Simulate a Local Area Network. You have computers that are threads and produce messages. Each computer is defined by a MAC. The message has a content ( a string), the destination MAC and the origin MAC (of the computer that produced it). When a computer produces a message, it sends it to the waiting queue inside the switch which is also a thread. The switch maintains a Map which it completes each time it receives a message from a computer not in the map. When the switch receives a message it consumes it from the waitingQueue and has two possibilities: The Destination MAC is in the switch's map. Then the message is sent to the computer with the corresponding MAC. The Destination MAC is not in the switch's map. Then the message is sent to all the computers When a computer receives a message it prints it on the screen. Each Computer creates a new message each 20 ms with a random Destination MAC to a total of 10 messages. Implement the classes and create a Main class in which you will instantiate 5 computers and 1 switch
