Java 拆分字符串的数字列表

我有一个

String

列表，但没有正则表达式方面的技能。所以我需要你的帮助

第一个字符串：

[begin]
65. This tutorial walks you through a series of exercises to get familiar with Kotlin. 
66. Kotlin Koans are a series of exercises to get you familiar with the Kotlin Syntax.
67. Each exercise is created as a failing unit test and your job is to make it pass. You can play with Koans online or offline by cloning the project on GitHub:
...
[end]

二线

[begin]
63. Download the Koans by cloning the project from GitHub
64. Open up the project in IntelliJ IDEA or your favorite editor. Note: If IntelliJ IDEA prompts you to update the Kotlin library, just click yes.
[end]

和其他字符串

目标： 我需要将每个数字行提取为

字符串

：

String#1 : 63. Download the Koans by cloning the project from GitHub
String#2 : 64. Open up the project in IntelliJ IDEA or your favorite editor. Note: If IntelliJ IDEA prompts you to update the Kotlin library, just click yes.
String#3 : 65. This tutorial walks you through a series of exercises to get familiar with Kotlin. 
String#4 : 66. Kotlin Koans are a series of exercises to get you familiar with the Kotlin Syntax.
String#5 : 67. Each exercise is created as a failing unit test and your job is to make it pass. You can play with Koans online or offline by cloning the project on GitHub:

各位将非常感谢任何有关skill up regex的在线培训工具。

此工具适用于javascript

/^（\d+）/gm

---

我希望您的regexp应该如下所示

^（\d+.*）

在哪里

你可以在：rubular.com上玩它

我走这条路：

定义一个类来分析行和文本。。（您需要它来排序最终的

列表

）

.

直接用谷歌搜索“regex”，你就能找到你需要的所有工具。“英雄看起来不容易：D”是什么意思？英雄们可能会使用必要的资源来完成你拒绝做的事情。像这样的事情？嘘，我糊涂了。你想按行号重新排序吗？真正的英雄要求其他人做他们的工作，为他们解决他们的问题，不费吹灰之力。愿上帝保佑这些勇敢的灵魂。

^ - start of line
\d+ - any non zero amount of numbers
.*  - any symbols
( ) - grouping

class TextLine implements Comparable<TextLine> {

    private int line;
    private String lineText;

    public TextLine(int line, String lineText) {
        this.line = line;
        this.lineText = lineText;
    }

    @Override
    public String toString() {
        return "String:" + line + lineText;
    }

    @Override
    public int compareTo(TextLine o) {
        return Integer.compare(this.line, o.line);
    }
}

public class TestApp {

    private List<TextLine> output = new ArrayList<TextLine>();

    public static void main(String[] args) {
        TestApp tt = new TestApp();
        String str = "65. This tutorial walks you through a series of exercises to get familiar with Kotlin. ";
        tt.populateLsit(str);
        str = "67. Each exercise is created as a failing unit test and your job is to make it pass. You can play with Koans online or offline by cloning the project on GitHub:";
        tt.populateLsit(str);
        str = "66. Kotlin Koans are a series of exercises to get you familiar with the Kotlin Syntax. ";
        tt.populateLsit(str);
        str = "63. Download the Koans by cloning the project from GitHub";
        tt.populateLsit(str);
        str = "64. Open up the project in IntelliJ IDEA or your favorite editor. Note: If IntelliJ IDEA prompts you to update the Kotlin library, just click yes.";
        tt.populateLsit(str);
        tt.sortPrint();
    }

    private void sortPrint() {
        Collections.sort(output);
        System.out.println(output);

    }

    private void populateLsit(String str) {
        Matcher match = Pattern.compile("^(\\d+)|(.*)").matcher(str);
        // String r = match.group();
        match.find();
        int i = Integer.parseInt(match.group());
        match.find();
        String s = match.group();
        output.add(new TextLine(i, s));
    }
