Java正则表达式不会删除点

Question

我正在尝试删除“。” 在文本中，并将其替换为“。”。

我的代码：

System.out.println(TextHandler.class.toString() + " removeExcessiveSpaces E2 " + text);
while (text.contains("\\. \\.")) {
    text = text.replaceAll("\\. \\.", ".");
}
System.out.println(TextHandler.class.toString() + " removeExcessiveSpaces E3 " + text);

文字输入：

"from the streets' fit but you know it. . this is just another case of female stopping play,. in an otherwise total result of a holiday. by m-uhjuly 04, 2006. . 8 . 42 . .. .... . . . . . . . . <script>//<![cdata["

预期产量：

"from the streets' fit but you know it this is just another case of female stopping play,. in an otherwise total result of a holiday. by m-uhjuly 04, 2006. . 8 . 42 .. <script>//<![cdata["

观察到的输出：

from the streets' fit but you know it. . this is just another case of female stopping play,. in an otherwise total result of a holiday. by m-uhjuly 04, 2006. . 8 . 42 . .. .... . . . . . . . . <script>//<![cdata[

（与输入没有区别）

为什么不起作用？

Answer 1

String#contains 不希望正则表达式只是纯字符串。

因此使用：

if (text.contains(". .")) {
    text = text.replaceAll("\\. \\.", ".");
}

或简单地使用String#replace：

text = text.replace(". .", ".");
