逐个字符地翻译字符串 [英] Translating strings character by character

问题描述

我应该如何实现一种方法，该方法获取由拉丁字符组成的字符串，然后将其转换为由一组不同的字符组成的字符串，比如西里尔字母.

How should I go about implementing a method that gets a String composed of Latin characters to translate it into a String composed of a different set of characters, let's say Cyrillic.

例如，这是在PHP中完成的方式:

Here's how it's done in PHP for example:

function latin_to_cyrillic($string)
{
 $array = array(
  "а" => "a",
  "б" => "b",
  "в" => "v",
  "г" => "g",
  "д" => "d",
  "е" => "e",
  "ж" => "zh",
  "з" => "z",
  "и" => "i",
  "й" => "y",
  "к" => "k",
  "л" => "l",
  "м" => "m",
  "н" => "n",
  "о" => "o",
  "п" => "p",
  "р" => "r",
  "с" => "s",
  "т" => "t",
  "у" => "u",
  "ф" => "f",
  "х" => "h",
  "ц" => "ts",
  "ч" => "ch",
  "ш" => "sh",
  "щ" => "sht",
  "ь" => "y",
  "ъ" => "a",
  "ю" => "yu",
  "я" => "ya",
  "А" => "A",
  "Б" => "B",
  "В" => "V",
  "Г" => "G",
  "Д" => "D",
  "Е" => "E",
  "Ж" => "Zh",
  "З" => "Z",
  "И" => "I",
  "Й" => "Y",
  "К" => "K",
  "Л" => "L",
  "М" => "M",
  "Н" => "N",
  "О" => "O",
  "П" => "P",
  "Р" => "R",
  "С" => "S",
  "Т" => "T",
  "У" => "U",
  "Ф" => "F",
  "Х" => "H",
  "Ц" => "Ts",
  "Ч" => "Ch",
  "Ш" => "Sh",
  "Щ" => "Sht",
  "Ь" => "Y",
  "Ъ" => "A",
  "Ю" => "Yu",
  "Я" => "Ya",
  "–" => "-");

 return str_replace(array_values($array), array_keys($array), $string);

}

推荐答案

首先，您需要一个转换表，为每个字符定义转换.

First of all you need a conversion table, defining the translation for every character.

然后，您按char读取字符串char，并使用翻译表获取翻译.容易吧?

Then you read the string char by char, and use the translation table to get the translation. Easy, right?

您可以使用以下内容:

class Translator {
 HashMap<String,String> translation = new HashMap<String,String>();

 public Translator(){
  //Populate the translation table here;
 }

 public String translate(String origin){
  String destiny="";
  for(int i=0;i<origin.length();i++){
   char character = origin.charAt(i);
   destiny = destiny + translation.get(Character.toString(character));
  }
 return destiny;
 }
}

或者，您可以使用

replaceEach(String text, String[] searchList, String[] replacementList) 
           Replaces all occurrences of Strings within another String.

来自 org.apache.commons.lang.StringUtils .您可以用拉丁字符(但以 String )填充 String [] ，然后用西里尔字母填充其他 String [] 为 String ，然后使用该函数.

From org.apache.commons.lang.StringUtils . You could populate a String[] with the latin characters (but as String), then populate another String[] with the cyrillic characters as String, and use that function.

String[] latinCharacters = [] //Populate them
String[] cyrillicCharacters = [] //Populate them

public String translate(String origin){
return replaceEach(origin,latinCharacters,cyrillicCharacters);
}
