什么是Java相当于.NET的IEquatable接口？

What is the Java equivalent of .NET's IEquatable Interface?

推荐答案

不幸的是，我不相信有一个 - 这是在提供哈希映射等定制的相等比较而言痛苦：（

Unfortunately I don't believe there is one - which is a pain in terms of providing hash maps etc with custom equality comparisons :(

显然有可比＆LT; T＆GT; 作为等同于 IComparable的＆LT; T＆GT; 和比较＆LT; T＆GT; 为的IComparer＆LT; T＆GT; ，但我不相信有任何相等于的IEqualityComparer＆LT; T＆GT; 和 IEquatable＆LT; T＆GT;

Obviously there's Comparable<T> as an equivalent to IComparable<T> and Comparator<T> for IComparer<T>, but I don't believe there's any equivalent of IEqualityComparer<T> and IEquatable<T>.

有可能是第三方库提供相同的排序界面和地图的哪些使用，当然他们......

There may be third party libraries providing the same sort of interface and maps which use them of course...
