Creating a HashMap using unicode in java

Question

I would like to create a map with japanese character. eg,

    Map<String, String> map = new HashMap<String, String>();
    map.put("あ","ア");
    map.put("え","イ");
    map.put("お","オ");
    map.put("え","エ");
    map.put("お","オ");
    String str = "あaいiうuえeおo";

Result = アaイiウuエeオo

But I want to put only unicode for japanese characters and I want to compare input string with key of map, then change it to respective value. How do I change each letter of String str to unicode. How do I compare each letter in a String with keys of a Map using unicode? If each letter exists as a key of the map, change it with respective map value. Thanks.

You can loop through each of the keys in your map and call String#replaceAll() for each of the respective keys and values.

As for turning the resulting value into unicode you can view this post: Get unicode value of a character .
