Adding a char array through dedicated for loop instead of a string

[Luro02]

What it does

This lint seems more like an edge-case, so the value of it, is questionable.
The main idea is that some code can be simplified by invoking the String constructor for char arrays and then using the string value instead.

Example

String buildString(StringBuilder output, char[] array) {
    for (char element : array) {
        output.append(element);
    }
    return output.toString();
}

Could be written as:

String buildString(StringBuilder output, char[] array) {
    output.append(new String(array));
    return output.toString();
}

Similarly this could detect redundant conversions to string like:

String buildString(char[] array) {
    String result = "";
    for (char element : array) {
        result += element;
    }
    return result;
}

Could be written as:

String buildString(char[] array) {
    return new String(array);
}
