java读取文件夹下文件名 再按行写入txt文件

public class Getpicname {    public static void main(String[] args) throws SQLException {        try {            File file = new File("C:/Users/Desktop/照片/结果");  //一个图片文件            FileWriter fileWriter = new FileWriter("C:/Users/Desktop/照片/picname.txt");            String[] filelist = file.list();            for (int i = 0; i < filelist.length; i++) {                System.out.println(filelist[i]);    //打印到控制台显示文件夹下全部文件名                fileWriter.write(filelist[i] + "\r\n");  //换行写入txt文件中                //fileWriter.newLine();//换行            }            //注意关闭的先后顺序，先打开的后关闭，后打开的先关闭            fileWriter.flush();            fileWriter.close();            System.out.println("OK，It's End!!!!");        } catch (Exception e) {        }    }}
