In Java please

You are asked to implement a "message queue" class using Java. The following figure depicts a message queue connector class, followed by the detailed specifications of operations. The message queue connector class has sendO and receive), and the size of queue is 3. You can declare additional variables in the message queue class if necessary To test your implementation, your program should create two separate threads, a producer thread and a consumer thread. The producer thread sends a message having a structure, (string, integer) e.g., ("add", 3) or ("multiply", 7) to a consumer thread via a message queue. There is a SimpleCalculation class that has two operations, add() and multiply(). You should implement the SimpleCalculation class. When the consumer thread receives a message from the queue, it extracts the message and then calls one of operations on the SimpleCalculation class depending on the message. For example, the consumer thread calls the add) operation if it receives a message like ("add", 3), while it calls the multiply0 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 thread and displays the result on the screen. The multiply0 operation multiplies the integer by 10 and displays the result on the screen. The producer thread should displays the messages on the screen before it sends the messages to the consumer thread. The messages are ("add", 4), multiply", 1), "multiply", 8), ("add", 2) ("add", 3), ("add", 99), ("multiply", 53) sent to the consumer Please make a zip file containing all source codes (java files) for this assignment and submit it to blackboard
