This assignment will help you to get started with data types, variables, and arithmetic expressions. 1. If using NetBeans, create a new project. Use meaningful project name, for example, "hw2", "AreaAndPerimeter", or similar. 2. To begin, put a block comment at the beginning of your Java file. In the comment, include the assignment number, assignment title, program author, and the date the assignment is due. 3. Declare the AreaAnd PerimeterCalc class, then add a main method to it. 4. Display a welcoming message to the user. 5. Create a double variable named length and assign a hardcoded value to it. 6. Create a double variable named width and assign another hardcoded value to it. 7. Create a third variable named area. Assign a value to the area. It should be the result of the length multiplied by the width. 8. Create a fourth variable named perimeter. Use formula 2 * length + 2*width to compute the perimeter and store the result. 9. Use System.out object to display names of all variables follwed by the tab character ('\t'). followed by the value of that variable. Print each variable/value on separate line.

Question
Transcribed Image Text:This assignment will help you to get started with data types, variables, and arithmetic
expressions.
1. If using NetBeans, create a new project. Use meaningful project name, for example, "hw2",
"AreaAndPerimeter", or similar.
2. To begin, put a block comment at the beginning of your Java file. In the comment, include
the assignment number, assignment title, program author, and the date the assignment is due.
3. Declare the AreaAnd PerimeterCalc class, then add a main method to it.
4. Display a welcoming message to the user.
5. Create a double variable named length and assign a hardcoded value to it.
6. Create a double variable named width and assign another hardcoded value to it.
7. Create a third variable named area. Assign a value to the area. It should be the result of the
length multiplied by the width.
8. Create a fourth variable named perimeter. Use formula
2* length + 2 * width
to compute the perimeter and store the result.
9. Use System.out object to display names of all variables follwed by the tab character ('\t').
followed by the value of that variable. Print each variable/value on separate line.
![Coding Requirements
• As mentioned above, program should contain a block comment with the description of what
it does.
• Label the end of your class and the end of the main method with appropriate "ending"
comments:
public
public class AreaAndPerimeterApp
{
public static void main (String[] args)
{
// The code here is indented between the braces.
// ...
}//main
}//class AreaAndPerimeter App
• Align each opening and closing brace { } vertically as shown, so that the code looks neat, is
readable, and easy to understand.
This is often called "the coding style" by professional programmers. Successful styles exist
for many popular programming environments, including the style presented in our textbook.
Once adopted, the style must be followed by all programmers throughout the entire duration
of the project.
Indent all code between the beginning and ending braces. Indentation of all code blocks
allow program statements and comments to be easily observed.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1c50bd72-23cb-4139-953a-0cc18f92fc0e%2F5e54b307-6eb0-4b6e-be7f-7eb83fcb2db5%2Fv9nv7ii_processed.png&w=3840&q=75)
