Cannot resolve symbol 'System

你提到的 "Cannot resolve symbol 'System'" 是一个编译错误，通常出现在Java编程中当你试图引用 `System` 类而IDE（如IntelliJ IDEA、Eclipse等）无法找到这个类的时候。`System` 是Java的一个内置类，用于访问操作系统的一些功能，例如控制台输入输出。

如果你看到这个错误，可能是以下几个原因导致的：
1. 未导入 `java.lang` 包：`System` 属于该包，如果忘记添加 `import java.lang.System;`，就会报错。
2. 文件路径或命名冲突：如果有同名的类或变量覆盖了 `System`，也会引发这个问题。
3. 编程环境配置问题：确保你的项目设置正确，包括库依赖和构建路径。

修复这个错误后，你应该就能正常使用 `System` 类的功能了。

Cannot resolve symbol 'System'

If you are encountering the "Cannot resolve symbol 'System'" error, it usually means that the System class from the Java standard library is not being recognized by your code. This can happen if you forget to import the necessary packages or if there is an issue with your project setup.

To resolve this issue, you can try the following steps:

1. Check your import statements: Make sure you have the following line at the top of your code file:

   import java.lang.System;

2. Make sure you have a valid JDK (Java Development Kit) installed on your system: The JDK includes the necessary libraries, including the System class. Ensure that your JDK installation is properly configured and accessible to your development environment.

3. Clean and rebuild your project: Sometimes, build errors can cause issues with symbol resolution. Try cleaning and rebuilding your project to see if it resolves the problem.

4. Verify your project setup: Ensure that your project is correctly set up in your IDE or build tool. Make sure that the JDK version configured for the project matches the one you have installed.

If none of these solutions work, please provide more information about your project setup, such as the IDE or build tool you are using and any relevant code snippets, so that I can assist you further.

cannot resolve symbol 'system'

这个错误信息通常在编译或者运行Java程序时出现。它的意思是无法解析符号“system”，因为Java大小写敏感，正确的是小写的“system”。在Java中，标准输出通常使用小写的“System.out.println()”语法，而不是大写的“system.out.println()”。因此，您应该检查您的代码，确保所有的Java关键字、类名和方法名的大小写都正确无误。
