??? 本文本著學習分享的目的，介紹一種基于java.text.Collator的比較挫的方法，實現漢字轉換為拼音字符串。當然我得暫時不考慮漢字多音字的問題。最終結果是這樣：

??? 吃 -> CHI??? 睡 -> SHUI???? 做 -> ZUO

??? 需要直接拷貝代碼的請拉至貼末尾。

?

1，Unicode編碼

??? 古代秦國統一六國漢字，而Unicode編碼則統一了全世界文字。它整理了世界上大部分國家的文字，使得計算機可以簡單地顯示和處理它們。Unicode編碼方式有UTF-8, UTF-16, UTF-32 (Unicode Transformation Format). 為了表示0x10FFFF這么多個字符，UTF-8, UTF-16 對不同范圍的字符使用不同長度的編碼。具體怎么劃分編碼范圍，請自行網上搜索。這里只提起，漢字的編碼范圍是U+4E00 - U+9FFF。

Unicode字符百科 : http://unicode-table.com/cn/#4E00

?

2，java.text.Collator

??? Java 有別的一些比較和排序的類方法。Collator主要用來處理某種特定語言的比較和排序。比如我們這里的 中文。

??? 它提供四種等級的比較：

??? Primary :?基本等級，字典里面會按照基本字符進行排序。比如 "a"<"b"<"c"， "as"=="às"， "a"=="A"

??? Secondary : 第二等級，若基本等級比較結果相等，則根據語言考慮字符的聲調。比如 "as"<"às"， "a"=="A"

??? Tertiary :? 第三等級，若基本等級，第二等級比較結果相等，則根據字符的大小寫。比如 "a"<"A"

??? Identical : 骨灰級，若上面幾種對比均相等，則由這個等級決定雌雄。希伯來語Hebrew會用到這個等級。但是總的情況非常少，使用這個等級會降低代碼效率。

??? 在做比較之前，我們可以通過方法 setStrength( int ) 來設置比較等級：Collator.PRIMARY, Collator.SECONDARY, Collator.TERTIARY, Collator.IDENTICAL。

??? Collator類對漢字的排序，就是新華字典里面的排序。

?

3，漢字拼音

??? 因為有多音字，拼音與漢字是一種多對多的關系。不好搞。然而多音字其實占一個小部分而已，所以我們這里先忽略多音字的存在。現在關系明朗了許多：拼音漢字是1對多的關系了。翻看新華詞典，我們發現拼音數量是有限的。好了，那我們就通過查表來解決問題。我們的表是這樣的：

??? 表A: { 呵, 哎, 安, 骯, 凹, 八,?挀, ... }

??? 表B: { A, AI, AN, ANG, AO, BA, BAI, ...}

??? 好了，你應該看出來了。最卑鄙無恥的窮舉大法！列出所有拼音，以及拼音對應的第一個漢字。總共有407個拼音。其實說多也不多吧？

??? 接下來怎么辦呢？通過很賤的二分法查找，找到漢字的同音字！比如：

??? 我們要將"霸"字轉換為拼音。

??? Collator 取表A內容，比較結果："八" < "霸" < "挀"

??? 結果取表B內容，輸出 "BA"

???

4，思考

??? 在代碼里面定義兩個表(二維數組)開銷其實很少，另外，采用二分法查找，面對407個Item 最壞的情況也不會超過10次比較操作，我認為還是可取的。

??? 有人會問，那有沒有辦法把拼音轉換為漢字？首先，一個拼音對應的漢字非常多，這個問題的結果是一個集合。另外，實際情況我們似乎不需要這么搞。某個場合需要通過拼音找漢字，我們仍然可以先將漢字轉換為拼音，然后再做匹配。
