//Not sure what additional information you are asking for? Itasks for me to copy a code for Project7 which I have provided acopy of. I have also provide copies of the codes for the methodsneeded to be included. I also provided Project6b which is what Ineeds to be used as part of the code. Please Advise and thank youfor your assistance. Please help with the followig I will supply copy ofProject6b.java file and copy of the code need for Project 7 tocomplete 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 androds) where the weight of the steel is calculated by multiplyingthe volume of the shape in cubic feet by the weight of a cubic footof steel (489lbs.). Now that the Weight program is extensible with our transition toobjects in 6b, we can add shapes that cannot be calculated usingtheir volume. There are several shapes (angles, I-beams, columns)that require a table lookup to get the shape’s weight per footwhich can be multiplied by the item’s length to get the item’sweight. To support adding angles to our shipments, we are going to haveto support the angle input which is of the form: L angle-size angle-thickness length Where thickness is expressed as a fraction and length isconsistent 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, 2×2, 3×2, or 4×3. For the purposes of this Project,we are only supporting two sizes: • 2×2 1/4 • 3×3 ¼ User Story In addition to plates and rods, allow the user to enter an angleshape as shown below. For example: Enter shape and dimensions: L 2×2 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 andselecting Copy…. 2. In Project7 set TESTIT to true so that test() will run whenyou run Project7. 3. Copy Project7AngleTests.java into the test() method inyourProject7.
COPY OF THIS CODE: // Put this at the end of test() *but before* the return errors; statement. expected_result = 3.19; result = Angle.weightPerFoot(“2×2”, .25 / 12); if (result == expected_result) { System.out.println(“PASSED: Angle.weightPerFoot(“2×2″, .25)”); } else { System.out.println(“FAILED: Angle.weightPerFoot(“2×2″, .25) returned ” + result + ” and not ” + expected_result); ++errors; } item = shipment.addItem(1, “L 2×2 1/4 5-7”); expected_result = 17.81083333333333; result = item.weight(); if (result == expected_result) { System.out.println(“PASSED: Weight of L 2×2 1/4 5-7”); } else { System.out.println(“FAILED: Weight of L 2×2 1/4 5-7 is ” + result + ” and not ” + expected_result); ++errors; } 4. Build and note that the compilation errors are because of themissing Angle object. 5. Create the LookupShape object by copying the CalcShapeobject. a. Change _area element with _weight_per_foot. b. Change area setter method with weightPerFoot and make thenecessary changes to the weight calculation from area * length toweight-per-foot * length. 6. Copy Project7Angle.java from examples into your Project7.javafile. Put the new Angle class in a location in the file that makessense. 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 “2×2”. 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 Angleclass. 8. Now run the unit tests. There are two new tests: a. Angle.weightPerFoot – This should pass. b. Weight of L 2×2 1/4 5-7 – should take an error because 2×2 isnot handled as a dimension. 9. Copy Project7ShipmentAddItem.java over the current Shipmentclass’ addItem to handle the 2×2 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 fourtests below making sure you end the items and see the totalshipment output. Checklist Use the following as guidance for getting a 10 on thisproject: • LookupShape class implemented for weight per foot (as opposedto area). (2 point) • Angle class implemented to calculate weights of angles intable (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 doesn’t end theprogram or shipment, outputs an error, and prompts again foranother shape.
