Simulate a sensor system monitoring a house. Sensor and Dispatcher are Threads. Sensor produces a SensorEvent at random times and adds the event to the EventQueue which is implemented as a queue. The type of event depends on the type of the sensor that produced it. Dispatcher consumes events by removing them from the EventQueue. Consuming an event takes 50 ms and involves outputting on the screen the event information: source (id of the sensor), time and type. 1) Implement the above classes and in Main instantiate 4 sensors, 1 dispatcher and start all of them. Use ReentrantLock for synchronization. Use Executors for implementing the producers and consumers. Implement a second version of the program in which you use a BlockingQueue for sychronization instead of using locks
