Java替换德国变音符 [英] java replace German umlauts

问题描述

我有以下问题.我正在尝试替换Java中的ä，ö，ü的德语变音符号.但这根本行不通.这是我的代码:

I have the following problem. I am trying to replace german umlauts like ä, ö, ü in java. But it simply does not work. Here is my code:

private static String[][] UMLAUT_REPLACEMENTS = { { "Ä", "Ae" }, { "Ü", "Ue" }, { "Ö", "Oe" }, { "ä", "ae" }, { "ü", "ue" }, { "ö", "oe" }, { "ß", "ss" } };
public static String replaceUmlaute(String orig) {
    String result = orig;

    for (int i = 0; i < UMLAUT_REPLACEMENTS.length; i++) {
        result = result.replaceAll(UMLAUT_REPLACEMENTS[i][0], UMLAUT_REPLACEMENTS[i][1]);
    }

    return result;
}

ä仍然是ä，依此类推.我不知道此问题是否与编码有关，但字符串包含我要替换的确切字符.

An ä remains an ä and so on. I do not know if this issue has something to do with encoding, but the String contains the exact character I am trying to replace.

提前谢谢

推荐答案

这终于对我有用:

private static String[][] UMLAUT_REPLACEMENTS = { { new String("Ä"), "Ae" }, { new String("Ü"), "Ue" }, { new String("Ö"), "Oe" }, { new String("ä"), "ae" }, { new String("ü"), "ue" }, { new String("ö"), "oe" }, { new String("ß"), "ss" } };
public static String replaceUmlaute(String orig) {
    String result = orig;

    for (int i = 0; i < UMLAUT_REPLACEMENTS.length; i++) {
        result = result.replace(UMLAUT_REPLACEMENTS[i][0], UMLAUT_REPLACEMENTS[i][1]);
    }

    return result;
}

因此，感谢您的所有答复和帮助.最终，这是纳法斯(带有新的String)和乔普·艾根(正确的替换声明)的混合体.非常感谢您！

So thanks to all your answers and help. It finally was a mixture of nafas(with the new String) and Joop Eggen(the correct replace-Statement). You got my upvote thanks a lot!
