Write a program to calculate the area of four shapes (Rectangle, triangle, circle and square). The program to present the user with a menu where one of the shapes can be selected. Based on the selection made, the user enters the proper input, the program validates the input (i.e all entries must be greater than zero). Once the input is entered and validated, the intended area is calculated and the entered information along with the area are displayed. Area of the Square = Side ^2 Area of the Rectangle = Length * Width Area of the Triangle = ½ Base * Hight Area of the Circle = Pi * R^2 You MUST apply the following to your program: 1) A switch statement to present the selection menu 2) If statement to validate the input for (entries must be greater than 0) Hand in the following: a) Source code, a java file b) Screenshots of all output scenarios. ** use printf ** add comments
