Question

only the Java programInstructions:

This project has three parts. Remember to make a copy of this project so you can refer to it when completing the other phases.

Review the sample program before starting this project. The sample program does not exactly match the requirements for this project, so some critical thinking will still be required; however, it is a good thing to reference before starting the project.

Project 2 is a continuation of Project 1. Modify the code from Project 1 in the following ways:

Step 1: Add code to prompt the user to enter the name of the room that they are entering information for.

Step 2: Add Input Validation to the code using the following rules:

• The length of the room cannot be less than 5 feet
• The width of the room cannot be less than 5 feet
• The user's menu selection for the amount of shade should be 1, 2, or 3.

If the user's input is invalid, the program should display an appropriate error message and prompt the user to re-enter their input. The user should be given an unlimited amount of attempts to enter valid input

Step 3: Add code to have the program ask the user if they would like to enter information about another room after the information for a previous room has been processed and displayed. The user should be able to enter a "y" or "Y" to indicate that they want to enter information about another room. See the Sample Input and Output for how to format this.

Step 4: After the user has indicated that they do not wish to enter information about another room, the program should output the number of rooms that have been entered and then stop executing.

Sample Input and Output (user input is in bold) - The output of your program should match the formatting and spacing exactly as shown

Please enter the name of the room: Guest Bedroom
Please enter the length of the room (in feet): 15.5
Please enter the width of the room (in feet): 10
What is the amount of shade that this room receives?

1. Little Shade
2. Moderate Shade
3. Abundant Shade

Please select from the options above: 3

Air Conditioning Window Unit Cooling Capacity

Room Name: Guest Bedroom
Room Area (in square feet): 155.0
Amount of Shade: Abundant
BTUs Per Hour needed: 4,950

Would you like to enter information for another room (Y/N)? Y

Please enter the name of the room: Kitchen
Please enter the length of the room (in feet): 20
Please enter the width of the room (in feet): 15
What is the amount of shade that this room receives?

1. Little Shade
2. Moderate Shade
3. Abundant Shade

Please select from the options above: 2

Air Conditioning Window Unit Cooling Capacity

Room Name: Kitchen
Room Area (in square feet): 300.0
Amount of Shade: Moderate
BTUs Per Hour needed: 10,000

Would you like to enter information for another room (Y/N)? N
