You are asked to implement a "message buffer and response connector" class using Java programming language. The following figure depicts a message buffer and response connector class, followed by the detailed specifications of operations. The message buffer and response connector class has three operations, send0, receive), and replyO To test your implementation, your program should create two separate tasks (threads), a producer task and a consumer task. The producer task sends a message having a structure, (string, integer) e.g., ("add", 3) or (multiply", 7) - to a consumer task via a message buffer and response connector. The consumer task encapsulates a SimpleCalculation class that has two operations, add0 and "multiply()O. You should implement the SimpleCalculation class as well. When the consumer task receives a message from the connector, it extracts the message and then calls one of operations on the SimpleCalculation class depending on the message. For example, the consumer task calls the add0 operation if it receives a message like ("add", 3), while it calls the multiply) operation if it receives a message like ("multiply", 3). The add0 operation in the SimpleCalculation adds 10 to the integer in a message from the producer task and returns the result. The multiply0 operation multiplies the integer by 10 and returns the result. The producer task should print out the messages before it sends the messages to the consumer task. The messages are ("add", 1), ("multiply", 1), ("multiply", 2), ("add", 2), ("add", 3), ("add" 4), ("multiply", 3) sent to the consumer. Also the producer task should print out the results received from the consumer task
