Exception in thread "main" java.lang.UnsupportedClassVersionError: com/android/prefs/AndroidLocationsProvider has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
I tried also JDK 11 but it doesn't works.
How do I fix?
This error is telling us that our class was compiled at a higher version of Java than the version with which we tried to run it. More specifically, in this case we compiled our class with Java 11 and tried to run it with Java 8.
we have two ways we can resolve this error: compile our code for an earlier version of Java, or run our code on a newer Java version.

This is the said error:
Error: LinkageError occurred while loading main class net.javaguides.sms.StudentManagementSystemApplication
java.lang.UnsupportedClassVersionError: net/javaguides/sms/StudentManagementSystemApplication has been compiled by a more recent version of the Java Runtime (class file version 62.0), this version of the Java Runtime only recognizes class file versions up to 61.0
You need to have a newer java as runtime, or compile for an older version.
The error
java.lang.UnsupportedClassVersionError: net/javaguides/sms/StudentManagementSystemApplication has been compiled by a more recent version of the Java Runtime (class file version 62.0), this version of the Java Runtime only recognizes class file versions up to 61.0
Indicate that your runtime is Java 17 (version 61.0), and the StudentManagementSystemApplication classes are compiled in Java 18, (version 62.0.)
Update de your java runtime and check if there is any other error
This is my first application that i try to execute exe.
I'm using launch4j to do this. After executing and trying to run, I get this error:
Blockquote
Launch4j - Exception in thread "main" java.lang.UnsupportedClassVersionError: FakeMain has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
I searched something about versions of java, so I checked my versions of java and they are the same.
That's my versions of java:
My versions of java in cmd
Maybe I did something wrong there?

I don't know what I can do. I spend all this day about fix this and nothing.
Error after try to run exe file
You have compiled the code with Java 11 as target. But your PC want's to execute the Java Code with Version 8, which is not possible.
Make sure you have installed the correct Versions and also make sure that the executable uses Java 11.
Here you can find the Java Versions mapped to the Runtime Versions: Java Version Numbers
The Article gives you also some information about how to compile and execute for the correct versions.
I wanted to use JavaFX to start doing an interface to my app but I get error:
java.lang.UnsupportedClassVersionError: org/openjfx/gradle/JavaFXPlugin has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
> org/openjfx/gradle/JavaFXPlugin has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
Can someone please explain me how to fix it for IntelliJ Idea?
Thank you!
It says that your current version of Java only recognises class file version up to 52.0. This means you have Java 1.8 (version 8) installed on your system.
Simply install Java version 11 to remove the error. Or if you already have Java 11 installed, then check your project's JDK path and make sure that you've configured JDK 11.

I'm trying to use visual studio code for Java.
Have installed the extensions for Java, and have a 1.8 JDK installed with environment variable pointing to the install.
When starting debugger with a simple hello world program, I get the following:
java.lang.UnsupportedClassVersionError: HelloWorld has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0
at java.lang.ClassLoader.defineClass1(Native Method)
......
......
at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:495)
Any help with getting Java debugging in Visual Studio code appreciated.
You are probably compiling (or using dependencies compiled) with java 9, but still using JDK 8.0
Install java 9 and change your OS environment settings to point to the new JDK. This should solve your problem.
