title: Java equivalent for C++'s "std::string::find_first_of"
body: <p>is there any Java equivalent for C++'s "std::string::find_first_of"?</p>
  
  <pre><code> string string1( "This is a test string!");
   int location = string1.find_first_of( "aeiou" );
   //location is now "2" (the position of "i")
  </code></pre>
  
  <p>what is the easiest way to achieve this same functionality?</p>
  
  <p>edit: also the proposed solution have to work for Android.</p>
