Draw a UML collaboration diagram for the following executions. (9 pts) The program starts by calling receive0 of object mm of class MessageManager and then the mm object does the followings in order. 1. mm receives an outMsg object by calling method parse 0 of an instance of MIMEParser. The parse() method calls the following three methods of object builder of MAPIBuilder in sequence. to(s1; String) from(s2: String) plainText(s3: String) 2. mm calls method send 0 of object outMsg of OutboundMessagelF 3. mm calls the encryptMsgitext:MimeMsg) method of class Encrypter, which starts up two asynchronous threads running concurrently as below: - One thread calls method validateMIMEStructure0 of an object of MIMEParser. The other calls method getKey(to:String) of object km of KeyManager
