把句子中的单词字母颠倒过来

Question

对于我的程序，我想颠倒一行文本中的字母。但是我不想颠倒句子中单词的顺序。例如，当我输入：“这是一个字符串”

我得到了一个siht

但我想要的是

public static String reverseWordCharacters(String text1) {
        String reverse = "";
        int length = text1.length();
        for (int i = length - 1; i >= 0; i--) {
            reverse = reverse + text1.charAt(i);
            System.out.println();
        }
        return reverse;
    }

}

Answer 1

这可能是最简单的方法

import java.util.*;
public class ReverseString{
public static void main(String[] args){
    Scanner sc = new Scanner(System.in);
    System.out.print("Enter any Sentence: ");
    String sentence = sc.nextLine();
    String[] stringArray = sentence.split(" ");
    for(int i = 0; i<stringArray.length; i++){
        String temp = new StringBuilder(stringArray[i]).reverse().toString();
        System.out.print(temp+" ");
    }
    }
}

Commons Lang的StringUtils类有这样的方法：

Answer 3

String sentence = "This is a string";
String[] words = sentence.split(" ");
String invertedSentece = "";
for (String word : words){
    String invertedWord = "";
    for (int i = word.length() - 1; i >= 0; i--)
        invertedWord += word.charAt(i);
    invertedSentece += invertedWord;
    invertedSentece += " ";
}
invertedSentece.trim();
