在Java中修剪字符串,同时保留完整的单词

public class TrimString {
    public static void main(String[] args) {
        String input = "Hello, World!";
        int maxLength = 10;
        String trimmedString = trimString(input, maxLength);
        System.out.println("Trimmed string: " + trimmedString);
    }

    public static String trimString(String input, int maxLength) {
        if (input.length() <= maxLength) {
            return input;
        }

        int lastSpace = input.lastIndexOf(" ", maxLength);
        if (lastSpace == -1) {
            return input.substring(0, maxLength) + "...";
        }

        return input.substring(0, lastSpace) + "...";
    }
}
