Your minecraft files were compiled with Java 16 and you have installed and configured only version Java 8. You need to install and configure Java 16: https://www.oracle.com/java/technologies/javase/jdk16-archive-downloads.html

Java 11 uses Class File Version 55 Java 8 uses Class File Version 52 This exception means that the java application or Java Class was compiled with Java 11 where Source and Target both compatibility was Java 11. So to resovle this issue, there are 2 solutions. 1 - Use Java 11 for compilation and for execution. 2 - When compiling change the Target Compatibility to Java 8. (This can be done in multiple ways.) a) Command: javac -source 11 -target 8 b) Maven: <maven.compiler.target>1.8</maven.compiler.target> c) Eclipse: Right Click on Project -> Properties -> Java Compiler -> Java Complience Level (Change to 1.8) D) Intellij: File -> Project Structure -> Project -> Language Level (Change to 1.8)

Upgrade your Java runtime: If possible, update your Java runtime environment to a version that supports class file version 60.0. You can download the latest version of Java from the official Java website (https://www.java.com). Recompile the application: If you have access to the source code of the application, you can recompile it using a compatible version of the Java compiler. Make sure you use a version that matches the Java runtime you have installed. Find a compatible version: If upgrading the Java runtime or recompiling the application is not feasible, you can try to find an older version of the application that is compatible with your Java runtime environment. Look for a version specifically compiled for Java versions up to 52.0. Remember to ensure compatibility between the Java runtime and the application you're trying to run to avoid this error.

use a older version of java to compile your program. Make sure your compiling version is lower or equal to the version your system is using. To check your java version use: java -version

The error message indicates that your Java Runtime version is too old for the class file you're trying to run. To fix this, you need to update your Java Runtime to a newer version that supports the required class file version. Visit the official Java website, download the latest Java version, install it, and then try running your program again.

The error message you're seeing indicates that you're trying to run a Java program (in this case, a Minecraft server) compiled with a newer version of Java than what you have installed on your system. The class file versions mentioned in the error (60.0 and 52.0) correspond to Java versions. For example, Java 8 uses class file version 52.0, while Java 16 uses class file version 60.0. To resolve this issue, you have a few options: Upgrade your Java version: Download and install a newer version of Java that supports the class file version used by the Minecraft server. You can download the latest version of Java from the official Oracle website or adopt OpenJDK. Recompile the Minecraft server: If you have access to the source code of the Minecraft server or have the ability to recompile it, you can do so using a Java compiler compatible with your installed Java version. Use a compatible Minecraft server version: Ensure that you are using a version of the Minecraft server that is compatible with the Java version installed on your system. Check the server's documentation or download page for information on Java compatibility.

The error message indicates that you are trying to run a Java application compiled with a newer version of Java than the one you have installed on your system. The class file version `55.0` corresponds to Java 11, while the class file version `52.0` corresponds to Java 8. This means that you are trying to run a Java 11 application on a Java 8 runtime environment. To resolve this issue, you have a few options: 1. **Upgrade your Java Runtime Environment (JRE)**: Install a newer version of Java (at least Java 11) on your system to be able to run the application. 2. **Recompile the application**: If you have access to the source code, you can recompile the application using a Java 8 compiler. This will generate class files compatible with the Java 8 runtime. 3. **Use a compatibility tool**: There are tools available that can help you run Java applications compiled with newer versions of Java on older Java runtimes, such as Retrolambda or Apache Retroweaver. However, these tools may not always work perfectly and may require additional configuration

The error message means that the Java program you're trying to run, specifically the com.example.demo.DemoApplication class, was made with a newer version of Java (version 55.0) than the one you're currently running (version 52.0). To resolve this issue, you'll need to update your Java runtime environment to a version that supports class file version 55.0 or higher. You can do this by installing a newer version of Java from the official Oracle website. Alternatively, if you're using a build tool like Gradle, you can update the Java version used for compilation to match the version you're running. This will ensure that the classes are compiled with a version that's compatible with your runtime environment.
