title: Remove special characters and numbers from a string but ignore the white spaces between the words?
body: <p>I want a java regex that could convert this simple sentence like this:</p>
  
  <pre><code>1) I am a (happy) person!!!
  </code></pre>
  
  <p>into</p>
  
  <pre><code>I am a happy person.
  </code></pre>
  
  <p>i.e. ignore all the numbers and special characters but ignore the white space between the words.</p>
  
  <p>I am using this regex right now:</p>
  
  <pre><code>("\\P{L}", "")
  </code></pre>
  
  <p>but it is giving a output like:</p>
  
  <pre><code>Iamahappyperson
  </code></pre>
  
  <p>Thanks for your help!!</p>
