Create a File and Write Data in Java Example

FileOutputStream is a class present in java.io package and child class of outputstream class. It Stores data in the form of bytes. It is used to create a text file.

In this program we are using BufferedReader class which is child class of Reader class is used to read data from keyboard.
BufferedReader file = new BufferedReader(new InputStreamReader(System.in));
Here file is the object of the FileOutputStream class that points to ” test txt file, if the file is not present it creates a new file.
FileoutputStream file=new FileoutputStream(“Hello.txt”);
ch=(char)br.read()
file.write(ch);
To close the file we have to close the associated streams.
file.close();

Here is the Java Example for Create a File and Write Data in Java:

import java.io.*; 
 class WriteDataFile 
 { 
            public static void main(String args[]) 
        { 
                 try 
              { 
                    BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); 
                    FileOutputStream file = new FileOutputStream("Hello.txt"); 
                    System.out.println("Enter text and Type 'y' to Terminate"); 
                    char c; 
                    while((c=(char)br.read())!='y') 
                    file.write(c); 
                   file.close(); 
                    System.out.println("File is Created"); 
              } 
                    catch(IOException e){} 
        } 
 }
