Java: Write to a file in UTF-32 Format

Question

Is it possible to write Strings to a file in utf-32 format? For example: the RandomAccessFile class only offers the writeUTF() Method, which writes the String in a modifed UTF-8 format.

Lets say my task is to write every existing unicode character into a file :).

Answer 1

You should convert your string to bytes in the UTF-32 format, and then write write those bytes to your random file

RandomAccessFile file = ...
String str = "Hi";
byte[] bytes = str.getBytes("UTF-32");
file.write(bytes);
