The input birth and death rates cannot be negative, the starting population cannot be less than 2, and the number of years greater than 0. If the user enters an invalid value, this program will prompt user to re-enter the value until a valid value has been read.

One of them is distance which type is integer. Another is direction which type Direction. The method should to the following: o If the direction is EAST, set the x-coordinate with adding distance. o If the direction is WEST, set the x-coordinate and subtract distance from x-coordinate. o If the direction is SOUTH, set the y-coordinate with adding distance. o If the direction is NORTH, set the y-coordinate and subtract distance from x-coordinate. • Write a method toString to display the tank coordinates.
