Writing a Text File in Java with Source Code

This Writing a Text File in Java tutorial will show you how to create txtFile. A text file has the.txt extension.

The libraries BufferedWriter, FileWriter, IOException, and Scanner are used in this lesson.

The produced file is located inside your Netbeans project after the application finishes writing it.

This article has a zip file and you can download it for free.

What is the use of Writing To a Text File in Java?

Many application programs are built to process data from and write to text files.

Any type of file can be handled by a Java program (since fundamentally all files are collections of bytes and Java can certainly read bytes.)

Reading, writing, editing, and other functions on a file are examples of file handling.

Without having to open the file, Java allows us to do these operations through code.

Advantages of Creating and Writing Text Files in Java?

The mobility of text files is a significant benefit. The representation used in binary files differs from computer to computer. Platform independence is a feature of Java binary files. Any computer that supports Java may interpret them.

Example Code

package writefile;

import java.io.FileWriter;

public class WriteFile {

    public static void main(String[] args) {
        try {
            FileWriter fw = new FileWriter("D:\\testout.txt");
            fw.write("Welcome to sourcecodehero.com.");
            fw.close();
        } catch (Exception e) {
            System.out.println(e);
        }
        System.out.println("Success...");
    }
}

Different Ways of Writing a Text File In NetBeans?

Different Ways of Writing a Text File

1. BufferedWritter.
2. FileWriter — Directly writes to the file.
3. Write prepared text with PrintWriter.
4. Write binary data to the FileOutputStream.
5. Write primitive data types with DataOutputStream.
6. Write bigger files with FileChannel.
7. Using Java 7 Path, create a file.

About the Project

The Netbeans project is normally found in your Documents folder. Please complete this instruction by following all of the steps.

Text files are written and read using the FileWriter and FileReader classes (they are Character Stream classes). If you need to read or write text, you should avoid using the FileInputStream and FileOutputStream classes because they are Byte stream classes.
