Chapter 9, Problem 6E
Good boundary testing also involves testing values that lie just beyond the valid range of data. Test 0 and 6 as rating values. In both cases, the comment should be rejected (addComment should return false, and the comment should not be added to the comment list.

Create functional tests where arguments are given, use a parameterized test.
testSimpleInit(size): the first constructor works as expected.
getTiles shows suitable values.
The edges of the board (the smallest and biggest conceivable values) are accessible and contain the values that they have to (BASE_TILE_SCORE).
testCustomInit(x, y, expected): the second constructor works as expected.
On positions where values smaller than three were passed, the board contains the value BASE_TILE_SCORE.
If you pass an array to the constructor and later modify a value in it, the respective tile retains the originally passed value.
If you modify an element in the return value of getTiles(), and get the value of the respective tile again, this newly received content has to be the originally set value.
testMoves(): take four or five steps and check that the board’s contents are changed just right.
Include a step that tries to move to the x coordinate Integer.MIN_VALUE and another one that moves to…
use this code template to help you continue:
private boolean included
Indicates whether the item should be taken or not
public Item(String name, double weight, int value)
Initializes the Item’s fields to the values that are passed in; the included Field is initialized to false
public Item(Item other)
Initializes this item’s fields to the be the same as the other item’s
public void setIncluded(boolean included)
Setter for the item’s included field (you don’t need setters for the other fields)
Given code:
public class Item {
private final String name;
private final double weight;
private final int value;
public Item(String name, double weight, int value) {
this.name = name;
this.weight = weight;
this.value = value;
}
static int max(int a, int b)
{
if(a > b)
return a;
return b;
}
// function to print the items which are taken
static void printSelection(int W, Item[] items, int…
The final keyword should be used on any instance field, parameter, or local variable that will not or should not change after initialization. This protects against inadvertently changing the value elsewhere in the code.

Follow each step to gradually complete all instance methods. Note: This program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress. The main program includes basic calls to the instance methods. Add statements in the main program as instance methods are completed to support development mode testing. **Step 0: Complete the constructor to initialize the model and miles per gallon (MPG) with the values of the parameters. Initialize the odometer to five miles and the tank to be full of gas. By default, the model is initialized to "Old Clunker", and MPG is initialized to 24.0.

Given the classes in the image as well as an image of the screen which will call the function, modify the given code so that it loops through the items again, this time as it loops through you are to insert the data into the salesdetails table, note that the SalesNumber from the AUTO-INCREMENT field from above is to be inserted here with each record being placed into the salesdetails table. Finally, as you loop through the items the product table must be update because as products are sold the onhand field in the products table must be updated. When multiple tables are to be updated with related data, you should wrap it into a DMBS transaction. The schema for the database is also depicted. public class PosDAO { private Connection connection; public PosDAO(Connection connection) { this.connection = connection; } public void…arrow_forward
- Rules: Corner cases. By convention, the row and column indices are integers between 0 and n − 1, where (0, 0) is the upper-left site. Throw an IllegalArgumentException if any argument to open(), isOpen(), or isFull() is outside its prescribed range. Throw an IllegalArgumentException in the constructor if n ≤ 0. Unit testing. Your main() method must call each public constructor and method directly and help verify that they work as prescribed (e.g., by printing results to standard output). Performance requirements. The constructor must take Θ(n^2) time; all instance methods must take Θ(1)Θ(1) time plus Θ(1)Θ(1) calls to union() and find().arrow_forwardModified Circle class and test file: Add a new attribute for color (or any other new attribute) Add get/set methods for this new instance variable, including data validation in set method (assuming background is black, i.e. circle color can't be black, reset to any non-black color if black is entered ). Add a new constructor to pass the color attribute as an argument. Add an instance method to display all properties of a Circle object. Create 2 objects using different constructors in test file, with invalid data. Use this test java file test java file: class CircleTest{ public static void main(String[] args){ int num = 10; Circle c1 = new Circle(0.001); Circle c2 = new Circle("black", -9); c1.display(); c2.display(); c1.setRadius( -1); c1.setColor("black"); c1.display(); }}arrow_forwardUse this code template to continue the code: public Item(String name, double weight, int value) Initializes the Item’s =ields to the values that are passed in; the included =ield is initialized to false public Item(Item other) Initializes this item’s fields to the be the same as the other item’s public double getWeight() public int getValue() public boolean isIncluded() Getter for the item’s fields (you don’t need a getter for the name) Given code: public class Item { private final String name; private final double weight; private final int value; private boolean included; public Item(String name, double weight, int value) { this.name = name; this.weight = weight; this.value = value; } public Item(Item item){ name = item.name; weight = item.weight; value = item.value; } public void…arrow_forward
- in Jave create two methods work(), and interwork() with the follow instructions: You may assume that the work() method is passed a List that does not contain any null elements. (Note: The List may contain missing elements.) The work() method must not have any side effects. That is, it must not change the parameters that it is passed in any way and it must not change any attributes in any way. The work() method must return the weighted average of the elements in the List it is passed. The label of the result must equal the parameter named rl. The data parameter contains the values to use in the calculation. If an element of data is missing (i.e., has a value attribute that is null) then that element must be ignored in the calculation. The weights attribute contains the weights to use in the calculation. If the weights attribute is null then all weights used in the calculation must be 1.
