Write a java program:

Write a nested loop program creating an array list of three positions.  The first loop terminates with a sentinel value of which user is prompted for input to continue of quit.   Inside loop to enter in each position a prompted input of person's first name.  After the inside loop, edit the second array location making its value "Boston". Print the array's contents.

In databases, Normalization used to reduce redundancy and update anomalies from the tables. There are several Normal forms that are used in database 1NF, 2NF, BCNF etc.

The term functional dependency is very important in NF. Multivalued attributes, Atomicity property etc. plays important role in NF

Action Items

• You are requested to:
  • Submit 1NF and 2NF examples with explanation.
  • Discuss one of the following:
    • Discuss the need of Normal Forms.
• Discuss and explain why we need 2NF.
• Discuss the drawback of 1NF.
• Discuss Atomicity and multivalued attribute
• Discuss functional dependency
• All students have to participate at least twice in the discussions.

This program (in python) will display a set of authors and the number of novels written by each author in both a table and a histogram. You will ask the user for all of the information. Using what you learned about incremental development, use the following approach to create your program:

1. Prompt the user for the information about the table. First, ask for the title of this data set by prompting the user for a title for data. Output the title.
   
   Ex:

Enter a title for the data:
Number of Novels Authored
You entered: Number of Novels Authored

2. The table will have two columns; one for the authors and one for the number of novels. Prompt the user for the headers of two columns of the table. Output the column headers.
   
   Ex:

Enter the column 1 header:
Author name
You entered: Author name

Enter the column 2 header:
Number of novels
You entered: Number of novels

3. Prompt the user for data points. Data points must be in this format: string, int, representing the author and the number of novels written by the author. Store the information before the comma into a string variable and the information after the comma into an integer. The user will enter -1 when they have finished entering data points. Output the data points. Store the string components of the data points in a list of strings. Store the integer components of the data points in a list of integers.
   
   Ex:

Enter a data point (-1 to stop input):
Jane Austen, 6
Author: Jane Austen
Number of Novel(s): 6

4. Perform error checking for the data point entries as follows:

• If entry has no comma and is not -1
• Output: Error: No comma in string.

If the error occurs, output the appropriate error message and prompt again for a valid data point. You can assume that if a comma is present, then the data point is entered correctly.
Ex:

Enter a data point (-1 to stop input):
Ernest Hemingway 9
Error: No comma in string.

Enter a data point (-1 to stop input):
Ernest Hemingway, 9
Author: Ernest Hemingway
Number of Novel(s): 9

5. Output the information in a formatted table. The title is right justified with a minimum field width value of 33. Column 1 has a minimum field width value of 20. Column 2 has a minimum field width value of 23.
   
   Ex:

        Number of Novels Authored
Author name         |       Number of novels
--------------------------------------------
Jane Austen         |                      6
Charles Dickens     |                     20
Ernest Hemingway    |                      9
Jack Kerouac        |                     22
F. Scott Fitzgerald |                      8
Mary Shelley        |                      7
Charlotte Bronte    |                      5
Mark Twain          |                     11
Agatha Christie     |                     73
Ian Flemming        |                     14
J.K. Rowling        |                     14
Stephen King        |                     54
Oscar Wilde         |                      1

6. Output the information as a formatted histogram. Each name is right justified with a minimum field width value of 20.
   
   Ex:

         Jane Austen ******
     Charles Dickens ********************
    Ernest Hemingway *********
        Jack Kerouac **********************
 F. Scott Fitzgerald ********
        Mary Shelley *******
    Charlotte Bronte *****
          Mark Twain ***********
     Agatha Christie *************************************************************************
        Ian Flemming **************
        J.K. Rowling **************
        Stephen King ******************************************************
         Oscar Wilde *

(solve fast)

Latitude and Longitude are the two components used to exactly identify a specific spot on the Earth. Latitude provides the North/South direction and runs from 90 degrees north at the north poll to -90 degrees south at the south poll. The equator has a Latitude of zero.

Longitude provides the East/West direction and runs from the Prime Meridian that runs through Greenwich, England and has a Longitude of zero. Longitudes then run negatively to the west and positively to the east with the maximum Longitude being 180 degrees (or -180 degrees. They are the same Longitude.)

Usually Latitude and Longitude are usually depicted in degrees, minutes and second, but they can also be represented with just real numbers, which is how your class will need to be written. (FYI Lake Worth has a 26.61353 latitude and -80.057458)

Your assignment is to create a class called locCoordinates with the following properties and methods:

class locCoordinates

{

private:

            double latitude;

            double longitude;

            string location;

public:

            locCoordinates();

            bool set(double, double, string)

            bool setLatitude(double);

            bool setLongitude(double);

            void setLocation(string);

            double getLatitude();

            double getLongitude();

            string getLocation();

            void moveUpDown (double, string);

            void moveLeftRight (double, string);

            void move (double, double, string);

            void print();

}

And here are the specifics for this class.

The constructor should set the latitude and longitude to zero, and the location to "Prime Meridian at Equator). It should not accept any parameters (and should not call the set function).

The set function will take the two numbers entered (latitude then longitude) and ensure they are correct. If either of the numbers are not within the correct range, then the location should be set to "Error", the value of the invalid entry should be set to zero and the function return a false. If everything is good it returns a true.

setLatitude will change the current value of Latitude. It also needs to check to make sure that it is a good latitude. If not correct the function should set the Latitude to zero and return false otherwise return true. In either case, the Location should be changed to "Unknown".

setLongitude does what setLatitude does, only to the Longitude.

setLocation just updates the location string in the class.

The gets return the values in the properties.

moveUpDown will pass in a double that may be either negative or positive. This value needs to be adjusted for the number of total degrees in the latitude, and then the latitude adjusted by that amount. The location would then also be updated.

moveEastWest does just like moveUpDown, but does it for Longitude.

move takes both a change in Latitude and Longitude and applies them along with setting the new location. (If I were coding this, I would probably just call moveUpDown and moveEastWest to do the work!!)

print will print out:

            Latitude: 99.99999, Longitude: 999.99999 is at location: XXXXXX

You can implement this any way you want either by creating separate class header and implementation files, or by just putting everything in one big ole file with a main routine after the class definition. In the main routine, please set up a location with a bad input and show that a false is returned, then set one up with good input. Then use the move command to adjust the coordinates by an amount above 90 (or below -90) for latitude and above 180 (or below -180) for longitude. Then use the print function to print out the results.

In JAVA, write a number guessing game that randomly assigns a integer between one and twenty for the user to guess.

Write three methods to make this particular program work.

1. Have a method which generates a random number and returns the value to the main (stored as a variable)

2. Have a method which prompts the user for a guess. Return the guess to the main.

3. Evaluate the guess and the random "secret" number by parameters, and then have it evaluate if the guess is correct. RETURN A STRING to let the user know if the guess was correct, too high, or too low.

Use a nested loop in main. Ask the user if they would like to play again. Use an inner loop that continually calls the third method until the guess is correct.

Need Java Code and UML Design for the following program:

Use the Account class created above to simulate an ATM machine. Create five accounts in an array with id 0, 1, ..., 4, and initial balance $100. The system prompts the user to enter an id. If the id is entered incorrectly, ask the user to enter a correct id. Once an id is accepted, the main menu is displayed as shown in the sample run (see below). You can enter a choice 1 for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for exiting the main menu. Once you exit, the system will prompt for an id again. Thus, once the system starts, the ATM machine will not stop.

Sample run of the ATM machine is as follows: Enter an id to start transactions: 4

Main menu
1: check balance
2: withdraw
3: deposit
4: exit
Enter a choice: 1 The balance is 100.0

Main menu
1: check balance 2: withdraw

3: deposit
4: exit
Enter a choice: 2
Enter an amount to withdraw: 3

Main menu
1: check balance
2: withdraw
3: deposit
4: exit
Enter a choice: 1 The balance is 97.0

Main menu
1: check balance
2: withdraw
3: deposit
4: exit
Enter a choice: 3
Enter an amount to deposit: 10

Main menu
1: check balance
2: withdraw
3: deposit
4: exit
Enter a choice: 1 The balance is 107.0

Main menu
1: check balance 2: withdraw
3: deposit
4: exit
Enter a choice: 4

Enter an id to start transactions:
