How to remove Arabic hashtags?

I read tweets from Twitter using Twitter4j and I am trying to filter hashtags from it after I take text from it Now I turn it into strings I have this line: "892698363371638784: RT @hikids_ksa: اللعبة خطيرة مرا ويبي لها مرا ويبي لها مرا ويبي لها مرا ويبي لها مو تفكير و مهارة👌🏻💡 متوفرة في # متجر_هاي_كيدز_الالكتروني .. "

I want to remove متجر_هاي_كيدز_الالكتروني as it has a Hashtag after it using java

the problem of my code didn't work on this input: "@kaskasomar هيدا بلا مخ متل متل غيرو بيخون الشعب اللبناني وبيتهمو بالارهاب بس لانرأيو بييات

the سخيف part was not removed for some reason this is my method

static String removeHashtags(String in)
{
    in = in.replaceAll("#[A-Za-z]+","");//remove English hashtags
    in = in.replaceAll("[أ-ي]#+","");//remove Arabic hashtags that have # before it
    return in = in.replaceAll("#[أ-ي]+","");//remove Arabic hashtags that have # after it
}

The problem is that the second line +

applies to the hashtag and not the Arabic characters. Fixed version:

in = in.replaceAll("[أ-ي]+#","");

If you are just trying to remove all hash tags in any language, you can write

in = in.replaceAll("#\\p{IsAlphabetic}+", "");

If you specifically want to remove Arabic hash tags, you can write

in = in.replaceAll("#\\p{IsArabic}+", "");

so you don't have to worry about creating a left and right and right to left regex. This improves the readability of your code.
