Implement all the classes using Java programming language from the given UML Class diagram. Note: This problem requires you to submit just two classes: Customer.java, Account.java. Do NOT include "public static void main()" method inside all of these classes. Graders will be testing your classes, using the unit-testing framework JUnit 4. Customer - ID:int -name:String -gender:char 'm' or 'f' +Customer(ID:int,name:String, discount:int) +getID():int +getName ():String +getGender ():char +toString():String "name (ID)" The Customer class models, customer design as shown in the class diagram.

Define Point with attributes: x, y. Encapsulate Point (Declare the attributes as private and define the setters and getters) Define the constructors (default, with parameters). Override toString and equals
dict1 = {(1,1,1):"red", (2,1,-1):"green", (0,-1,1):"red", (0,0,-2):"blue"}In this case, there are 2 red points, and their centroid is at ( (1+0)/2, (1-1)/2, (1+1)/2 ) = (0.5, 0, 1)Considering that in this example there is only one green and one blue point, they are representing the respective color's centroid. Hence, your function should return the following dictionary:{"red":(0.5,0.0,1.0), "green":(2.0,1.0,-1.0), "blue":(0.0,0.0,-2.0)}

Write the code for the following UML diagram. Vehicle color:Sting -speeddouble -fuel:double *state: String +input):vold +addFuel): double moving0void +stop(:void +display0:void 1. Input(): Ask user to provide values for color and fuel. Default values for speed is "0" and state is "stopped" 2. addFuel0: Ask user to provide value for fuel to add. Add that value in fuel (attribute) and return value of total fuel. 3. moving0: Ask user to provide the speed of vehicle and fuel consumption. Set the value of speed and reduce the fuel (attribute) according to fuel consumption. And also set the state to "Moving". 4. stop(): This method will display that "Vehicle is stopped" and sets the value of speed to "0" and state to "Stopped" 5. display): This method will display the attributes value to output like: "Vehicle is stopped. It has red color. It's speed is 0.0 and fuel is 2.5 Liter"
