Question

我需要在使用" "分隔符拆分字符串后添加空格。我需要这样做的原因是因为在下一个String的开头没有添加空格，如下例所示：

"There was nothing so VERY remarkable in that; nor did Alice" +
"think it so VERY much out of the way to hear the Rabbit say to"

下面的代码只拆分字符串（并反转它），但是连接产生以下结果（注意＆＃34; Alicethink＆＃34;连接在一起）：

erehT saw gnihton os YREV elbakramer ni ;taht ron did knihtecilA
ti os YREV hcum tuo fo eht yaw ot raeh eht tibbaR yas

代码：

String[] text = PROBLEM5PARA.split(" ");
String reverseString = "";

for (int i = 0; i < text.length; i++) {

    String word = text[i];
    String reverseWord = "";

    for (int j = word.length()-1; j >= 0; j--) {
        reverseWord += word.charAt(j);
    }

    reverseString += reverseWord + " ";
}

System.out.println(reverseString);

我该如何解决？

编辑：这是整个字符串：

private static final String PROBLEM5PARA =
        "  There was nothing so VERY remarkable in that; nor did Alice" +
                "think it so VERY much out of the way to hear the Rabbit say to" +
                "itself, `Oh dear!  Oh dear!  I shall be late!'  (when she thought" +
                "it over afterwards, it occurred to her that she ought to have" +
                "wondered at this, but at the time it all seemed quite natural);" +
                "but when the Rabbit actually TOOK A WATCH OUT OF ITS WAISTCOAT-" +
                "POCKET, and looked at it, and then hurried on, Alice started to" +
                "her feet, for it flashed across her mind that she had never" +
                "before seen a rabbit with either a waistcoat-pocket, or a watch to" +
                "take out of it, and burning with curiosity, she ran across the" +
                "field after it, and fortunately was just in time to see it pop" +
                "down a large rabbit-hole under the hedge.";

Answer 1

如果原始字符串是

"There was nothing so VERY remarkable in that; nor did Alice" + "think it so VERY much out of the way to hear the Rabbit say to"

您的代码将其视为

"There was nothing so VERY remarkable in that; nor did Alicethink it so VERY much out of the way to hear the Rabbit say to"

在连接之后（在编译中发生，我相信），Alicethink是一个单词，并且无法单独反转Alice和think。

如果这是家庭作业，我认为你的代码目前正在做它应该做的事情。如果有疑问，请询问您的导师。

Answer 2

您的原始字符串也已加入Alice" + "think，您需要将其更新为Alice " +"think或Alice" + " think
