 When AmbientTalk values and Java values cross language boundaries (e.g. when they are passed as arguments of or return values from a method that is invoked from the other language), these values are converted. AmbientTalk features a number of built-in conversions that maps AmbientTalk's native language values onto JVM native data types and vice versa. The following tables show the conversion rules for going from Java to AmbientTalk and from AmbientTalk to Java. When AmbientTalk values and Java values cross language boundaries (e.g. when they are passed as arguments of or return values from a method that is invoked from the other language), these values are converted.

 Note that non-native Java or AmbientTalk objects are represented in the other language by means of "wrappers". The task of these "wrappers" is to represent an object written in one language to act as if it were an object written directly in the other language. Note that non-native Java or AmbientTalk objects are represented in the other language by means of "wrappers".

 +In the last conversion rule of the second table, ''I'' represents a Java interface type. ''I'' is determined by a static type declaration in Java.
