Multiplication
/
Division operation
%
Take over operations, a% b, be the remainder of a b
+ +
Accumulate operations, a + +, the result is equivalent to a = a +1
-
Tired subtraction, a -, the result is equivalent to a = a-1
+ =
Even the addition operation, a + = b, the result is equivalent to a = b + a
-=
With additional operations, a-= b, the result is equivalent to a = b-a

flex data types and java data type correspondence actionscript3.0 to convert data types when the correspondence between
Data type class actionscript data types ——————-
null ——————- null
number ——————- java. lang.number
boolean ——————- java. lang.number, boolean, java.lang.string
string ——————- java. lang.string, java.lang.boolean, boolean, java.lang.character, char, java.lang.number

================================================
converting java to actionscript 3.0 data types correspond to
——————- actionscript3 .0 java data type, data type
null ——————- null
java.lang.number ——————- number

java.lang.number, boolean ——————- boolean
java.lang.string, java.lang.character char [] ——————- string
java.util.collection, java.lang.reflect.array ——————- array
java.util.map, java.util.dictionary ——————- object
org.w3c.dom.document ——————- xml object
Other claess ——————- object
Using lcds call java code in the process of data type conversion is directly occurred without explicit call.
Complement: java in the list, arraylist corresponds to flex where can arraycollection to receive.
eg: connect oracle through java to write a method, returns a arraylist, put the arraylist in general is one of the hashmap. If by remoteobject (or otherwise) to call the method, flex termination is received recognition object, this time can be cast into arraycollection. Then traverse the arraycollection, to obtain the deposit of each data object (java in the hashmap).
flex there are no map class, but if you know java in map of the key, where it can flex as the object of a property to access
