print directory tree

Question

I have to print a directory tree (like tree command), example:

 .
 +---A
 |   +---IMAGES
 |       +---BACKUP
 +---ADOKS
 |   +---ROZDZIAL_2
 |   +---ROZDZIAL         


        

Answer 1

import java.io.File;

public class MainEntry {
public static void main(String[] args) {
    walkin(new File("/home/user")); //Replace this with a suitable directory
}

/**
 * Recursive function to descend into the directory tree and find all the files 
  @param dir A file object defining the top directory
 **/
public static void walkin(File dir) {

    File listFile[] = dir.listFiles();
    if (listFile != null) {
        for (int i=0; i

}

Will work fine..The Logic is correct
