Is there a best practise for converting Strings to the new Java 1.5
enums?

This is my current methodology:

  public void setAssetClass(String assetClass) throws Exception{
       for(AssetClass ac : AssetClass.values()) {
           if(assetClass.equals(ac.toString())) {
               setAssetClass(ac);
               return;
           }
       }
       throw new Exception("Invalid asset class: " + assetClass);
   }

   private void setAssetClass(AssetClass assetClass) {
       this.assetClass = assetClass;
   }
