher version of Java (for example JDK 1.8 version) and subsequently run on a lower version (for example jdk 1.7 version).
How to fix “java.lang.unsupportedclassversionerror” error?
Option 1: compile to an older or a more recent Java version
To solve the error “java.lang.unsupportedclassversionerror”, you have the option of compiling your code for an older Java version or running it on a more recent Java version. Only your decision is relevant here. If a third-party library is used, it is best to run on a newer Java version, but it is best to compile to an older version if it is intended for distribution.
Option 2: Utilize JAVA_HOME Environment Variable
Utilizing JAVA_HOME Environment Variable is a great solution for you to handle with your problem. Let’s check the setting of the JAVA HOME option first. You can see which JDK is being used by running javac from the command line by looking at this:
echo %JAVA_HOME% C:\Apps\Java\jdk8-x64
You can download the newer version and make sure your PATH and JAVA HOME environment variables are properly set if you’re prepared to switch completely to a newer JDK.
Option 3: Use the Java edition
To solve the problem, you also can use the Java edition that the class throwing the problem requires. Which Java version corresponds to each class version can be found. Even though Anypoint Studio 7 includes the embedded JDK, the computer should also have a JDK version that is compatible with Studio. The three versions that are most frequently used are Java SE 8 (class version 52), Java SE 11 (class version 55) and Java SE 7 (class version 51).
Option 4: Operate a New JRE
The Java Runtime Environment’s components are used by both the Oracle GoldenGate Director software and installation (JRE). Many times, this environment is already in place since it was set up during the configuration of the system or the installation of another program.
Let’s go back to your example and examine how you can fix the problem by running Java at a higher version. The java command that comes with Java 11 JRE can be used to execute your code if it is located in C:Appsjdk-11.0.2:
C:\Apps\jdk-11.0.2\bin\java com.ittutoria.MajorMinorApp Hello World!
The solutions mentioned above are very useful for you to solve the error “java.lang.unsupportedclassversionerror”. Let’s use them to get your desired results. They will help your program run well without any errors.
