Create Multiple Files using Java

Submitted by donbermoy on Tuesday, May 13, 2014 - 22:54.
Today, I will teach you how to create different files using Java. Here, we will just use the io package. So, now let's start this tutorial! 1. Open JCreator or NetBeans and make a java program with a file name of CreateFiles.java. 2. Import java.io package. Hence we will use an input/output in creating files.
  1. import java.io.*;
3. In your main, initialize the following files and its file extension. - For word document
  1.  File file1 = new File("data.doc");
- For rich text file
  1.  File file1 = new File("data.rtf");
- For text file
  1.  File file1 = new File("data.txt");
- For excel file
  1.  File file1 = new File("data.xls");
- For access file
  1.  File file1 = new File("data.accdb");
4. Now, create a try and catch method. In your try method, do the following code. This will trigger to create files.
  1.   try
  2.         {            
  3.             FileWriter writer1 = new FileWriter(file1, true);
  4.             FileWriter writer2 = new FileWriter(file2, true);
  5.             FileWriter writer3 = new FileWriter(file3, true);
  6.             FileWriter writer4 = new FileWriter(file4, true);
  7.             FileWriter writer5 = new FileWriter(file5, true);
  8.      
  9.         }
In your Catch method, prefer to catch IOException then use printStackTrace() method. This will help to trace the exception and identify which method causes the bug.
  1. catch (IOException e)
  2.         {
  3.             e.printStackTrace();
  4.         }
Output: output Here's the full code of this tutorial:
  1. import java.io.*;
  2. public class CreateFiles
  3. {
  4.     public static void main(String[] args)
  5.     {
  6.                                 File file1 = new File("data.doc");
  7.                 File file2 = new File("data.rtf");
  8.                 File file3 = new File("data.txt");
  9.                 File file4 = new File("data.xls");
  10.                 File file5 = new File("data.accdb");
  11.         try
  12.         {            
  13.             FileWriter writer1 = new FileWriter(file1, true);
  14.             FileWriter writer2 = new FileWriter(file2, true);
  15.             FileWriter writer3 = new FileWriter(file3, true);
  16.             FileWriter writer4 = new FileWriter(file4, true);
  17.             FileWriter writer5 = new FileWriter(file5, true);
  18.      
  19.         } catch (IOException e)
  20.         {
  21.             e.printStackTrace();
  22.         }
  23.     }
  24. }
  25.
