Generic Methods

• Generic method: method with a type variable
• Can be defined inside ordinary and generic classes
• A regular (non-generic) method:

  /**
     Prints all elements in an array of strings.
     @param a the array to print
  */
  public static void print(String[] a)
  {
     for (String e : a)
        System.out.print(e + " ");
     System.out.println();
  }

• What if we want to print an array of Rectangle objects instead?

  public static <E> void print(E[] a)
  {
     for (E e : a)
        System.out.print(e + " ");
     System.out.println();
  }
