[android-developers] Re: Shared preference from non activity class
I'm not happy with the other answers, though they are not really incorrect. (The object with a hashmap of properties thing that Hari mentions is not really a JavaBean, though some packages can use maps as if they were implicitly a JavaBean). I'd rather explain it from a minimalist point of view. A JavaBean is, at a minimum, an object with data that you access with public getter and setter methods. e.g. public void setFoo(String foo) and public String getFoo() -- although it doesn't need to be strings. This corresponds to a String- valued property named 'foo'. There's more layered on that, in terms of facilities to manipulate and work with them, but when someone says bean class, that's all you really know they're talking about. That's enough to be a JavaBean.

I have no idea what a bean class is. Bean class is an old name for awhat we call not a POJO. Android essentially leaves only the PropertyChangeEvent, from the old java.beans package.

Hi Hari. Just my two cents but if you mean the Java Bean specification, then the spec is a J2SE technology ( http://www.oracle.com/technetwork/java/javase/documentation/spec-136004.html ) and comes into world long before the people start to thinking in terms of EJBs and so on.

Re: [android-developers] Re: Shared preference from non activity class
Bean class is a pojo. You have private instance variables, with public get/set methods. A property is an instance field with a get/set method. I forget though if you need both.. there are some cases where you may want to make a mutable property by using a constructor to set it, then only have a getter so it can't be changed.
