I want to print on which level the file is present in given directory structure when using recursion

[Chaitanya Tedla]

Hi,

I want to print on which level file is present in a given root directory A:

for example::

A is my root directory..

I have subdirectories B and C in that..

And again in B i have D and E directories...

In D,i have files f1,f2

In E,i have files f3,f4..

In C also assume i have some directories..

Now i want to print for each file in which level that is present given a root directory...

Can anyone help me..

My program::

package com.ibm;

import java.io.File;

/**

 */
public class FileListing {
    
public static void main(String args[])
{
File driveRoot = new File("C:\\Users\\chaitu\\Desktop\\a");


FileLister fl = new FileLister();
fl.listFilesInDirectory(driveRoot);

}
}

class FileLister
{
public void listFilesInDirectory(File dir)
{
   System.out.println("this method listfiles called");
    File files[] = dir.listFiles();
    int fileLevel = 0;
    int count=0;
    if(files != null)
    {
        for(File f : files)
        {
           // boolean b = true;
            //boolean c=true;
            System.out.println("Entered into the File for loop"+ f.getAbsolutePath());
            
           
            if(f.isDirectory())
            {               
                listFilesInDirectory(f);                 
                //fileLevel++;
                
                //b = false;
                
                
              
             }
            else
            {   //c = false;
                System.out.println(f.getAbsolutePath());
                //System.out.println("The level in which the file was present" + fileLevel);
                //if(b==false && c == true)
                    //fileLevel--;
                            
            }
            
        }
    }
        
}

}

Chaitanya,
Welcome to CodeRanch! I added code tags to make your post easier to read. You are pretty close using recursion. Think about the method signature - public void listFilesInDirectory(File dir) .

Suppose it had an extra parameter to keep track of the level. What would you pass in the first time you call it? What would you do to that value when you were one more level down?

Thanks for the help!!
I got that!!
