我在 JAVA 中遇到问题。我试图让字符串向后打印每个单词。

示例:Hello World 将是“olleh dlrow”

下面是我的类(class)。谢谢您的帮助。

public class ReadReverse {

    String message = "Hello nice to meet you in CS102";
    String[] myStrings = message.split(" ");  //Makes an array of the words split up by spaces
    String result = "";

    {
        // gets the length of the array and splits it up by each word
        for (int i = 0; i < myStrings[i].length(); i++) {
            message.push(myStrings[i].at(i));
            // sets th length to the length of the word
            int length = message.length();
        //          pops the letter out into the new stack 
            for (i = 0; i < length; i++) {
                result += myStrings;
            }
            // checks to see if it is at the end of the string. 
            if (i != message.length() - 1) {
                result += " ";
            }

        }
    }
}

您可以通过多种方式实现字符串反转。

看看这个:

 class ReverseString
    {
        public static void main(String[] args)
        {
            String input = "Hello world";
            String[] words = input.split(" ");
            String reversedString = "";
         for (int i = 0; i < words.length; i++)
        {
           String word = words[i]; 
           String reverseWord = "";
           for (int j = word.length()-1; j >= 0; j--) 
       {
            reverseWord = reverseWord + word.charAt(j);
       }
       reversedString = reversedString + reverseWord + " ";
    }
    System.out.println(input);
    System.out.println(reversedString);

    }

}
