All files under the JAVA Traversal folder (recursive calls and non-recursive calls)

all files under the JAVA Traversal folder (recursive calls and non-recursive calls)

1. Do not use recursive method calls.

public void TraverseFolder1 (String path) {int filenum = 0, foldernum = 0;        File File = new file (path);            if (file.exists ()) {linkedlist<file> list = new linkedlist<file> ();            file[] files = file.listfiles (); for (File file2:files) {if (File2.isdirectory ()) {System.out.println ("folder:" + file2.                    GetAbsolutePath ());                    List.add (file2);                filenum++;                    } else {System.out.println ("file:" + File2.getabsolutepath ());                foldernum++;            }} File Temp_file;                while (!list.isempty ()) {temp_file = List.removefirst ();                Files = Temp_file.listfiles (); for (File file2:files) {if (File2.isdirectory ()) {System.out.println ("folder:")                        + File2.getabsolutepath ());  List.add (file2);                      filenum++;                        } else {System.out.println ("file:" + File2.getabsolutepath ());                    foldernum++;        }}}} else {System.out.println ("file does not exist!");    } System.out.println ("folder total:" + foldernum + ", file total:" + filenum); }

2. Use recursive method calls.

public void TraverseFolder2 (String path) {        file File = new file (path);        if (file.exists ()) {            file[] files = file.listfiles ();            if (Files.length = = 0) {                System.out.println ("folder is empty!");                return;            } else {for                (File file2:files) {                    if (file2.isdirectory ()) {                        System.out.println ("folder:" + File2.getabsolutepath ());                        TraverseFolder2 (File2.getabsolutepath ());                    } else {                        System.out.println ("file:" + File2.getabsolutepath ());}}}}        else {            System.out.println ("file does not exist!");}    }

public static list<file> getfilelist (String strpath) {        file dir = new File (strpath);        file[] files = dir.listfiles (); The files in the directory are all placed in the array if (Files! =        null) {for            (int i = 0; i < files.length; i++) {                String fileName = files[i]. GetName ();                if (Files[i].isdirectory ()) {//Determines whether the file or folder                    Getfilelist (Files[i].getabsolutepath ());//Gets the file absolute path                } else if ( Filename.endswith ("avi")) {//Determine if the file name ends with an. avi                    String strFileName = Files[i].getabsolutepath ();                    SYSTEM.OUT.PRINTLN ("---" + strfilename);                    Filelist.add (Files[i]);                } else {                    continue;}}        }        return filelist;    }
