title: Java REGEX for only numbers
body: <p>Im working on a personal custom text editor for mysql and this is my issue:</p>
  
  <p><a href="https://i.stack.imgur.com/t96LR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/t96LR.png" alt="enter image description here"></a></p>
  
  <p>This is what im currently using, it will highlight any number, i want to exclude  numbers directly concatenated to any letter [A-Za-z], any other symbol is not important since some of them are aritmetic symbols.</p>
  
  <p><code>private static final String NUMBER_PATTERN = "[0-9]+";</code></p>
