Bitwise operations in Java
Java bit operator
Bitwise operators are used to operate binary bits. Java provides bitwise operators as shown below:
Bitwise operator (>>,>>,&, |, ^ ,~ ), In the bitwise operator, ~ The others are binary operators. The
Bitwise operators allow us to manipulate a single "bit" in the primary data type of an integer, that is, bits. The bitwise operator performs a Boolean algebra on the corresponding bits in the two arguments and eventually produces a result.Bitwise
The bitwise operator is primarily for binary, and it includes: "and", "Non", "or", "XOR". On the surface it seems a bit like a logical operator, but the logical operator is a logical operation on two relational operators, while the bitwise operator

Bitwise OperatorsJava defines a number of bitwise operators that can be applied to integer types Long,int,short,char and byte.Bitwise operators are performed on BITS and perform bitwise operations. Suppose a = 60 and B =; now in binary format, they
Bitwise operators defined by Java performs operations on digits of the integer type directly. These integer types include long, Int, short, Char, and byte. Table 4-2 lists bitwise operations:Table 4.2-bit operators and their results
Operator result~
One, Java bit operation1. Presentation method:In the Java language, the binary number is represented by a complement, the highest bit is the sign bit, the sign bit for positive numbers is 0, and the negative is 1. The complement representation needs
Before you understand the displacement, look at the binary representations and relationships of positive and negative numbers:Example 15 and-15:15 The original code: 00000000 00000000 00000000 00001111Complement: 11111111 11111111 11111111 11110000+1
