File.createNewFile() Method can be used to Atomically creates a new, empty file named by this abstract pathname if and only if a file with this name does not yet exist. File.createNewFile() Method returns true if the named file does not exist and was successfully created; false if the named file already exists.
Below is the example to create a file in java.
//package com.codebind.file; import java.io.File; import java.io.IOException; public class CreateFileClass { public static void main( String[] args ) { try { File file = new File("C:\\fileName.txt"); if (file.createNewFile()){ System.out.println("New File is created!"); }else{ System.out.println("File with the same name already exists."); } } catch (IOException e) { e.printStackTrace(); } } }
Java Examples – Create a File and Write in it Using PrintWriter and File class
import java.io.File; import java.io.IOException; import java.io.PrintWriter; public class Demo { public static void main(String[] args) { try { File file = new File("fileName1.txt"); if(!file.exists()) { file.createNewFile(); } PrintWriter pw = new PrintWriter(file); pw.println("this is my file content"); pw.println(100000); pw.close(); System.out.println("Done"); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
