File List shuffle

[killerwake]

greetings to this community.

i'm new on java and i'm trying to create a File List, and i used some scripts on google, but the problem is how i can shuffle the filelist????? here is the code:

package com.wowza.wms.example;

import java.io.File;

public class FolderTraversar {

private File fileObject;

public FolderTraversar(String fileObjectname)
{

fileObject = new File(fileObjectname);


}

public void traverse()
{
recursiveTraversal(fileObject);
}

public void recursiveTraversal(File fileObject){

if (fileObject.isDirectory()){
//System.out.println(indent + fileObject.getName());
File allFiles[] = fileObject.listFiles();
for(File aFile : allFiles){
recursiveTraversal(aFile);
}
}else if (fileObject.isFile()){
//System.out.println(indent + " " + fileObject.getName());
System.out.println(fileObject.getAbsoluteFile());
}
}

}

the problem is how i can shuffle the filelist?

What file list?

In the code you obtain an array allFiles of the children of the File currently being visited. Is this what you are trying to shuffle? If so, why?

-------------------------

When posting code use the code tags: you put [code] at the start of the code and [/code] at the end. That way the indenting is preserved and it is easier to read.

Use Arrays.asList() to obtain a list. Then use Collections.shuffle() on the list.

import java.util.Arrays;
import java.util.Collections;
import java.util.List;

public class ArrayShuffleEg {

    public static void main(String[] args) {
        String[] data = {"one", "two", "three", "four", "five"};
		
        List<String> list = Arrays.asList(data);
        Collections.shuffle(list);
		
        for(String str :list) {
            System.out.println(str);
        }
    }
}
