StringUtils.lastOrdinalIndexOf介绍

[英]Finds the n-th last index within a String, handling null. This method uses String#lastIndexOf(String).

A null String will return -1.

StringUtils.lastOrdinalIndexOf(null, *, *)          = -1 
StringUtils.lastOrdinalIndexOf(*, null, *)          = -1 
StringUtils.lastOrdinalIndexOf("", "", *)           = 0 
StringUtils.lastOrdinalIndexOf("aabaabaa", "a", 1)  = 7 
StringUtils.lastOrdinalIndexOf("aabaabaa", "a", 2)  = 6 
StringUtils.lastOrdinalIndexOf("aabaabaa", "b", 1)  = 5 
StringUtils.lastOrdinalIndexOf("aabaabaa", "b", 2)  = 2 
StringUtils.lastOrdinalIndexOf("aabaabaa", "ab", 1) = 4 
StringUtils.lastOrdinalIndexOf("aabaabaa", "ab", 2) = 1 
StringUtils.lastOrdinalIndexOf("aabaabaa", "", 1)   = 8 
StringUtils.lastOrdinalIndexOf("aabaabaa", "", 2)   = 8

Note that 'tail(CharSequence str, int n)' may be implemented as:

str.substring(lastOrdinalIndexOf(str, "\n", n) + 1)

[中]查找字符串中最后第n个索引，处理null。此方法使用字符串#lastIndexOf（String）。
空字符串将返回-1。

StringUtils.lastOrdinalIndexOf(null, *, *)          = -1 
StringUtils.lastOrdinalIndexOf(*, null, *)          = -1 
StringUtils.lastOrdinalIndexOf("", "", *)           = 0 
StringUtils.lastOrdinalIndexOf("aabaabaa", "a", 1)  = 7 
StringUtils.lastOrdinalIndexOf("aabaabaa", "a", 2)  = 6 
StringUtils.lastOrdinalIndexOf("aabaabaa", "b", 1)  = 5 
StringUtils.lastOrdinalIndexOf("aabaabaa", "b", 2)  = 2 
StringUtils.lastOrdinalIndexOf("aabaabaa", "ab", 1) = 4 
StringUtils.lastOrdinalIndexOf("aabaabaa", "ab", 2) = 1 
StringUtils.lastOrdinalIndexOf("aabaabaa", "", 1)   = 8 
StringUtils.lastOrdinalIndexOf("aabaabaa", "", 2)   = 8

注意，“tail（CharSequence str，int n）”可以实现为：

str.substring(lastOrdinalIndexOf(str, "\n", n) + 1)
