How to get the list of Files inthe Directory and write data into them One by One

Hi Forum,

I have 100 text files, I need to write data into them. I am reading data from another file.

Please provide me some guideline for doing this...

Thanks in Advance...

Anything tried yet? Or nothing attempted? :(nerd):

HI

Code:

---

import java.io.*;
import java.io.Writer;

public class CreateFile2{
    public static void main(String[] args) throws IOException{
      File f;
         
 try{
    String strDirectoy ="test";
    String strManyDirectories="Application\\Test\\";

    // Create directory
      boolean  success = (new File(strManyDirectories)).mkdirs();

    if (success) {
      System.out.println("Directories: " + strManyDirectories + " created");


for (int i=0;i<=100 ;i++)
          { 
                                 
                  f=new File( ""+ strManyDirectories +""+"Application"+i+".txt");
        f.createNewFile();

        FileWriter fstream = new FileWriter(f,true);
        BufferedWriter out = new BufferedWriter(fstream);
        out.write("Hello Java");
        out.close();

          }
               
    }
      }catch (Exception e){//Catch exception if any
      System.err.println("Error: " + e.getMessage());
    }         

        }

Above Code will create the file from application0.txt to the end of loop.
I need to write data into them
bye selecting files one by one

Sorry for my English...

Don't do your operation on the basis of,

Code:

---

if (success) {

---

Instead, create the directory and check if it exists. Something like,

Code:

---

File dir = new File(strManyDirectories);
dir.mkdirs();

if(dir.exists()){ ....//Rest of the code.

---

Currently your code isn't getting passed through the if statement because when the directory exists it doesn't create it second time and returns false.

Hope that helps,
