Question

In java

1. Monkey Business (10 points) A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 x 5 array, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey. Then, it should create a report that includes the following information: Average amount of food eaten per day by the whole family of monkeys. The least amount of food eaten during the week by any one monkey. • The greatest amount of food eaten during the week by any one monkey. Input Validation: Do not accept negative numbers for pounds of food eaten. A user is required to re-enter the input until the input is valid.
