Java to Scala...

Interesting, and cool... :-)

    boolean nameHasUpperCase = false; // This is Java
    for (int i = 0; i < name.length(); ++i) { 
         if (Character.isUpperCase(name.charAt(i))) { 
             nameHasUpperCase = true; 
             break; 
         } 
    }

in Java to

    boolean nameHasUpperCase = !name.toLowerCase().equals(name);

in Java to

    val nameHasUpperCase = name.exists(_.isUpperCase) 

in Scala.
