从java中的字符串数组中删除所有非字母字符

public class RemoveNonAlphabets {
    public static void main(String[] args) {
        String[] inputArray = {"Hello, World!", "Java101", "Test@case"};
        String[] resultArray = removeNonAlphabets(inputArray);

        for (String s : resultArray) {
            System.out.println(s);
        }
    }

    public static String[] removeNonAlphabets(String[] inputArray) {
        String[] resultArray = new String[inputArray.length];
        for (int i = 0; i < inputArray.length; i++) {
            resultArray[i] = inputArray[i].replaceAll("[^a-zA-Z]", "");
        }
        return resultArray;
    }
}
