Java help very appreciated, how do you tell how many bytes are written to a file given the data stream, does it change with a buffered input stream, and how many bytes does each character take up, as well as other variables including ints, and strings.

Thanks for the help!

After running this program, how many bytes are there in t.dat? import java.io. public class Ex4 { public static void main(String[] args) try (DataOutputstream output - new DataoutputStream new Fileoutputstream("t.dat"));) l output.writeChar('A) output.writeUTF("DEF"); catch (Exception e))
