Description

The list of methods to do Hex String Create are organized into topic(s).

Method

voidappendHexNumber(StringBuffer target, byte b)
append Hex Number 
int lo = b & 0xf;
int hi = (b >> 4) & 0xf;
target.append(HEX[hi]);
target.append(HEX[lo]);
voidappendHexPair(byte b, StringBuffer sb)
append Hex Pair 
char c0 = hexDigits[(b & 0xf0) >> 4];
char c1 = hexDigits[b & 0x0f];
sb.append(c0);
sb.append(c1);
voidappendHexStream(StringBuilder sb, byte[] bytes, String delimiter, boolean prefixEachValue, boolean upperCase)
Same as #toHexStream(byte[],String,boolean,boolean) , but appends to an existing StringBuilder. 
sb.ensureCapacity(bytes.length * (prefixEachValue ? 4 : 2)
        + (bytes.length - 1) * (delimiter == null ? 0 : delimiter.length()));
for (int i = 0; i < bytes.length; i++) {
    if (prefixEachValue)
        sb.append("0x");
    char c1 = Character.forDigit((bytes[i] & 0xF0) >> 4, 16);
    char c2 = Character.forDigit((bytes[i] & 0x0F), 16);
    sb.append(upperCase ? Character.toUpperCase(c1) : c1);
...
voidappendHexString(StringBuffer buffer, byte data)
Append hex string from byte to StringBuffer 
int positive = data < 0 ? ~data : data;
buffer.append(HEX_DIGITS[positive >> 4]);
buffer.append(HEX_DIGITS[positive & 0xf]);
voidappendHexString(StringBuilder buffer, byte[] bytes)
Appends a byte array to a StringBuilder with each byte in a "Big Endian" hexidecimal format. 
assertNotNull(buffer);
if (bytes == null) {
    return; 
appendHexString(buffer, bytes, 0, bytes.length);
voidappendHexString(StringBuilder builder, int value)
append Hex String 
String hex = Integer.toHexString(value);
if (hex.length() == 1) {
    builder.append("0");
builder.append(hex);
voidappendHexValue(final StringBuffer sb, final byte data)
Convert a byte into hex value and add to buffer. 
sb.append(nibbleToHex((byte) (data >> 4)));
sb.append(nibbleToHex(data));
voidappendHexValue(StringBuffer buffer, byte b)
Helper method that converts a single byte to a hex string representation. 
int[] digits = { (b >>> 4) & 0x0F, b & 0x0F };
for (int d = 0; d < digits.length; ++d) {
    int increment = (int) ((digits[d] < 10) ? '0' : ('a' - 10));
    buffer.append((char) (digits[d] + increment));
