a. Write a Java class that declares variables to represent the length and width of a room in feet. Assign appropriate values to the variables—for example, length = 15 and width = 25. Compute and display the floor space of the room in square feet (area = length " width). Display explanatory text with the value—for example, The floor space is 375 square feet. Save the class as Room.java.

b. Convert the Room class to an interactive application. Instead of assigning values to the length and width variables, accept them from the user as input. As output, echo the user's entries as well as displaying the floor space. Save the revised class as Room2.java.
