An instance variable name of type String, initialized to the empty String. An instance variable score of type int, initialized to zero. A method called setName that has one parameter, whose value it assigns to the instance variable name. A method called setScore that has one parameter, whose value it assigns to the instance variable score. A method called getName that has no parameters and that returns the value of the instance variable name. A method called getScore that has no parameters and that returns the value of the instance variable score.

Write a program called assignment3 (saved in a file assignment3.java) that computes the greatest common divisor of two given integers. one of the oldest numerical algorithms was described by the greek mathematician, euclid, in 300 b.c. it is a simple but very e↵ective algorithm that computes the greatest common divisor of two given integers. for instance, given integers 24 and 18, the greatest common divisor is 6, because 6 is the largest integer that divides evenly into both 24 and 18. we will denote the greatest common divisor of x and y as gcd(x, y). the algorithm is based on the clever idea that the gcd(x, y) = gcd(x ! y, y) if x > = y and gcd(x, y) = gcd(x, y ! x) if x < y. the algorithm consists of a series of steps (loop iterations) where the “larger” integer is replaced by the di↵erence of the larger and smaller integer. this continues until the two values are equal. that is then the gcd.
