如何在java中拆分带问号、点和感叹号的字符串

如何使用分隔符作为问号、点和感叹号将其拆分为字符串数组。然后在每个大写字符前加一个空格。之后，将该字符设置为小写

String one = "ATrueRebelYouAre!EveryoneWasImpressed.You'llDoWellToContinueInTheSameSpirit?";

成功了

    String one = "ATrueRebelYouAre!EveryoneWasImpressed.You'llDoWellToContinueInTheSameSpirit?";

    String oneWithSpaces = one.replace("!","! ").replace("?","? ").replace(".",". ");
    String[] splitedWithDelimeters = oneWithSpaces.split(" ");


    for (int j = 0; j < splitedWithDelimeters.length; j++) {

        String[] str = splitedWithDelimeters[j].split("(?=[A-Z])");



        for (int i = 0; i < str.length; i++) {
            if (i == 0) {
                System.out.print(str[i] + " ");
            } else if (i > 0) {
                System.out.print(str[i].toLowerCase() + " ");
            }
        }
    }

String one=“aturebelyouare！每个人都已按下。您是否愿意继续进行Messpirit？”；
字符串oneWithSpaces=1.replace（“！”，“！”）.replace（“？”，“？”）.replace（“.”，”）；
字符串[]splitedWithDelimeters=oneWithSpaces.split（“”）；
对于（int j=0；j0），则为else{
System.out.print（str[i].toLowerCase（）+“”）；
}
}
}

对于使用多个分隔符进行拆分，可以使用正则表达式或运算符：

String[] tokens = one.split("\\?|\\.|\\!");

要在每个大写字母前加空格，请执行以下操作：

String two = "";
for (int i = 0; i < tokens.length; i++) {
    String phrase = tokens[i];
    String outputString = "";
    for (int k = 0; k < phrase.length(); k++) {
        char c = phrase.charAt(k);
        outputString += Character.isUpperCase(c) ? " " + c : c;
    }
two += outputString + " ";
}
two = two.replaceAll("\\s+", " ");

但你也可以这样做：

String two = "";
for (int k = 0; k < one.length(); k++) {
    char c = one.charAt(k);
    two += Character.isUpperCase(c) ? " " + c : c;
}
two = two.replaceAll("\\s+", " ");
System.out.println(two);

使用。哪里？=是积极的前瞻，你试过什么了吗？这听起来像是我的任务。我试了两天。我已经厌倦了。我尝试了用正则表达式吐痰，我尝试了替换方法，我尝试了将字符串转换为字符数组。至少，编辑您的问题并显示一个包含所有案例的输入示例，以及预期的输出。非常感谢。还有，在这之后如何使除第一个字母以外的所有字母都小写？您可以像回答一样，或者将所有字母都设置为小写，然后找到分隔符的索引，并将它们后面的第一个字母改为大写

String two = "";
for (int k = 0; k < one.length(); k++) {
    char c = one.charAt(k);
    two += Character.isUpperCase(c) ? " " + c : c;
}
two = two.replaceAll("\\s+", " ");
System.out.println(two);

A True Rebel You Are! Everyone Was Impressed. You'll Do Well To Continue In The Same Spirit?

    List<String> collect = Arrays.stream(one.split("(?<=[?.!])"))
    .map(sentence -> sentence.replaceAll("(?=[A-Z])", " ").trim() )
    .collect(Collectors.toList());
