Java implements the reverse order output of word order in English sentences

This article describes the method of Java implementing the reverse order of word order in English sentences. Share it for your reference, as follows:

Question requirements: Given an English sentence with n lines, the sentences after the reverse order words in the sentence are required, such as:

Input: n=3
I love you
How are you
My name is Liming

Output:

you love I
you are How
Liming is name My

According to the method (split(" ")) provided to us by Java language, you can output in reverse order;

Implementation code:

 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)); } }}
