Generic Methods

• Generic method = method with type parameter(s)

• public class Utils
  {
     public static <E> void fill(ArrayList<E> a, E value, int count)
     {
        for (int i = 0; i < count; i++)
           a.add(value);
     }  
  }

• A generic method in an ordinary (non-generic) class
• Type parameters are inferred in call
  

  ArrayList<String> ids = new ArrayList<String>();
  Utils.fill(ids, "default", 10); // calls Utils.<String>fill
