Q1: Write the Java code corresponding to the following UML diagram. The class School implements the interface Building. The method computeArea returns the area of the building as width * length. After that, add a testing class with a main method which defines an arrayList that contains three objects. From the main method, print the area of all the three objects. Building > + computeArea() : double + toString() : String School classroomNum: int width: double - length: double + School(classroomNum: int, width: double, length: double) + computeArea() : double + toString() : String
