public class Person {
   private Address address;

   // getters & setters
}

public class Address {
   private StreetName streetName;

   // getters & setters
}

public class StreetName {
   private String name;
}

And you type the following:

StreetName streetName = person.

When pressing Ctrl+Shift+Space once, nothing will happen, since no methods on person exists which are compatible with the StreetName type. However, pressing it twice will automatically find the getStreetName in the Address class, so the final result will look like this, which is a real timesaver, especially in an environment with loads of domain classes (instead of using Strings for names, etc). The final result is shown below!

StreetName streetName = person.getAddress().getStreetName()
