Detailed explanation of java displacement operator
Java bit shift operators are operators that operate on binary numbers. They shift the bits of a binary number to the left or right by a specified number of bits, and then fill in the zero bits or sign bits. There are three bit shift operators: left shift operator (<<), right shift operator (>>), and unsigned right shift operator (>>>). For more information about Java's displacement operators, you can visit the articles below this topic.
Detailed introduction to java bit shift operatorJava bit shift operators are operators that operate on binary numbers. They shift the bits of a binary number to the left or right by a specified number of bits, and then fill in the zero bits or sign bits. There are three bit shift operators: left shift operator (<<), right shift operator (>>), and unsigned right shift operator (>>>).
How to calculate left shift operator in javaCalculation method: 1. Convert the binary number to be moved into binary format; 2. Move the binary number to the left by the specified number of digits, and fill in zero bits on the right side after the movement. For example, shift the binary number 1010 to the left by 2 bits to obtain 00101000; 3. Convert the shifted binary number to a decimal number, which is the calculation result of the left shift operator. For example, converting 00101000 to decimal gives 40.
How to use java right shift operatorJava right shift operator usage: 1. Signed right shift, moves a binary number to the right by the specified number of digits, and fills the digits on the left according to the sign bit of the original number. If the original number is a positive number, it is on the left Fill zero bits, if the original number is a negative number, fill one 1 on the left; 2. Unsigned right shift, move a binary number to the right by the specified number of digits, and fill zero bits on the left, regardless of the original number sign bit.
How to use unsigned right shift in javaThe usage of unsigned right shift in Java is to move a binary number to the right by the specified number of bits and fill it with zero bits on the left, regardless of the sign bit of the original number. The syntax of the unsigned right shift operator is "int result = value >>> num;", where value is the binary number to be moved, num is the number of digits to be moved, and result is the operation result.
