title: Java string - replace multiple spaces by one and then split string into array based on space
body: <p>Suppose I have a string </p>
  
  <pre><code>s ="[    2323.2323 232.3232 0.2 0.3 3232]"
  </code></pre>
  
  <p>I want to split it into an array of strings by space delimiter. I also want to preserve a single space between values and ignore the multiple space. </p>
  
  <p>What would be the regular expression to do this?</p>
