按位“非”(~ ,也称为取补运 算,ones compliement operator )属于一元操作符;它只对一个操作数进行操作(其他位操 作是二元运算)。按位“非”生成与输入位相反的值——若输入 0,则输出 1;输入 1,则输 出 0。 位操作符和逻辑操作符都使用了同样的符号。因此,我们能方便地记住它们的含义:由于“位” 是非常“小”
Java bitwise operators give users a way to change individual bits. In this article, we take a look at how to use the operators using practical examples.
The following program, BitDemo, uses the bitwise AND operator to print the number "2" to standard output. class BitDemo { public static void main(String[] args) { int bitmask = 0x000F; int val = 0x2222; // prints "2" System.out.println(val & bitmask); } } «...
The user determines the variable values each time the program is run, using the INPUT statement, which prompts the user with the text enclosed within quotes. When the program is run, the screen would look as follows, with the operator's responses underlined: Sign in to download full-size ...

INT10-C Do not assume a positive remainder when using the % operator. INT12-C Do not make assumptions about the type of a plain int bit-field when used in an expression. INT13-C Use bitwise operators only on unsigned operands. INT14-C Avoid performing bitwise and arithmetic opera...
原文:https://beginnersbook.com/2019/07/java-program-to-calculate-compound-interest/ 在本教程中,我们将编写一个java 程序来计算复合利率。 复利计算公式 使用以下公式计算复利: P (1+ R/n) (nt) - P 这里P是本金额。 R是年利率。 t是投资或借入资金的时间。
The bitwise Or operator (|) produces a one in the output bit if either input bit is a one and product a zero only if both input bits are zero. The bitwise EXCLUSIVE OR or XOR (^), produces a one in the output bit if one or the other input bit is a one, but not both. ...
