Java实现英文句子中的单词顺序逆序输出的方法

import java.io.UnsupportedEncodingException;import java.util.Scanner;public class Main {    public static String reverseWords(String sentence) {        StringBuilder sb = new StringBuilder(sentence.length() + 1);        String[] words = sentence.split(" ");        for (int i = words.length - 1; i >= 0; i--) {            sb.append(words[i]).append(' ');        }        sb.setLength(sb.length() - 1);        return sb.toString();    }    @SuppressWarnings("resource")    public static void main(String[] args) throws UnsupportedEncodingException {        Scanner in = new Scanner(System.in);        System.out.printf("Please input how many lines you want to enter(test by jb51): ");        String[] input = new String[in.nextInt()];        in.nextLine();        for (int i = 0; i < input.length; i++) {            input[i] = in.nextLine();        }        System.out.printf("\nYour input:\n");        for (String s : input) {            System.out.println(reverseWords(s));        }    }}
