该类已由Java Runtime的较新版本编译

Question

所以我有一个项目，要求我用Java创建程序。由于我们是该语言的新手，所以老师建议我们用Notepad ++编写代码，然后键入“ javac Filename.java”和“ java Filename”来运行它。问题是即使编译成功，当我实际尝试运行程序时，也会发生以下错误：

Error: A JNI error has occurred, please check your installation and try
again
Exception in thread "main" java.lang.UnsupportedClassVersionError:         Products 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

即使我和我的一个朋友具有相同版本的JDK（11.0.2），我的程序似乎仍可以在他的计算机上正常运行，没有任何错误。
