通过前面这个例子,大概可以知道,先通过hashcode来比较,如果hashcode相等,那么就用equals方法来比较两个对象是否相等,用个例子说明:上面说的hash表中的8个位置,就好比8个桶,每个桶里能装很多的对象,对象A通过hash函数算法得到将它放到1号桶中,当然肯定有别的对象也会放到1号桶中,如果对象B也通过算法分到了1号桶,那...
Normally, most Java objects provide a built-in equals() and hashCode() based on the object's identity; so each new() object will be different from all others. This is generally what you want in ordinary Java programming. And if all your objects are in memory, this is a fine model. H...
If they are not equal in terms of equals() then they might or might not return the same hashCode() - if the hashCode() is well written then the chance of non-equal objects returning the same hashCode() should be low, but doesn't have to be zero. Also, if at all possible, an ...
当两个对象的hashcode不同的话,肯定他们不能equal. 两个对象相等必须满足: hashcode相等(Hash表中的同一个key上)>>equals()返回true(这个key上的链表上的同一位置) 1、如果两个对象相等,那么它们的hashCode值一定要相等; 2、如果两个对象的hashCode相等,它们并不一定相等。 改写equals时总是要改写hashCode : impo...
