1. An airplane model can be described (highly oversimplified) by the following attributes • model: string • emptyweight: double • number of seats: int • fuel Consumption: double a) Define a class AirplaneModel with the attributes defined above. b) Your class should contain the following member functions: • A default constructor that initializes the class’s attributes. • A constructor that sets the attributes. • string getName() to get the model’s name • double getEmptyWeight() to get the model’s empty weight...
Create 3 user-defined methods called add(). 1 accepts a single integer array parameter; this method should loop the array adding the values and return the summation (use 4, 1, 4, 6, 10, 15, 32, 79, 18 as the values in the array) 1 accepts 2 integer parameters; this method should add them and return the value 1 accepts 3 integer parameters; this method should add them all and return the value In main, define the parameters above (you may use...
python code? 1. Create a class called Person that has 4 attributes, the name, the age, the weight and the height [5 points] 2. Write 3 methods for this class with the following specifications. a. A constructor for the class which initializes the attributes [2.5 points] b. Displays information about the Person (attributes) [2.5 points] c. Takes a parameter Xage and returns true if the age of the person is older than Xage, false otherwise [5 points] 3. Create another...
Write an SQL statement to develop a new database called ACCOUNT with the following attributes: 1) Account_Number, 2) Customer_ID, 3) Account_Type, 4) Balance and 5) Opening_date. Note that you need to determine data types for the attributes.
Problem #1 Write a user-defined function called mysecant. (Not an an please!) The purpose of the function is: Given two points, compute the line between them and so where the corresponding y3-0. If there is no solution, Hint: The governing equations are: (y3-y1)-(y2-y1) / (x2-x1) * (x3-x1) if y3-0, then solve for x3, and so, x3-x1-y1 * (x2-x1) / (y2-y Inputs: x1, y1, x2, y2 Output: x3
Consider the interface Predicate defined as follows. interface Predicate { boolean eval(int j); } Recall that you can check if an integer “i” is even by using the expression “i%2 == 0”. Write a class IsEven that determines whether a number is even: class IsEven implements Predicate { public boolean eval(int j) { } } For example, the following code Predicate p = new IsEven(); if ( p.eval(2)) { System.out.println("2 is even"); } if (! p.eval(3)) { System.out.println("3 is not...
Python 3> Make a class called BMW: Parameterized constructor with three instance variables (attributes): Hint: def __init__(self, make, model, year) Methods in BMW parent class (can leave as method stubs for now): startEngine() -must print "The engine is now on." stopEngine() -must print "The engine is now off." Make another class called ThreeSeries -Must inherit BMW Hint: class ThreeSeries(BMW): -Also passes the three attributes of the parent class and invoke parent Hint: BMW.__init__(self, cruiseControlEnabled, make, model, year) -Constructor must have...
Please explain each line of code, all code will be in Java. Thank you JKL Restaurant maintains a members’ club for its customers. There are three levels of membership: (1) Basic, (2) Silver, and (3) Gold. A certain member has to be exactly a Basic, Silver, or Gold member at any point in time. Whenever a member spends money at JKL, he/she gets points and as these points are accumulated, one can redeem one or more $20 dining certificates. Each Gold member can...
1. What will be the value of x after the following code is executed? int x = 10, y = 20; while (y < 100) { x += y; } A. 90 B. 110 C. 210 D. This is an infinite loop 2. If a superclass has constructor(s): A. then its subclass must initialize the superclass fields (attributes). B. then its subclass must call one of the constructors that the superclass does have. C. then its subclass does not inherit...
MATLAB Problem
HW7P2 (20 points) (5 pts) Write a user-defined MATLAB function called HW7P2_fn for the following math function 3 o-0.47x The input to the function is x and the output is y. Write the function such that x can be an array (use element-by-element operations) (15 pts) Use the function in (a) the command window to calculate y(-2) and y(5) (b) a script file HW7P2.m to determine y(x) for 0.001 Sx S 10 with 1000 points. Hint: Use the...
