A loop that evaluates its test expression before each repetition is a(n) __________ loop.
JAVA
Project 2-3 Rectangle Calculator
Create an application that calculates the area and perimeter of a rectangle. Then using a loop, ask the user if they want to continue. If yes then repeat the input, processing, and output. If no then end the program.
Console
Welcome to the Area and Perimeter Calculator
Enter length: 100
Enter width: 200
Area: 20000.0
Perimeter: 600.0
Continue? (y/n): y
Specifications
The formulas for calculating area and perimeter are:
area = width * lengthperimeter = 2 * width + 2 * length
The application should accept decimal entries like 10.5 and 20.65.
Assume that the user will enter valid numeric data for the length and width.
The application should continue only if the user enters “y” or “Y” to continue.
Input:
Print the header "Welcome to the Area and Perimeter Calculator"
Ask the user to enter a length
Ask the user to enter a width
Processing:
Save the length and width in variables
Calculate the area and save the results in a variable…

- AdderAA.java This program will allow the user to select how many numbers they’d like to add together, and then enter those numbers to be totaled. The program should run in a continuous loop unless the user enters zero at the menu (in this case the program should end). A negative menu answer should give an “invalid response.” Your code should catch input mismatches. There will be multiple loops and probably an if/else structure required to accomplish this. You cannot use a break statement or any other non-logical way such as System.exit to exit a loop. This will result in a loss of major points. The example below is one continuous run of the program. Your program should run the test case exactly as it appears below, and should work on any other case in general. Output Example This program will add numbers together.
