The createFile() method is also used to create a new, empty file. The File.createFile() is a method of File class which belongs to package. String str=sc.nextLine()+"\n" //str stores the string which we have enteredīyte b= str.getBytes() //converts string into bytes String name=sc.nextLine() //variable name to store the file nameįileOutputStream fos=new FileOutputStream(name, true) // true for append mode Scanner sc=new Scanner(System.in) //object of Scanner class The FileOutputStream class provides a constructor to create a file.
