UTF_16BE_Writer

public class UTF_16BE_Writer extends com.sun.cldc.i18n.StreamWriter
The class encodes char array into byte stream in big-endian format. Each char requires two bytes to encode it. Note: The Unicode standard allows for characters whose representation requires more than 16 bit. Characters whose code points are greater than U+FFFF are called supplementary characters. Since String represents a string in the UTF-16 format in which supplementary characters are represented by surrogate pairs, so a supplementary character uses two positions in a String. Therefore, UTF_16BE_Writer doesn't care about supplementary characters, it treats them as usual characters.

return
number of bytes that would be occupied

	return length*2;
public voidwrite(char[] cbuf, int off, int len)
Write a portion of an array of characters.

param
cbuf Array of characters
param
off Offset from which to start writing characters
param
len Number of characters to write
exception
IOException If an I/O error occurs

	
	final int outputSize = 2; // Always write 2 encoded bytes
	byte[] outputByte = new byte[outputSize];
	char   inputChar;
        int    count = 0;

	while (count < len) {
	    inputChar = cbuf[off + count];
	    outputByte[0] = (byte)((inputChar >> 8) & 0xff);
	    outputByte[1] = (byte)(inputChar & 0xff);
	    out.write(outputByte, 0, outputSize);
