bitwise right shift operator with example
What is a bit shift operator?
A bit shift operator is a low-level operator that works on the individual bits of an integer. It takes two operands. One is the integer whose bits we want to shift. The other represents the number of shifts. The result of a bit shift is a new integer. Bit-shift operators are easy to use and execute quickly on modern multicore CPU systems.
What are bitwise operators?
The Bitwise operators are used to perform operations a bit-level or to manipulate bits in different ways. The bitwise operations are found to be much faster and are some times used to improve the efficiency of a program. Basically, Bitwise operators can be applied to the integer types: long, int, short, char and byte.
How to use right shift operator in Java?
