JAVA to Flex relation

Question

Now, we usually use Remote Class Annotation when we convert
into the JAVA object from
Action Script 3 Class Object.
And we doubt when we convert that the declaration of the
[public] is always necessity or not,
about the scope of variable declaration in the class of JAVA
and the class of Action Script 3.
Please let us know, we should declare of the [public] or
not.

Answer 1

From ActionScript to Java, only public, non-static,
read-writable properties (that is, properties that have both a
public get and set accessor defined) and public, non-static, vars
are serialized.
From Java to ActionScript, only public, non-static,
non-transient, read-writable bean properties (that is, properties
that have both a public getter and setter methods defined) and
public, non-static, non-transient fields are serialized.
For custom serialization requirements, consider using
matching flash.utils.IExternalizable and java.io.Externalizable
implementations that are also registered with the appropriate
[RemoteClass(alias="...")] metadata.
There are a few other options on the server for customizing
serializaiton of strongly typed objects (via the
PropertyProxyRegistry), but this is a little out of scope for this
question.
