Fill in the first line of this SquareTester program so that it declares and initializes a variable mySquare as an instance of a Square class with a side length of 6. public class SquareTester { Public static void main(String[] args) { /* Step 1: declare and initialize a variable mySquare as an Instance of a Square class with a side length of 6 */ _____________________________________ /* Step 2: print out the area of the object referenced by the Variable mySquare using the getArea method */ /* Step 3: print the expected outcome */ } }

Fill in the third line of this SquareTester program so that it prints out the expected outcome. public class SquareTester { Public static void main(String[] args) { /* Step 1: declare and initialize a variable mySquare as an Instance of a Square class with a side length of 6 */ /* Step 2: print out the area of the object referenced by the Variable mySquare using the getArea method */ /* Step 3: print the expected outcome */ _____________________________________ } }
