Write a file in UTF-8 using FileWriter (Java)?

Write a file in UTF-8 using FileWriter (Java)?

To write a file in UTF-8 encoding using FileWriter in Java, you can use OutputStreamWriter along with FileOutputStream to specify the character encoding. Here's how you can do it:

import java.io.*; public class Main { public static void main(String[] args) { try { // Specify the file path String filePath = "output.txt"; // Create an OutputStreamWriter with UTF-8 encoding Writer writer = new OutputStreamWriter(new FileOutputStream(filePath), "UTF-8"); // Write some text to the file writer.write("Hello, world! 你好, 世界!"); // Close the writer writer.close(); System.out.println("File written successfully."); } catch (IOException e) { e.printStackTrace(); } } }

In this example:

  • We specify the file path where we want to write the file.
  • We create an OutputStreamWriter and wrap it around a FileOutputStream to specify UTF-8 encoding.
  • We write some text to the file using the writer.
  • Finally, we close the writer.

This will create a file named "output.txt" in the current directory with the text "Hello, world! 你好, 世界!" encoded in UTF-8. Make sure to handle IOExceptions appropriately in your production code.

Examples
