Java UTF-8 file writing: Learn how to write files in UTF-8 encoding with Java

If you want to write files in UTF-8 encoding with Java, there are a few steps you need to follow. First, you need to create a new file and specify the encoding as UTF-8. You can do this by using the OutputStreamWriter class and passing in a FileOutputStream that points to the file you want to write to.

Once you have created the OutputStreamWriter, you can use it to write data to the file using the write() method. This method takes a string as input, which can be any valid UTF-8 encoded string.

Here's an example of how to write a string to a file in UTF-8 encoding using Java:


try {
  String data = "This is a sample string in UTF-8 encoding";
  OutputStreamWriter writer = new OutputStreamWriter(new FileOutputStream("myfile.txt"), "UTF-8");
  writer.write(data);
  writer.close();
} catch (IOException e) {
  e.printStackTrace();
}

In this example, we create a new OutputStreamWriter that writes to a file named "myfile.txt" and specifies the encoding as UTF-8. We then write a sample string to the file using the write() method.

It's important to note that when you read the file later, you'll also need to specify the encoding as UTF-8. You can do this by using a similar approach with an InputStreamReader.

In conclusion, writing files in UTF-8 encoding with Java is a simple process. Just make sure to specify the encoding when creating the OutputStreamWriter and use the write() method to write data to the file.
