java - Java 中的音译。重新定义字符串中的每个字符

Question

方法的目的是字符串的音译，例如:афиваў => afivaw。问题是:我无法使用 charAt 方法重新定义，因为有一些字母需要音译为两个符号 'ш' => "sh"。我试试这个:

public static String belrusToEngTranlit (String text){
    char[] abcCyr = {'a','б','в','г','д','ё','ж','з','и','к','л','м','н','п','р','с','т','у','ў','ф','х','ц','ш','щ','ы','э','ю','я'};
    String[] abcLat = {"a","b","v","g","d","jo","zh","z","i","k","l","m","n","p","r","s","t","u","w","f","h","ts","sh","sch","","e","ju","ja"};
    for (int i = 0; i < text.length(); i++) {
        for(int x = 0; x < abcCyr.length; x++ )
        if (text.charAt(i) == abcCyr[x]) {
            text.charAt(i) = abcLat[x];
        }
    }
    return text;
}

也许你可以推荐我一些除了 charAt 之外的东西？

字符串是不可变的，因此您无法更改其中的任何文本。所以你可以使用StringBuilder来存储结果。请参阅下面的代码。

public static String belrusToEngTranlit (String text){
    char[] abcCyr = {'a','б','в','г','д','ё','ж','з','и','к','л','м','н','п','р','с','т','у','ў','ф','х','ц','ш','щ','ы','э','ю','я'};
    String[] abcLat = {"a","b","v","g","d","jo","zh","z","i","k","l","m","n","p","r","s","t","u","w","f","h","ts","sh","sch","","e","ju","ja"};

    StringBuilder builder = new StringBuilder();

    for (int i = 0; i < text.length(); i++) {
        for(int x = 0; x < abcCyr.length; x++ )
        if (text.charAt(i) == abcCyr[x]) {
            builder.append(abcLat[x]);
        }
    }
    return builder.toString();
}
