This task is about classes and objects, and is solved in Python 3.

We will look at two different ways to represent a succession of monarchs, e.g. the series of Norwegian kings from Haakon VII to Harald V, and print it out like this:

King Haakon VII of Norway, accession: 1905

King Olav V of Norway, accession: 1957

King Harald V of Norway, accession: 1991

>>>

Make a class Monarch with three attributes: the name of the monarch, the nation and year of accession. The class should have a method write () which prints out the information on a line like in the example. It should also have the method _init_ (…), so that you can create a Monarch instance by name, nation and year of accession as arguments. Example:

haakon = Monarch("Norway","King Haakon VII",1905)

Here, the variable haakon will be assigned to the Monarch object for King Haakon VII. Now the series of kings can be represented in a variable series of kings, that contains a list of the three monarchs, in the right order. Finally, the program will print the series of kings as shown above.

Required Tasks:

  1. In Eclipse, create a Java Project as CS-176L-Assign5.
  2. Create 3 Java Classes each in its own file Student.java, StudentList.java, and Assign5Test.java.
  3. Copy your code from Assignment 4 into the Student.java and StudentList.java Classes. Assign5Test.java should contain the main method.
  4. Modify StudentList.java to use an ArrayList instead of an array. You can find the basics of ArrayList here: https://www.w3schools.com/java/java_arraylist.asp
  5. In StudentList.java, create two new public methods:
    1. The addStudent method should have one parameter of type Student and should add the given Student to the StudentList.
    2. The removeStudent method should have one parameter of type String. The String is the email of the student to be removed from the StudentList.
  6. In Assign5Test.java do the following:
    1. Create a new StudentList containing 3 students.
    2. Print the info of all the Students in the StudentList using the getAllStudentInfo method.
    3. Remove one Student from the StudentList using the removeStudent method.
    4. Add two new Students to the StudentList using the addStudent method.
    5. Print the info of all the Students in the StudentList using the getAllStudentInfo method. Notice that one Student was removed and two were added.
  7. Code must compile and run without warnings or errors.
  8. Final output should look something like the following:

6) A solution of sodium chloride (molecular weight 58.5) is electrolyzed and it is found that a
current of 1 A liberates 1.3 x 10-3 kg of chlorine (atomic weight 35.5) in one hour. Sodium
chloride crystals of density 2.17 x 103 kg/m3 are analyzed by x rays and the unit cell parameter is
found to be 5.6 x 10-10 m. From these data calculate the charge on a monovalent ion.


7) In a Milikan oil-drop experiment, a certain droplet was found to fall freely in air at a steady rate
of 1.15 x 10-4 m/sec. between horizontal plates 3 mm apart. When an electrical potential
difference of 400 V was applied between the plates, the droplet rose steadily at 1.2 x 10-5 m/sec;
while at 300 V, the droplet fell steadily at 1.8 x 10-5 m/sec. Find the magnitude of the charge on
the drop, given that the viscosity of the air is 1.8 x 10-5 mks units, and the density of the oil used
was 900 kg/m3.


8) In an experiment to determine e/m for electrons by J. J. Thomson’s method, the particles were
deflected by a uniform electrostatic field of 50000 V/m applied between plates 0.05 m long. The
deflection produced on a screen placed 0.3 m away from the center of the plates was 0.05 m.
This deflection was exactly canceled by applying a magnetic field of 0.001 Tesla coextensive with
the electric field. Find the speed of the electrons, their specific charge, and the accelerating
voltage.

Checking Input File for correct line format.

So for my C++ assignment, my professor says we need to validate the Input File, if there are white lines and spaces, in which it will ignore them, separated by a comma, and that all data items are there. This will be used in a program where i will store these into an Array, and display them in First name, Last name, and Number of Votes vertical columned categories.

This is a sample of the txt file. My question is, What do i use to be able to take only the names and number and place them into an array. Please explain what each line is doing, even it is not completely obvious. I am a complete beginner.

F=Michael,L=John,V=3342

F=Danny,L=Red,V=2003

F=Hillary,L=Clinton, V=1588

F=Albert,L=Lee,V=5332

F=Steven,L=JohnV=4429

Correct line for the reference: F=John,L=Smith,V=3342

The line errors that your program needs to detect, are as follows:

incorrect token / separator, example in line 5: F=Steven,L=JohnV=4429

(comma missing) – lines with this error need to be ignored

space in token, example in line 3: F=Hillary,X=Clinton, V=1622

lines with this error need to be read, error fixed, data included in your dataset

empty line, example in line 6 – empty lines need to be ignored

This is the sample of the getline code we are suppose to use.

void readFile(Candidate candidates[]) {

string line;

ifstream infile;

infile.open("elections.txt");

while (!infile.eof()) {

getline(infile,line);

// your code here

}

infile.close();

}
