基于模式java拆分给定的文本

Question

以下是我的文字

This is my first java Program. I am new to java program. but my program is successfully running without any. issues. Thanks to all

它应该像

一样分开

This is my first java Program.
I am new to java program. but my program is successfully running without any. issues.
Thanks to all.

正则表达式应采用以下模式

1.dot
2.followed by space
3.followed by capital letter word(not lowecase)

我试过这个

1. \\.\\w[A-Z]
2. \\.\\s\s[A-Z]
3. \\.(?!\\w)

但未能得到它。

Answer 1

请尝试以下代码：

String text = "This is my first java Program. I am new to java program. but my program is successfully running without any. issues. Thanks to all";
Pattern pattern = Pattern.compile("(?<=\\.)\\s+(?=[A-Z])");
String[] lines = pattern.split(text);
for (String line : lines) {
    System.out.println(line);
}

输出：

This is my first java Program.
I am new to java program. but my program is successfully running without any. issues.
Thanks to all

使用String.split（）方法拆分字符串（返回一个数组）。
