Problem in retreiving directory structure, code needs correction

Question

hello there
I am trying to fetch the directory structure of a particular directory in a way that the structure of subdirectories is also displayed.
I have the following code:
CODE:
import java.io.*;
public class FetchDir2
static File dirStruct[][] = new File[300][100]; //stores the directory structure at a particular level
static Integer pastIndex[] = new Integer[300]; //Stores index upto which a particular level has been scanned
static String path = "C:/trydir"; //path of user's workspace, change it accordingly
static int level = 0;
static int index = 0;
static int j=0;
static int i=0;
public static void main(String s[])
File fileTry = new File(path);
for(int i=0;i<300;i++)
     pastIndex=0;
fetchStr(fileTry);
public static void fetchStr(File fileTry)
dirStruct[level] = fileTry.listFiles(); //fetch list of files and directories at this LEVEL
sort(dirStruct[level]);
for(i=0;i<dirStruct[level].length;i++) //loop to scan each element at this level
if(dirStruct[level][i].isFile()) //if file is encountered
System.out.println("Level:"+level+"\t Index:"+pastIndex[level]+"\t DirStruct.Length:"+dirStruct[level].length);//CHKPOINT
     System.out.println("<file>"+dirStruct[level][i].getName()+"</file>"); //print file element
     pastIndex[level]++; //increase the index at this level by 1
//     if(dirStruct[level].length==0)
//     {break;}
//     else
     if(pastIndex[level]==dirStruct[level].length)
     System.out.println("</directory>");
     pastIndex[level]=0;
level--;
     if(level==-1)
          break;     
if(dirStruct[level][i].isDirectory())
System.out.println("Level:"+level+"\t Index:"+pastIndex[level]+"\t DirStruct.Length:"+dirStruct[level].length);//CHKPOINT
     String path = dirStruct[level][i].getPath();
     File f = new File(path);
     System.out.println("<directory>PATH:"+path);
     pastIndex[level]++;
     if(pastIndex[level]==((dirStruct[level].length)-1))
     pastIndex[level]=0;
     level--;
     System.out.println("</directory>");
     else
     level++;
     //System.out.println("</directory>");
     fetchStr(f);
public static void sort(File dirStruct[])
for(i=0;i<dirStruct.length;i++)
for(j=0;j<i;j++)
     int compare = dirStruct[i].compareTo(dirStruct[j]);
     if(compare>0)
     swap(dirStruct[i],dirStruct[j]);
public static void swap(File f1,File f2)
File f3;
f3=f1;
f1=f2;
f2=f3;
The dirctory structure used for testing is:
<dir trydir>
<file>f1</file>
<file>f2</file>
<file>f3</file>
<dir d1>
<dir d21>
<file>f</file>
</dir>
<dir d22>
<file>f</file>
</dir>
<file> f21</file>
<file> f22</file>
</dir>
OUTPUT:
Level:0 Index:0 DirStruct.Length:5
<file>a1.txt</file>
Level:0 Index:1 DirStruct.Length:5
<directory>PATH:C:\trydir\d1
Level:1 Index:0 DirStruct.Length:4
<directory>PATH:C:\trydir\d1\d21
Level:2 Index:0 DirStruct.Length:1
<file>f31.txt</file>
</directory>
Level:1 Index:1 DirStruct.Length:4
<directory>PATH:C:\trydir\d1\d21
Level:2 Index:0 DirStruct.Length:1
<file>f31.txt</file>
</directory>
Level:1 Index:2 DirStruct.Length:4
<directory>PATH:C:\trydir\d1\d21
</directory>
Level:0 Index:2 DirStruct.Length:1
<file>f31.txt</file>
Can some one please correct this code.

hi
here is the code i work for u
The code is changed and go through it
import java.io.*;
public class FetchDir2 {
    final static String path = "C:/web"; //path of user's workspace, change it accordingly
    public static void main(String s[]) {
        File fileTry = new File("c:/web");
        fetchStr(fileTry,0,0);
    public static void fetchStr(File fileTry,int level,int idx) {
        File dirList[]=fileTry.listFiles();
        sort(dirList);
        File f=null;
        System.out.println("Level:" + level+" Index:"+idx +" DirStruct.length:"+dirList.length);
        for(int i=0;i<dirList.length;i++){
            f = dirList;
System.out.println("Level:"+level+" Index:"+i );
if(f.isFile()){
System.out.println("<file>"+ f.getName()+"</file>");
else{
System.out.println("<directory> Path:"+fileTry.getPath());
fetchStr(f,level++,i);
System.out.println("</directory>");
public static void sort(File dirStruct[]) {
int compare=0;
for(int i=0;i<dirStruct.length-1;i++) {
for(int j=i+1;j<dirStruct.length;j++) {
compare= dirStruct[i].compareTo(dirStruct[j]);
if(compare>0)
swap(dirStruct[i],dirStruct[j]);
public static void swap(File f1,File f2) {
File f3;
f3=f1;
f1=f2;
f2=f3;
}Hopes it helps you...
