title: Java - is there an built in function for concatenating the Strings in a String[]?
body: <p>Or a better way than this?</p>
  
  <pre><code>String concat(String[] strings) {
    StringBuilder out = new StringBuilder();
  
    for(String next: strings) {
      out.append(next);
    }
  
    return out.toString();
  }
  </code></pre>
  
  <p>No worries if no, I just feel like there should be a built in?</p>
