Hi Jones

Check this program code.I think it will help you.

import java.io.*;
 
public class Concatenate {
                     public static void concenateFile(String...fileName) {
                             String str = null;
                             try (BufferedWriter writer = new BufferedWriter(new FileWriter(
                                                "CombinedFile.txt"));)
{
                                      for(String name : fileName) {
                                                try(BufferedReader reader =                                                                          new
BufferedReader(new FileReader(
                                                                   name));)
{
                                                          while
((str = reader.readLine()) != null) {
                                                                   writer.write(str);
                                                                   writer.newLine();
                                                          }
                                                }
catch (IOException e) {
                                                          System.out.println("Error reading/writing file");
                                                }
                                      }
                             } catch (Exception
e) {
                                      e.printStackTrace();
                             }
                     }
 
                     public static void main(String[] args) {
                             if (args.length < 0) {
                                      System.out.println("Usage: java Concatenate file1 file2");
                                      System.exit(0);
                             }
                             concenateFile(args);
                             System.out.println("Successfully created CombinedFile.txt");
                     }
}
