然后11001000的最高位是1,那么表示是一个负数,而负数在计算机中都是以补码的形式保存的,所以我们计算11001000的原码为00111000,即56,所以11001000表示的是-56,所以最后test的值为-56。 java中各数据类型的取值范围: 1、int。 最小值:Integer.MIN_VALUE= -2147483648 (-2的31次方) 最大值:Integer.MAX_VALUE= 2147483647 (2的31次方-1) 2、long。 最小值:Long.MIN...
Bitwise operators are most commonly used for testing and setting individual bits in a value. If either of the arguments to a bitwise operator is a long, the result is a long. Otherwise, the result is an int. Java's bitwise operators are ~ ("bitwise complement or not operator"), & ("...
setting or shifting individual bits in a value. In order to work with these operators, one should be aware of the binary numbers and two’s complement format used to represent negative integers.
In Bitwise operations: Binary values are stored in two's complement. The tools work on 32-bit integers. The leftmost bit position is reserved for the sign of the value (positive or negative). If the integer is positive, the bit position is 0; if it's negative, the bit position is 1...
Let’s do the complement of value1 = 6: @Test public void givenOneInteger_whenNotOperator_thenNewDecimalNumber() { int value1 = 6; int result = ~value1; assertEquals(-7, result); } The value in binary is: value1 = 0000 0110 By applying the complement operator, the result will be...
The operators discussed in this section are less commonly used. Therefore, their coverage is brief; the intent is to simply make you aware that these operators exist. The unary bitwise complement operator "~" inverts a bit pattern; it can be applied to any of the integral types, making ...
Byte type is one of the important typesin Java. It is 8 bit long and is a signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). The byte data type are often used in low level data processing ( could be audio data processing etc)...
bitwise complement of N = ~N (represented in 2's complement form) 2'complement of ~N= -(~(~N)+1) = -(N+1) Example 4: Bitwise complement #include <stdio.h> int main() { printf("Output = %d\n", ~35); printf("Output = %d\n", ~-12); return 0; } Run Code Output ...
以下是《Thinking in java》中的描述: The bitwise NOT (~, also called the ones complement operator) is a unary operator; it takes only one argument. (All other bitwise operators are binary operators.) 非运算符是一个一元运算符,它只需要一个参数。(其它的位运算符都是二元运算符) ...
