//Not sure what additional information you are asking for? It asks for me to copy a code for Project7 which I have provided a copy of. I have also provide copies of the codes for the methods needed to be included. I also provided Project6b which is what I needs to be used as part of the code. Please Advise and thank you for your assistance.

Please help with the followig I will supply copy of Project6b.java file and copy of the code need for Project 7 to complete and will identify them:

Goals

More test-driven development.

Learn how to create inherited classes.

Learn how to use multidimensional arrays.

Problem

The Weight program is limited to those steel shapes (plates and rods) where the weight of the steel is calculated by multiplying the volume of the shape in cubic feet by the weight of a cubic foot of steel (489lbs.).

Now that the Weight program is extensible with our transition to objects in 6b, we can add shapes that cannot be calculated using their volume. There are several shapes (angles, I-beams, columns) that require a table lookup to get the shapes weight per foot which can be multiplied by the items length to get the items weight.

To support adding angles to our shipments, we are going to have to support the angle input which is of the form:

L angle-size angle-thickness length

Where thickness is expressed as a fraction and length is consistent with the length dimension we have used in Project 6b (e.g. feet-inches). The angle-size input is of the form:

leg-in-inchesxleg-in-inches

For example, 2x2, 3x2, or 4x3. For the purposes of this Project, we are only supporting two sizes:

2x2 1/4

3x3

User Story

In addition to plates and rods, allow the user to enter an angle shape as shown below. For example:

Enter shape and dimensions: L 2x2 1/4 3-4

Angle weighs 10.633333333333333

Tasks

1. Copy your Project6b project (only after you finish Project6b) to Project7 by right-mouse clicking on Project6b NetBeans and selecting Copy....

2. In Project7 set TESTIT to true so that test() will run when you run Project7.

3. Copy Project7AngleTests.java into the test() method in yourProject7.

COPY OF THIS CODE:

 // Put this at the end of test() *but before* the return errors; statement. expected_result = 3.19; result = Angle.weightPerFoot("2x2", .25 / 12); if (result == expected_result) { System.out.println("PASSED: Angle.weightPerFoot(\"2x2\", .25)"); } else { System.out.println("FAILED: Angle.weightPerFoot(\"2x2\", .25) returned " + result + " and not " + expected_result); ++errors; } item = shipment.addItem(1, "L 2x2 1/4 5-7"); expected_result = 17.81083333333333; result = item.weight(); if (result == expected_result) { System.out.println("PASSED: Weight of L 2x2 1/4 5-7"); } else { System.out.println("FAILED: Weight of L 2x2 1/4 5-7 is " + result + " and not " + expected_result); ++errors; }

4. Build and note that the compilation errors are because of the missing Angle object.

5. Create the LookupShape object by copying the CalcShape object.

a. Change _area element with _weight_per_foot.

b. Change area setter method with weightPerFoot and make the necessary changes to the weight calculation from area * length to weight-per-foot * length.

6. Copy Project7Angle.java from examples into your Project7.java file. Put the new Angle class in a location in the file that makes sense. Hint: Near the Plate and Rod classes.

COPY OF THIS CODE:

class Angle extends LookupShape { private static double[][] _table = {{2, 2, .25/12, 3.19}, {3, 3, .25/12, 4.9}}; public static double weightPerFoot(String angleSize, double thick) { double wpf = 0.0; // The parameter angleSize is a string like "2x2". Convert it into two // doubles for the first side and second side. You are going to use the // to look up the weight per foot. boolean found = false; // Loop through each row in the table to see if there is a row that matches the two sides // and thickness. The first two elements of a row are the two sides. The third element // in the row is the thickness (in feet) and the fourth is the weight to be returned from // this function if there is a match. When you do find a match, do the following: // 1. Set wpf to the fourth element // 2. Set found to true // 3. Break out of the loop because we are done. // Put lookup loop here. if (!found) { throw new IllegalArgumentException("Angle of " + angleSize + " x " + thick + " not found"); } return wpf; } Angle(String angleSize, double thick, double length) { double wpf = weightPerFoot(angleSize, thick); super.weightPerFoot(wpf); super.length(length); } }

7. Write the code called out in the comments within the Angle class.

8. Now run the unit tests. There are two new tests:

a. Angle.weightPerFoot This should pass.

b. Weight of L 2x2 1/4 5-7 should take an error because 2x2 is not handled as a dimension.

9. Copy Project7ShipmentAddItem.java over the current Shipment class addItem to handle the 2x2 dimension.

COPY OF THIS CODE:

 public SteelShape addItem(int quantity, String description) { String[] desc_values = description.split(" "); String angle_size = ""; double[] values = new double[desc_values.length - 1]; String shape_letter = desc_values[0]; int values_index = 0; for (int i = 1; i < desc_values.length; i++) { if (desc_values[i].indexOf("x") > 0) { angle_size = desc_values[i]; } else { values[values_index] = getValueInFeet(desc_values[i]); ++values_index; } } SteelShape shape = null; if (shape_letter.equals("P")) { if (values.length != 3) { throw new IllegalArgumentException("Plate needs three dimensions"); } shape = new Plate(values[0], values[1], values[2]); } else if (shape_letter.equals("R")) { if (values.length != 2) { throw new IllegalArgumentException("Rod needs two dimensions"); } shape = new Rod(values[0], values[1]); } else if (shape_letter.equals("L")) { if (values.length != 3) { throw new IllegalArgumentException("Angle needs three dimensions"); } shape = new Angle(angle_size, values[0], values[1]); } else { throw new IllegalArgumentException("shape letter '" + shape_letter + "' not recognized"); } _weight += quantity * shape.weight(); return shape; }

10. Run the unit tests again. All should pass.

11. Set TESTIT to false and test interactively with the four tests below making sure you end the items and see the total shipment output.

Checklist

Use the following as guidance for getting a 10 on this project:

LookupShape class implemented for weight per foot (as opposed to area). (2 point)

Angle class implemented to calculate weights of angles in table (pass unit tests). (6 points)

Weight program successfully adds Angle items to shipments (pass test data below). (1 point)

Enter in a bad angle size and make sure it doesnt end the program or shipment, outputs an error, and prompts again for another shape. (1 point)

Shape Size Thick. orDiameter Width Length Weight

P 1/4 5-6 2-3 126.07

R 3/4 5-7 8.376302

L 2x2 1/4 3-4 10.63333
