Returns the number of bits in the two's complement representation of this BigInteger that differ from its sign bit. This method is useful when implementing bit-vector style sets atop BigIntegers. Java documentation forjava.math.BigInteger.bitCount(). ...
java.lang 包的 Integer 类的 bitCount() 方法返回 int 值的二进制补码表示中一位数的计数。这个函数有时被称为人口计数。 语法: public static int bitCount(int n) Parameter : n : the value whose bits are to be counted Return : This method returns the count of the number of one-bits in the...
Java bitCount() method is a part of Long class which returns the one-bit number into two's complement binary form of the specified long value.

public static int bitCount(int n) Parameter : n : the value whose bits are to be counted Return : This method returns the count of the number of one-bits in the two's complement binary representation of an int value.示例:展示Java . lang . integer . bitcount()方法的工作。
Ps.This code could easily be extended to 64-bit integers, simply by changing the0x01010101to0x0101010101010101and the>> 24to>> 56. Indeed, the same method would even work for 128-bit integers; 256 bits would require adding one extra shift / add / mask step, however, since the number ...
options we discovered that the problem does not occur when using -XX:-UsePopCountInstruction. Which leads us to believe the problem is related to the use of the Long.bitCount method. If so, this could be a serious security bug, given the amount of bit shifting that goes on in encryption...
