问题
当我运行我的 HelloWorld 程序时,它返回:
"java.lang.UnsupportedClassVersionError: HelloWorld has been compiled by a more recent version of the Java Runtime (class file version 52.65535), this version of the Java Runtime only recognizes class file versions up to 52.0 "
如何解决这个问题?

public static void main(String[] args) {
System.out.println("123");
}
}
