project/2
├── one.txt3
└── directory2/4
| └── two.json5
└── directory3/6
└── three.htmlxxxxxxxxxx1
import java.io.File;2

public class Example {4

public static void listFilesInDirectory(File directoryPath) {6
File[] filesList = directoryPath.listFiles();7
for (File file : filesList) {8
if (file.isFile()) {9
System.out.println(file);10
} else {11
listFilesInDirectory(file);12
}13
}14
}15

public static void main(String[] args) {17
File directoryPath = new File("C:\\project");18
listFilesInDirectory(directoryPath);19
}20
}Output:

Integer.MAX_VALUE, // the maximum number of directory levels to search10
(filePath, FileAttributes) -> FileAttributes.isRegularFile())11
.forEach(System.out::println);12
