问如何检测字符串是否至少包含特定语言的一个字符？

 boolean isHindi = false;
 for (char c: myString.toCharArray()) {
     if (Character.UnicodeBlock.of(c) == Character.UnicodeBlock.DEVANAGARI) {
         isHindi = true;
         break;
     }
 }

    boolean isHindi = false;
    for (int k = 0; k < Character.codePointCount(myString, 0, myString.length()); k++) {
        int c = myString.codePointAt(k);
        if (c >= 0x0900 && c <= 0x097F) {  //Hindi uni-codes are within this range
            isHindi = true;
            break;
        }
    }

boolean isHindi = 
    myString.chars().anyMatch(c -> Character.UnicodeBlock.of(c) == Character.UnicodeBlock.DEVANAGARI);
