Please Answer both (a) and (b). They are two parts of the same question. Will give thumbs up and good review if both parts are answered.

Create a program to calculate the area and perimeter of a square - the program consists of (a) A class that accepts the length of the square and encapsulates calculation of area & perimeter The class should have two constructor, one that accepts length as the argument and another that doesn't accept any arguments. . Methods: o Set length o Return area o Return perimeter Assume length is of type "integer" (b) A test program that uses the square class (from the step above) (b) A test program that uses the square class (from the step above) . Create a square object (instance of class) that sets length to 7 (through the constructor) Create another square object, that calls the constructor without any arguments; set the length of the square to 10 Print the area and perimeter of both squares o 1st square: area : 49, perimeter: 28 o 2nd square: area: 100, perimeter: 40
