title: Regex to replace all numbers after first 3 numbers
body: <p>I am using the java regex engine and need a way to remove all numbers after the first 3 digits in the string. I have tried a positive look behind but that didnt work.</p>
  
  <p>Here is the type of data i have </p>
  
  <pre><code>213-333-4444
  
  233.444.5556
  
  (636) 434-5555
  </code></pre>
  
  <p>This the result i am trying to reach:</p>
  
  <pre><code>213-222-2222
  
  233.222.2222
  
  (636) 222-2222
  </code></pre>
  
  <p>So the regex would look for the first 3 digits and past that replace all numeric charecters with 2s.</p>
