title: Java string replaceAll regex
body: <p>Hi I want to remove certain words from a long string, there problem is that some words end with "s" and some start with a capital, basically I want to turn:</p>
  
  <p><code>"Hello cat Cats cats Dog dogs dog fox foxs Foxs"</code></p>
  
  <p>into:</p>
  
  <p><code>"Hello"</code></p>
  
  <p>at the moment I have this code but I want to improve on it, thanks in advance:</p>
  
  <pre><code>                    .replace("foxs", "")
                      .replace("Fox", "")
                      .replace("Dogs", "")
                      .replace("Cats", "")
                      .replace("dog", "")
                      .replace("cat", "")
