Java regex does not remove dots

I am trying to remove "." in the text and replace it with ".".

My code:

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

text input:

"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["

Expected Result:

"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["

Observable output:

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[

(no difference from input)

Why isn't it working?

String#contains

doesn't expect regex to be just a simple string.

so use:

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


Or just use String#replace

:

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

Try the following:

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


I hope this helps you!

contains

doesn't use regex, so contains("\\. \\.")

you should use instead contains(". .")

.

But replace the series . . . . .

with one .

instead of the ineffective

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

because on each iteration it needs to start from the beginning of the line, you can use

text = text.replaceAll("\\.( \\.)+", ".");
