title: java Regex Question
body: <p>In Java - I need to search/validate an input string for a number or for a specific string. it must be one of them.
  For example - If I have this input lines:</p>
  
  <pre><code>cccccccc 123 vvvvvvvvv jhdakfksah
  cccccccc ABC vvvvvvnhj  yroijpotpo
  cccdcdcd 234 vcbvbvbvbv lkjd dfdggf
  ccccbvff ABC jflkjlkjlj fgdgfg
  </code></pre>
  
  <p>I need to find 123, ABC, 234, ABC</p>
  
  <p>to look for the number I could use regex: "\d+" but to look for either of them How can I combine them?</p>
