1. To keep the park running smoothly, we need to keep track of the health of all dinosaurs. We need to identify any ill dinosaurs. Using a stream of Dinosaur objects, filter out dinosaurs that are ill (assuming the isIll() method exists the in Dinosaur class), map them to their names, and collect the results in a list. Lastly, print out this list of names of the dinosaurs that need immediate attention.
2. Managing a dinosaur park of this size involves handling large amounts of data. To make an announcement in the park about dinosaur feeding times, create a list of dinosaurs, convert it into a stream, and use the map() function to get a list of dinosaur names. Then, use the forEach terminal operation to print out a message for each dinosaur’s feeding time.
3. Keeping track of the total food required for all the dinosaurs can be tricky. Suppose you have an array of weights of all dinosaurs. Convert it into an IntStream and use the sum method to get the total weight...
