The animal classthis class represents a an animal residing at a zoo. it has a weight (in pounds),height (in inches), a name, and a color. the methods in the class include constructors,getters, and a tostring. you will finish the implementation of these methods. referto the code documentation.1.getters: you will need to implement getter methods. these get a value (froma member variable) in the animal class. you will make a getter method toreturn each variable (weight, height, name, color). reference getname if youare having issues.2.tostring: you will need to finish the tostring method. this returns a stringcontaining information about an animal. the output string should be of theformat: ” (name) , a ( color )â’colored animal . ( weight ) pounds , ( height ) inches .\n”the height and weight are formatted to 1 decimal place. recall from lab 1how to format strings neatly using string. see the reference sectionfor more about string.format.

Write a program that begins by reading in a series of positive integers on a single line of input and then computes and prints the product of those integers. integers are accepted and multiplied until the user enters an integer less than 1. this final number is not part of the product. then, the program prints the product. if the first entered number is negative or 0, the program must print “bad input.” and terminate immediately. next, the program determines and prints the prime factorization of the product, listing the factors in increasing order. if a prime number is not a factor of the product, then it must not appear in the factorization. sample runs are given below. note that if the power of a prime is 1, then that 1 must appear in t
