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
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
One of the most basic uses of computers is to perform mathematical operations, and as a computer language, Java also provides a rich set of operators to manipulate variables. We can divide the operators into the following groups:
Arithmetic
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

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
