本文实例讲述了Java实现英文句子中的单词顺序逆序输出的方法。分享给大家供大家参考,具体如下:
题目要求:给定n行的英文句子,要求输出句子中逆序单词后的句子,如:
输入:n=3
I love you
How are you
My name is Liming
输出:
you love I
you are How
Liming is name My
依据Java语言给我们提供的拆分空格间隔的单词的方法(split(" ")),倒序输出即可;
实现代码:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23

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)); } } } |
运行结果:
希望本文所述对大家java程序设计有所帮助。
