Bit operations on unsigned values.

Question

// I have a byte array of length 4:
byte[]ba = {0xff, 0x00, 0xf0, (byte)0x0f};
// the, i have an int,
int iResult;
// and I want to copy the content of the bytes bitwise into the integer:
if(iResult == 0xff00f00f)
  // I become happy
else
  // I become frustrated.

Answer 1

One way is:
int num=new BigInteger(ba).intValue();
If you search the forums, you should be able to find code that does the same thing using a loop and bit shifting. The loop is probably faster, if that is critical to your code.
