Description

The list of methods to do Char Array to Byte Array are organized into topic(s).

Method

byte[]charsToBytes(char[] in)
Note: only one-byte symbols are supported. 
int size = in.length;
byte[] out = new byte[size];
for (int i = 0; i < size; i++) {
    out[i] = (in[i] < 256) ? (byte) in[i] : 63 ;
return out;
voidcharsToBytes(final char[] chars, final int charOffset, final int length, final byte[] bytes, final int byteOffset)
Convert chars to bytes merely by casting 
for (int i = 0; i < length; ++i) {
    bytes[byteOffset + i] = (byte) chars[charOffset + i];
byte[]ConvertCharArrayToByteArray(char value[])
Converts a char array into a byte array by typecasting each char to a byte 
byte returnValue[] = new byte[value.length];
int count = 0;
while (count < value.length) {
    returnValue[count] = (byte) value[count];
    count++;
return returnValue;
byte[]convertCharsToBytes(char[] chars)
Converts an array of unsigned 16bit numbers to an array of bytes. 
byte[] result = new byte[chars.length * 2];
for (int i = 0; i < chars.length; i++) {
    result[2 * i] = (byte) (chars[i] / 256);
    result[2 * i + 1] = (byte) (chars[i] % 256);
return result;
byte[]convertCharsToBytes(char[] chars)
convert Chars To Bytes 
byte[] result = new byte[chars.length * 2];
for (int i = 0; i < chars.length; ++i) {
    result[2 * i] = (byte) (chars[i] / 256);
    result[2 * i + 1] = (byte) (chars[i] % 256);
return result;
