The Java programming language also provides operators that perform bitwise and bit shift operations on integral types. The operators discussed in this section are less commonly used. Therefore, their coverage is brief; the intent is to simply make you aware that these operators exist. The unary ...

However, almost all programming languages (C, C++, Java) lack native operators or built-in functions for circular shifting. 3. Left Shift In this section, we focus on the non-circular left shift operator (<<). It shifts the first operand to the left by the number of bits specified by ...
