Program to Create File in current path using new File(currentPath, fileName), File.separator or System.getProperty("file.separator") in java file IO


Must read : Create File using createNewFile() method in java file IO

Find current directory or current path in java



In this post we'll create file in current path (or working path or current directory) using

1) new File(currentPath, fileName);
2) System.getProperty("file.separator") or
File.separator



Program 1 to Create File in current path using new File(currentPath, fileName), File.separator in java file IO

import java.io.File;
import java.io.IOException;
/** JavaMadeSoEasy.com */
public class CreateFileInCurrentDirectory {
   public static void main(String[] args) {
    try {
          String fileName = "myFile.txt";
         
          String currentPath = System.getProperty("user.dir");
          System.out.println("currentPath = "+ currentPath);
          //Now, let's create file using new File(currentPath, fileName) method
          File file = new File(currentPath, fileName);
          if (file.createNewFile())
                 System.out.println("File has been created successfully > "
                              + (currentPath + File.separator + fileName));
          else
                 System.out.println("File with the given name already exists > "
                              + (currentPath + File.separator + fileName));
    } catch (IOException e) {
          e.printStackTrace();
    }
   }
}
/*OUTPUT
currentPath = E:\workspace\FileHandling
File has been created successfully > E:\workspace\FileHandling\myFile.txt
*/


Program 2  to Create File in current path using System.getProperty("file.separator") in java file IO

import java.io.File;
import java.io.IOException;
/** JavaMadeSoEasy.com */
public class CreateFileInCurrentDirectory {
   public static void main(String[] args) {
    try {
          String fileName = "myFile.txt";
         
          String currentPath = System.getProperty("user.dir");
          System.out.println("currentPath = "+ currentPath);
         
          String absoluteFilePath = new String( currentPath + File.separator + fileName);
          System.out.println("File will be created in (absoluteFilePath)> "+
                     absoluteFilePath);
         
          //Now, let's create file in absoluteFilePath
          File file = new File(absoluteFilePath);
          if (file.createNewFile())
                 System.out.println("File has been created successfully > "
                        + absoluteFilePath);
          else
                 System.out.println("File with the given name already exists > "
                        + absoluteFilePath);
    } catch (IOException e) {
          e.printStackTrace();
    }
   }
}
/*OUTPUT
currentPath = E:\workspace\FileHandling
File will be created in (absoluteFilePath) > E:\workspace\FileHandling\myFile.txt
File has been created successfully > E:\workspace\FileHandling\myFile.txt
*/

In above program, we may use any of the following  >
System.getProperty("file.separator") or
File.separator
