1. 基本概念 Math对象的abs()方法用于计算一个数的绝对值，abs是单词"absolute"的缩写，而单词"absolute"有“绝对的”的意思。因此，求绝对值方法被命名为abs。Math.abs()方法的语法结构如下所示：Math.abs(x);其中参数x应该是一个数字，即x的类型应该是Number。如果x不是Number类型，那么它会先被强制类型转换...

但是字符串的hash值有可能是负数,所以我们需要使用Math.abs取分表键hash值的绝对值%100。这样看起来很好,但是还是会有问题。 因为字符串的hash值是int类型的,所以会取Math.abs(int a)作为取绝对值函数,当a为0x80000000时候,我们会看到其结果为:-2147483648,竟然为负数,然后如果对100取模,则会得到-48,根据-48...
