/ ** Swap The Upper and Lower Bytes of A Two Byte Integer.
THIS USEFUL WHEN You NEED TO Convert Between Intel formatted Integers (Little Endian) and Java / Motorola Formatted Integers (BIG Endian).
@Param x The number to be converted.
@Return the conveilted number.

this is useful when you need to convert Between Intel formatted integers (Little Endian) and Java / Motorola Formatted Integers (BIG Endian).
IF The Original Hex Number Was Abcd, The New Hex Number Will Be DCBA.
@Param x The number to be converted.
@ / public static int endian (int x) {int a = x >>> 24; int b = (x >>> 16 ) & 0xff; INT C = (x >>> 8) & 0xff; int D = x & 0xff; x = (D << 24) | (c << 16) | (B << 8) | a; Return x;} / ** Convert a Possibly Negative Valued Byte to A Positive Value Integer.
A Java byte has a value of -128 to 127. With eight bits and no sign, the negative numbers could be represented as a value of 128 to 255. This method makes such a conversion, but stores the result in an integer since Java does Not support unsigned bytes.
@Param B The byte with a possibly negative value.
@return an integer with a value of 0 to 255.
* / public static int referenceopositiveint (byte b) {INT i = B; IF (i <0 ) {I = 256;} return i;}

This Method Assumes Your Integer Will Be of the Range of 0 To 255. Using a value Outside of this Range Could Generate An Exception.
@Param I The Integer in The Range of 0 To 255.
@Return a byte with a Possibly Negative Value.
