java.util.arrays 无法解析

Question

我有一个运行良好的春季项目。 我更新了我机器上的java平台（通过自动的java更新通知）

更新后，我在编码时出现蓝屏，现在我无法在 Tomcat 上部署解决方案，因为我一直遇到此错误：

当我检查控制器时，我发现： import java.util.Arrays; 在我的项目中现在无法解决！

对解决这个问题的一点帮助将不胜感激！

谢谢！

这可能是一个漫长的过程，但由于您在此之前出现蓝屏，因此可能是 Java 安装已损坏。创建一个新的基础项目并尝试使用其中的Arrays，如果问题仍然存在，请重新安装Java；如果不是你有一些配置问题，它可能来自 Maven 或类似的，如果你正在使用这些。
