Java文件用exe4j导出后的bug

Question

我用exe4j导出了一个exe，打开出现了bug：
java.lang.UnsupportedClassVersionError: game/Main has been compiled by a more recent version of the Java Runtime (class file version 60.0), this version of the Java Runtime only recognizes class file versions up to 52.0

怎么办啊？

Answer 1

你的代码是用 JDK 16 编译的，没办法运行在 JDK 8 上面，可以把代码编译的版本改成 JDK8 或者将运行环境改成 JDK 16。
