如何将二维字符数组转换为字符串数组

public class ArrayConversion {
    public static void main(String[] args) {
        char[][] charArray = {{'H', 'e', 'l', 'l', 'o'}, {'W', 'o', 'r', 'l', 'd'}};
        String[] stringArray = convertToStringArray(charArray);
        for (String str : stringArray) {
            System.out.println(str);
        }
    }

    public static String[] convertToStringArray(char[][] charArray) {
        int rows = charArray.length;
        int cols = charArray[0].length;
        String[] stringArray = new String[rows];

        for (int i = 0; i < rows; i++) {
            StringBuilder sb = new StringBuilder();
            for (int j = 0; j < cols; j++) {
                sb.append(charArray[i][j]);
            }
            stringArray[i] = sb.toString();
        }

        return stringArray;
    }
}
