Java File example to create an empty file using createNewFile
public boolean createNewFile()
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.
Program:
package com.candidjava;
import java.io.*;
public class FileCreateNewFile
{
public static void main(String[] args)
{
File f = null;
boolean bool = false;
try
{
f = new File("mmn.txt");
bool = f.createNewFile();
System.out.println("The File Created:" + bool);
bool = f.createNewFile();
System.out.println("The File Created:" + bool);
}
catch (Exception e)
{
System.out.println(e);
}
}
}
Output:
The File Created:true
The File Created:false
Description:
An empty file is created and returns a boolean.
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
