Consider the following class definition. public class rectangle{private double length; private double width; public rectangle(){length = 0; width = 0; }public rectangle(double l, double w){length = l; width = w; }public void set(double l, double w){length = l; width = w; }public void print(){system. out. println(length + " " + width); }public double area(){return length * width; }public void perimeter(){return 2 length + 2 width; }}suppose that you have the following declaration. rectangle bigrect = new rectangle();
which of the following sets of statements are valid in java?
(i) bigrect. set(10, 5);
(ii) bigrect. length = 10; bigrect. width = 5;
