Arrays.sort()方法对文件数组进行排序#xff0c;然后按照排序后的顺序遍历文件数组#xff0c;以按照文件名从大到小的顺序展示文件名

Arrays.sort()方法对文件数组进行排序然后按照排序后的顺序遍历文件数组以按照文件名从大到小的顺序展示文件名
public class FileSortExample {public static void main(String[] args) {File directory new File(path/to/directory);File[] files directory.listFiles();// Sort files in descending order by nameArrays.sort(files, (f1, f2) - f2.getName().compareTo(f1.getName()));// Print sorted file namesfor (File file : files) {System.out.println(file.getName());}}
}2按顺序
public class FileSortExample {public static void main(String[] args) {File directory new File(path/to/directory);File[] files directory.listFiles();// Sort files in descending order by nameArrays.sort(files, new ComparatorFile() {Overridepublic int compare(File f1, File f2) {return f2.getName().compareTo(f1.getName());}});// Print sorted file namesfor (File file : files) {System.out.println(file.getName());}}
}创建文件夹 File folder new File(path/to/folder);
if (!folder.exists()) {boolean success folder.mkdirs();if (success) {System.out.println(Folder created successfully!);} else {System.out.println(Failed to create folder!);}
} else {System.out.println(Folder already exists!);
}删除文件 if (file.exists()) {file.delete();}创建文件
if (!file.exists()) {// 逐级创建文件夹file.mkdirs();
}
