title: Best way to check multiple strings in an if statement
body: <p>What is the cleanest way of checking multiple strings in an if statement, I want to be able to check to see if the users country is one that uses the euro which I will put in the ("???") .Because this works.</p>
  
  <pre><code>if (usercountry.equals("FRA") || usercountry.equals("FRA")|| 
      usercountry.equals("FRA") || usercountry.equals("FRA") || 
      usercountry.equals("FRA") || usercountry.equals("FRA") || 
      usercountry.equals("FRA") || usercountry.equals("FRA") ||
      usercountry.equals("FRA")) {
          costpermile = costpermile*1.42;   //(costpermile=£)   (costpermile*1.42=Euros)
  }
  </code></pre>
  
  <p>but it looks awful</p>
  
  <p>BTW im not checking France over and over again its still prototype code and so I haven't entered every euro country without checking if there was a better way first.</p>
