Method

int toInt(boolean flag)
This method is equivalent to

flag ? 
return flag ? 1 : -1;

 int toInt(boolean value) 
Convert a boolean value to the appropriate int. 
return value ? 1 : 0;

 int toInt(boolean[] bits) 
to Int
int value = 0;
for (int i = 0; i < bits.length; i++) {
 boolean isSet = bits[i];
 if (isSet) {
 value += 1 << bits.length - i - 1;
return value;
...

 int toInt(byte b) 
to Int
return (int) b >= 0 ? b : (int) b + (int) Math.pow(2, 8);

 int toInt(byte b1, byte b2, byte b3, byte b4) 
to Int
return (b1 & 0xFF) | ((b2 & 0xFF) << 8) | ((b3 & 0xFF) << 16) | ((b4 & 0xFF) << 24);

 int toInt(byte byte0, byte byte1, byte byte2, byte byte3) 
Constructs int given four bytes. 
int b0 = byte3 << 24;
int b1 = (byte2 << 24) >>> 8;
int b2 = (byte1 << 24) >>> 16;
int b3 = (byte0 << 24) >>> 24;
return (b0 | b1 | b2 | b3);

int n = 0;
n ^= mostSignificant & 0xFF;
n <<= 8;
n ^= leastSignificant & 0xFF;
return n;
