检查文件是否隐藏在Java中

Java中 File 类的 isHidden() 方法可用于检查文件是否隐藏。此方法返回一个布尔值——真或假。

句法：

public static boolean isHidden(Path path) 
throws IOException

参数：要测试的文件的路径。

返回类型：布尔值，如果发现文件隐藏则返回 true，否则返回 false，因为未发现隐藏文件

抛出的异常：

• IOException：如果发生 I/O 错误
• SecurityException ：在默认提供程序的情况下，并且安装了安全管理器，将调用 checkRead() 方法来检查对文件的读取访问权限。

Remember: Depending on the implementation the isHidden() method may require to access the file system to determine if the file is considered hidden.

例子：

Java

// Java Program to Check if Given File is Hidden or Not
// Using isHidden() Method of File class
 
// Importing required classes
import java.io.File;
import java.io.IOException;
 
// Main class
// HiddenFileCheck
public class GFG {
 
    // Main driver method
    public static void main(String[] args)
        throws IOException, SecurityException
    {
 
        // Creating a file by
        // creating an object of File class
        File file = new File(
            "/users/mayanksolanki/Desktop/demo.rtf");
 
        // Checking whether file is hidden or not
        // using isHidden() method
        if (file.isHidden())
 
            // Print statement as file is found hidden
            System.out.println(
                "The specified file is hidden");
        else
 
            // Print statement as file is found as not
            // hidden
            System.out.println(
                "The specified file is not hidden");
    }
}

输出：

输出说明：从输出的背景可以很容易地看到“demo.rtf”文件弹出图标清晰可见。如上所示，该代码反映了特定文件未隐藏在终端输出中。

Note: The precise definition of hidden is a platform or provider-dependent.

• UNIX: A file is hidden if its name begins with a period character (‘.’).
• Windows: A file is hidden if it is not a directory and the DOS hidden attribute is set.
