Method

intswap16(final int aValue)
Switches the order of bytes of the given (16-bit) word value. 
return (((aValue & 0x00ff) << 8) | ((aValue & 0xff00) >> 8));
shortswap16(short rgb)
swap 
int a = (rgb >> 8) & 0xFF;
int r = rgb & 0xff;
return (short) ((r << 8) | a);
intswap32(int rgb)
swap 
int a = (rgb >> 24) & 0xFF;
int r = (rgb >> 16) & 0xff;
int g = (rgb >> 8) & 0xff;
int b = rgb & 0xff;
return (b << 24) | (g << 16) | (r << 8) | a;
voidswapAddresses(T o1, T o2)
swap Addresses 
T temp = o2;
o2 = o1;
o1 = temp;
byteswapBits(byte in)
swap Bits 
return (byte) ((swapped_nybbles[in & 0xf] << 4) | (swapped_nybbles[(in & 0xf0) >> 4]));
intswapBits(int b, int i, int j)
swap Bits 
final int x = ((b >> i) ^ (b >> j)) & 1; 
return b ^ ((x << i) | (x << j));
intswapByte(byte b)
swap Byte 
int high = (0x0000000F & ((int) b));
high = high << 4;
int low = (int) b >> 4;
return high + low;
intswapBytes(final int i)
Swap bytes 
return (i << 24) | ((i << 8) & 0x00ff0000) | (i >>> 24) | ((i >> 8) & 0x0000ff00);
StringswapCasing(String str)
swap Casing 
int strLen;
if ((str == null) || ((strLen = str.length()) == 0)) {
    return str;
StringBuilder builder = new StringBuilder(strLen);
char ch = 0;
for (int i = 0; i < strLen; i++) {
    ch = str.charAt(i);
...
doubleswapDouble(double value)
Reverses the byte order of the source double value 
long l = Double.doubleToLongBits(value);
l = swapLong(l);
return Double.longBitsToDouble(l);
