The code has been compiled with and for Java 8

You need to run with Java 8 too.
您也需要使用 Java 8 运行。

This error is probably because you are using Selenium 3.3.1with Java 1.7you need to upgrade java version to Java 1.8OR
it could mean that your java compiler setting doesn't match with your project settings, In that case you have to goto :
此错误可能是因为您正在使用Selenium 3.3.1withJava 1.7您需要将 java 版本升级到Java 1.8OR 这可能意味着您的 java 编译器设置与您的项目设置不匹配，在这种情况下，您必须转到：
Project > Properties > Java Compiler > and select java version to the one you're using in your project as follow:
项目 > 属性 > Java 编译器 > 并选择您在项目中使用的 Java 版本，如下所示：

The exception is generated from java.lang package, please take care of these observations. Because the java.lang.UnsupportedClassVersionError tells you this has nothing to do with selenium. That is probably why your question looks like duplicate and in risk of getting removed. You can check for a solution in the given possible duplicate link.
异常是从 java.lang 包产生的，请注意这些观察。因为 java.lang.UnsupportedClassVersionError 告诉你这与 selenium 无关。这可能就是为什么您的问题看起来重复并且有被删除的风险。您可以在给定的可能重复链接中检查解决方案。
According to your given data, you have jdk8 and jre7 versions. You need to be having either jdk7-jre7 or jdk8-jre8 pair. If your code was compiled in a higher version jdk (8) and the .class files are being run in lower jre (7), this is to be expected.
根据你给出的数据，你有 jdk8 和 jre7 版本。您需要拥有 jdk7-jre7 或 jdk8-jre8 对。如果您的代码是在更高版本的 jdk (8) 中编译的，并且 .class 文件在更低版本的 jre (7) 中运行，那么这是意料之中的。
So check your project settings from kushal's answer. or compile directly with a compatible/desirable jre version (from https://stackoverflow.com/a/11432195/2453382)
因此，请从 kushal 的回答中检查您的项目设置。或直接使用兼容/理想的 jre 版本编译（来自https://stackoverflow.com/a/11432195/2453382）
