title: Using Java RegEx to find words that start with Upper case and contain lower case
body: <p>So I am using Java Regex to find acronyms.  Most of the Acronyms I am getting are all uppercase, which is fine I have the reg ex for that what I need is a regex for words that will have one lower case letter and the rest are upper case like CCaRS.  What Regex could I use for this?  Below is a sample of the All upper case Regex I am using.</p>
  
  <pre><code> String twoPlusUCRegEx = "[A-Z][A-Z]+";
  </code></pre>
  
  <p>Sample Acronyms: CCaRS, MiDAE</p>
