  <pre><code>val content = "bala.ba* muthu.t@ jiang.xin="
  </code></pre>
  
  <p>How to filter of those junk char(*, @ &amp; = ) in Scala? </p>
  
  <p>For now I am using java substring, which may not the best for scala.</p>
  
  <p>I also tried</p>
  
  <pre><code>filter (_ != "*" ) filter (_ != "@") filter (_ != "=")
  </code></pre>
  
  <p>Don't feel thats the right way</p>
  
  <p>I would like to go with best functional way</p>
  
  <p>Thanks in advance guys...</p>
