Question 2. Write your solution in file Q2.java. Use Q2Test.java to test your solution. Write two methods named findArea that take side lengths of a square or a rectangle as parameters. findArea method must return the area of a square if there is only one parameter. If there are two parameters, findArea method returns the area of a rectangle.

Example

findArea(2) ?> 4

findArea(3) ?> 9

findArea (2 , 3) ?> 6

findArea (4 , 5) ?> 20
