In this post, we will see how to list all files in a directory in Python. There are multiple ways to list all files in a directory in Python. Table of Contents [hide] Using os.walk Using os.listdir(path) Using glob Conclusion Using os.walk Python os module provides multiple function ...
1.File 类的 list() File 类的 list() 方法提供了遍历目录功能,该方法有如下两种重载形式。 String[] list() 该方法表示返回由 File 对象表示目录中所有文件和子目录名称组成的字符串数组,如果调用的File 对象不是目录,则返回 null。 提示:list() 方法返回的数组中仅包含文件名称,而不包含路径。但不保证所得...
The first example lists the current directory. Main.java import java.io.IOException; import java.nio.file.Files; import java.nio.file.Paths; void main() throws IOException { var path = Paths.get("."); try (var files = Files.list(path)) { files.forEach(System.out::println); } } ...
List directory contents recursively with Files.walkThe Files.walk method returns a lazily populated stream of Paths by walking the file tree rooted at a given starting file. Files.walk recursively walks all subdirectories. Main.java import java.io.IOException; import java.nio.file.Files; import ...

Java can help reduce costs, drive innovation, & improve application services; the #1 programming language for IoT, enterprise architecture, and cloud computing.
上述代码中,首先通过File类创建一个表示目录的对象directory,然后调用iterateFiles方法来迭代读取目录中的所有文件。在iterateFiles方法中,首先判断当前文件是否为目录,如果是目录,则递归调用iterateFiles方法来处理该目录;如果是文件,则进行相应的处理(在示例代码中,只是简单地打印文件的绝对路径)。 这样,通过递归调用,可以遍...
