java - 如何使用Java将某个文件夹下的所有文件名添加到数组列表中

Question

到目前为止我已经有这么多了

 import java.io.File;
 import java.io.FilenameFilter;
 import java.util.ArrayList;
 import java.util.Arrays;

 import org.pdfbox.util.Splitter;
 public class fileName {
     public static void main(String args[]){
         File file = new File("/Users/apple/Desktop/");
         String[] directories = file.list(new FilenameFilter(){

             @Override
             public boolean accept(File current, String name) {
                return new File(current, name).isDirectory();
             }
         });
 System.out.println(Arrays.toString(directories));
 ArrayList<String[]>SSOList = new ArrayList<String[]>();
     }
 }

它打印我桌面上所有文件的名称，但我想将它们添加到数组列表中。我怎么做？

这很容易。您可以按如下方式使用递归:

 private static void read(final File folder)  {

    for (final File fileEntry : folder.listFiles()) {
        if (fileEntry.isDirectory()) {
            read(fileEntry);
        } else {
       //Do something
            }
    }
}
