How to Create File using Java

Following example shows hoe to create file using File() constructor and file.createNewFile() method in Java

createNewFile
public boolean createNewFile() throws
Atomically creates a new, empty file named by this abstract pathname if
and only if a file with this name does not yet exist. The check for the existence of the file and the creation of the file if it does not exist are a single operation that is atomic with respect to all other filesystem activities that might affect the file.

Note: this method should not be used for file-locking, as the resulting protocol cannot be made to work reliably. The FileLock facility should be used instead.
Returns:
true if the named file does not exist and was successfully created; false if the named file already exists.
Throws:
IOException - If an I/O error occurred.
SecurityException - If a security manager exists and its SecurityManager.checkWrite(java.lang.String) method denies write access to the file.

Sample Program
CreateFile.java

package com.javatutorialcorner.file;

import java.io.File;
import java.io.IOException;

public class CreateFile {

 public static void main(String[] args) {
  String path = "/home/annamalai/workspace/File/jtc.txt";
  try {
   File jtcFile = new File(path);
   if (!jtcFile.exists()) {
    jtcFile.createNewFile();
    System.out.println("File Created Successfully!");
   } else {
    System.out.println("Error, file already exists.");
   }
  } catch (IOException ioe) {
   ioe.printStackTrace();
  }

 }

}

Result
The above code will create new file if file not exist in specified directory.

File Created Successfully!
