Neighborhood Watch News

Neighborhood Watch is one of the oldest and most effective crime prevention programs in the country, bringing citizens together with law enforcement to deter crime and make communities safer. 
 
Sponsored by the National Sheriffs Association (NSA), Neighborhood Watch can trace its roots back to the days of colonial settlements, when night watchmen patrolled the streets. The modern version of Neighborhood Watch was developed in response to requests from sheriffs and police chiefs who were looking for a crime prevention program that would involve citizens and address an increasing number of burglaries.

Launched in 1972, Neighborhood Watch counts on citizens to organize themselves and work with law enforcement to keep a trained eye and ear on their communities, while demonstrating their presence at all times of day and night. (The program took off quickly: in just ten years, NSA data showed that 12 percent of the population was involved in a Neighborhood Watch.) Neighborhood Watch works because it reduces opportunities for crime to occur; it doesnt rely on altering or changing the criminals behavior or motivation.

1A.) hashCode() (javadoc) must also be consistent (if the object is not modified in terms of equals(), it must keep returning the same value).

The relation between the two methods is:

Whenever a.equals(b), then a.hashCode() must be same as b.hashCode().

Lazy loaded objects are subclasses

If your objects are persisted using an ORM, in many cases you will be dealing with dynamic proxies to avoid loading object too early from the data store. These proxies are implemented as subclasses of your own class. This means thatthis.getClass() == o.getClass() will return false. For example:

Person saved = new Person("John Doe");
Long key = dao.save(saved);
dao.flush();
Person retrieved = dao.retrieve(key);
saved.getClass().equals(retrieved.getClass()); // Will return false if Person is loaded lazy
If you're dealing with an ORM using o instanceof Person is the only thing that will behave correctly.

Lazy loaded objects have null-fields

ORMs usually use the getters to force loading of lazy loaded objects. This means that person.name will be null if person is lazy loaded, even if person.getName() forces loading and returns "John Doe". In my experience, this crops up more often in hashCode and equals.

If you're dealing with an ORM, make sure to always use getters, and never field references in hashCode and equals.

Saving an object will change it's state

Persistent objects often use a id field to hold the key of the object. This field will be automatically updated when an object is first saved. Don't use an id field in hashCode. But you can use it in equals.
