It is tempting to use bit operation for this problem. However, bit shift operator works on integer, not knowing the internal byte order, and that property prevents us from using the bit operators to determine byte order. To check out the endian, we can just print out an integer (4 byte)...
Languages handle arithmetic and logical right shifting in different ways. Java provides two right shift operators: >> does an arithmetic right shift and >>> does a logical right shift. 1011 >> 1 → 1101 1011 >> 3 → 1111 0011 >> 1 → 0001 0011 >> 2 → 0000 The first two numbers...
Bit Twiddling was used in earlier days for efficiency. It is a technique used for bit manipulation. Java bitwise and bit shift operators such as NOT, AND, OR, XOR, LEFT-SHIFT, RIGHT-SHIFT, UNSIGNED-RIGHT-SHIFT can be used to perform operations such as multiply or divide integers, test fo...
