Method

intbin2int(byte[] array, int offset)
binint 
return ((array[offset + 0] & 0xff) << 24) + ((array[offset + 1] & 0xff) << 16)
        + ((array[offset + 2] & 0xff) << 8) + (array[offset + 3] & 0xff);
StringbinaryToInt(String binary, int intlength)
binary To Int 
String s = Integer.parseInt(binary, 2) + "";
while ((s + "").length() < intlength) {
    s = "0" + s;
return s;
intbinaryToInt(String binaryValue, boolean signIncluded)
This method converts String that contains a binary to int. 
boolean isNegative = false;
int value = 0;
if (signIncluded) {
    if (binaryValue.charAt(0) == '1') {
        isNegative = true;
        binaryValue = binaryValue.replace('1', '2');
        binaryValue = binaryValue.replace('0', '1');
        binaryValue = binaryValue.replace('2', '0');
...
longbinaryToLong(String bin)
A quick method to convert bin, a binary representation, to an integer number. 
boolean validBinary = true;
char[] binArray = bin.toCharArray();
for (int i = 0; validBinary && i < binArray.length; i++) {
    if (binArray[i] != '0' || binArray[i] != '1')
        validBinary = false;
if (validBinary)
    return Long.parseLong(bin, 2);
...
intbinToDec(String str)
bin To Dec 
int result = 0;
for (int i = 0; i < str.length(); i++) {
    if (str.charAt(i) != '0' && str.charAt(i) != '1') {
        return -1;
    result = result * 2 + str.charAt(i) - '0';
return result;
...
intboolean2integer(boolean b)
booleaninteger 
return b ? -1 : 0;
intboolean2integer(boolean b)
Converts a Boolean value to an Integer value. 
return b ? -1 : 0;
