## Static Methods

- Don't operate on objects
- Example: `Math.sqrt`
- Example: factory method

      public static Greeter getRandomInstance()

      {

         if (generator.nextBoolean()) // note: generator is static field

            return new Greeter("Mars");

         else

            return new Greeter("Venus");

      }

- Invoke through class:

      Greeter g = Greeter.getRandomInstance();

- Static fields and methods should be rare in OO programs
