An elaborated solution based on Qtax's answer:

String s = "java html. .net node.js php.";
System.out.println(s);
s = s.replaceAll("(\\w)\\.(?!\\S)", "$1");
System.out.println(s);

Output:

java html .net node.js php

If you're going to use a regular expression, I'd recommend using a word boundary. 

 \.\B

This matches a literal dot at the end of a word boundary only.

You can do:

String repl = "java html. .net node.js php.".replaceAll("\\.(?!\\w)", "");

// java html .net node.js php

for(String str : input.split(" "))
{ 
     if(str.charAt(str.len - 1) == '.')
         str = str.substr(0, str.len - 2);

     //do something with str
}

I would avoid regular expressions if at all possible as they are much slower.

Depending on your definition of word you could replace:

(\w)\.(?!\S)

with $1. Which would remove all . at the end of a word followed by a space or end of string.
