Local Methods

---

• Remote objects can have methods that are local: Not part of any Remote interface.
• The example below, a minimal modification of the Hello World application, illustrates this.
• Modifications are indicated in red.
• Here is the modified method server; the client, HelloClient, and the interface Hello are unchanged.
