UTF-16 is a character encoding scheme that represents each Unicode character with either one or two 16-bit code units. Java provides built-in support for UTF-16 encoding through its java.nio.charset package. In this blog post, we will explore how to write text in UTF-16 encoding using Java.

Writing Text in UTF-16

To write text in UTF-16 encoding in Java, you need to take the following steps:

1. Create a byte stream that represents the desired output location, such as a file or an output stream.
2. Wrap the byte stream with a OutputStreamWriter to convert the bytes to characters using the UTF-16 encoding.
3. Use the write() method of the OutputStreamWriter to write the desired text.

Here is an example of writing a UTF-16 encoded text to a file in Java:

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.nio.charset.StandardCharsets;

public class Utf16WriterExample {
    public static void main(String[] args) {
        String textToWrite = "Hello, World! 你好，世界!";
        String outputFile = "output.txt";

        try (OutputStream outputStream = new FileOutputStream(outputFile);
             OutputStreamWriter writer = new OutputStreamWriter(outputStream, StandardCharsets.UTF_16)) {
            writer.write(textToWrite);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

In this example, we create a FileOutputStream to represent the output file, and then wrap it with an OutputStreamWriter that uses UTF-16 encoding. We then use the write() method to write the desired text.

Conclusion

In this blog post, we learned how to write text in UTF-16 encoding using Java. By following the provided steps and using the appropriate classes from the java.nio.charset package, you can easily write Unicode text in UTF-16 encoding in your Java applications.
