title: Java Regex Remove comma's between numbers from String
body: <p>I am trying to parse a string, to remove commas between numbers. Request you to read the complete question and then please answer. </p>
  
  <p>Let us consider the following string. AS IS :)</p>
  
  <p><em>John loves cakes and he always orders them by dialing "989,444 1234". Johns credentials are as follows" 
  "Name":"John", "Jr", "Mobile":"945,234,1110"</em></p>
  
  <p>Assuming i have the above line of text in a java string, now, i would like to remove all comma's between numbers. I would like to replace the following in the same string: 
  "945,234,1110" with "9452341110" 
  "945,234,1110" with "9452341110"
  without making any other changes to the string. </p>
  
  <p>I could iterate through the loop, when ever a comma is found, i could check the previous index and next index for numbers and then could delete the required comma. But it looks ugly. Doesn't it? </p>
  
  <p>If i use Regex "[0-9],[0-9]" then i would loose two char, before and after comma. </p>
  
  <p>I am seeking for an efficient solution rather than doing a brute force "search and replace" over the complete string. The real time string length is ~80K char.  Thanks. </p>
