java中的大量地图，我应该把它放在哪里？

Question

也许这是基础知识，但我对这件事情不熟悉。 我有一组令牌，我想用地图将俚语代币替换为正确的单词。我应该把这5000张地图放在我的java中

public static Map<String, String> replacements;
    static {
            replacements.put("07734","hello");
            replacements.put("0day","software illegally obtained before it was released");
            replacements.put("0noe","oh no");
            replacements.put("0vr","over");
            replacements.put("10q","thank you");
            ............

这是我替换所有令牌的代码，但我仍然会遇到一些错误。

                for (Map.Entry<String, String> replacement : replacements.entrySet() ){
                    int start = sb.indexOf(replacement.getKey(),0);
                    while (start >= 0){
                        int end = start + replacement.getKey().length();
                        sb.replace(start, end, replacement.getValue());
                        start = sb.indexOf(replacement.getKey(), start + replacement.getValue().length());
                    }
                }
