Question

1/Your team was asked to program a self-driving car that reaches its destination with minimum travel time.

Write an algorithm for this car to choose from two possible road trips. You will calculate the travel time of each trip based on the car current speed and the distance to the target destination. Assume that both distances and car speed are given.

2/

Write a complete Java program that do the following:

1. Declare String object and a variable to store your name and ID.
2. DisplayYour Name and Student ID.
3. Display Course Name, Code and CRN
4. Replace your first name with your mother/father name.
5. Display it in an uppercase letter.

Note:Your program output should look as shown below.

My Name: Ameera Asiri

My student ID: 123456789

My Course Name: Computer Programming

My Course Code: CS140

My Course CRN: 12345

AIYSHA ASIRI

Note: Include the screenshot of the program output as a part of your answer.

3/

Write a tester program to test the mobile class defined below.

Create the class named with your id (for example: Id12345678) with the main method.

1. Create two mobiles M1 and M2 using the first constructor.
2. Print the characteristics of M1 and M2.
3. Create one mobile M3 using the second constructor.
4. Change the id and brand of the mobile M3. Print the id of M3.

Your answer should include a screenshot of the output. Otherwise, you will be marked zero for this question.

public class Mobile {

private int id;

private String brand;

public Mobile() {

    id = 0;

    brand = "";

}

public Mobile(int n, String name) {

    id = n;

    brand = name;

}

public void setBrand(String w) {

    brand = w;

}

public void setId(int w) {

    id = w;

}

Public int getId() {

return id;

}

public String getBrand() {

return brand;

}

}

4/

Write a method named raiseSalary that accepts two integers as an argument and return its sum multiplied by 15%. Write a tester program to test the method. The class name should be your ID (for example: Id12345678).

Your answer should include a screenshot of the output. Otherwise, you will be marked zero for this question.

Answer :

import java.util.Scanner;

public class selfDrivingCar {

  
   double minimumTravelTime(double timeTakenByFirstRoadTrip, double timeTakenBySecondRoadTrip) {
       return Math.min(timeTakenByFirstRoadTrip, timeTakenBySecondRoadTrip);
   }

   double timeTakenInRoadTrip(double speed, double distance) {
       return distance / speed;
   }

   public static void main(String args[]) {
       selfDrivingCar selfDrivingCar = new selfDrivingCar();
       Scanner scanner = new Scanner(System.in);
       System.out.println("Enter speed and distance in first road trip:");
       double timeTakenInFirstRoadTrip = selfDrivingCar.timeTakenInRoadTrip(scanner.nextDouble(), scanner.nextDouble());
       System.out.println("Enter speed and distance in second road trip:");
       double timeTakenInSecondRoadTrip = selfDrivingCar.timeTakenInRoadTrip(scanner.nextDouble(), scanner.nextDouble());
       scanner.close();
       double minimumTravelTime = selfDrivingCar.minimumTravelTime(timeTakenInFirstRoadTrip, timeTakenInSecondRoadTrip);
       System.out.println("Minimum travel time: "+minimumTravelTime);
   }

}

Answer :  Please change class name as per your Id.

import java.util.Scanner;

public class Id12345677 {
  
   public static void main(String args[]) {
       Scanner scanner = new Scanner(System.in);
       System.out.println("Enter your firstName,lastName, studentId,courseName,courseId,courseCRN,fatherOrMotherFirstName: ");
       String firstName = scanner.nextLine();
       String lastName = scanner.nextLine();
       String studentId = scanner.nextLine();
       String courseName = scanner.nextLine();
       String courseId = scanner.nextLine();
       String courseCRN = scanner.nextLine();
       String fatherOrMotherFirstName = scanner.nextLine();      
       System.out.println("My Name: "+firstName+ " "+lastName);
       System.out.println("My student ID: "+studentId);
       System.out.println("My Course Name: "+courseName);
       System.out.println("My Course Code: "+courseId);
       System.out.println("My Course CRN: "+courseCRN);
       System.out.println(fatherOrMotherFirstName.toUpperCase()+" "+lastName.toUpperCase());
      
   }

}

Answer: Please change class name as per your Id.

public class Id12345679 {

   public static void main(String args[]) {

       Mobile M1 = new Mobile();
       System.out.println("Characteristics of M1 :");
       System.out.println("Id :"+ M1.getId());
       System.out.println("Brand :"+ M1.getBrand());
       Mobile M2 = new Mobile();
       System.out.println("Characteristics of M2 :");
       System.out.println("Id :"+ M2.getId());
       System.out.println("Brand :"+ M2.getBrand());
       Mobile M3 = new Mobile(1, "M3");
       System.out.println("Characteristics of M3 :");
       System.out.println("Id :"+ M3.getId());
       System.out.println("Brand :"+ M3.getBrand());
      
   }

Answer : Please change class name as per your Id.

import java.util.Scanner;

public class Id12345678 {
  
  
   double raiseSalary (int firstArgument,int secondArgument) {
      
       return ((firstArgument+secondArgument)*0.15);
      
   }
  
   public static void main(String args[]) {
      
       Scanner scanner = new Scanner(System.in);
       System.out.println("Enter two arguments:");      
       int firstArgument = scanner.nextInt();
       int secondArgument = scanner.nextInt();
       Id12345678 id12345678 = new Id12345678();
       double raisedSalary = id12345678.raiseSalary(firstArgument, secondArgument);
       System.out.println("Raised Salary : "+raisedSalary );
   }

}
