Please do in java with code available for copy and with comments so I can follow along :)\

Develop a program that prints out the sum of each column of a two-dimensional array. The program defines method sumColumn() takes a two-dimensional array of integers and returns a single-dimensional array that stores the sum of columns of the passed array. The program main method prompts the user to enter a 3-by-4 array, prints out the array, and then calls method sumColumns(). Finally, it prints out the array retuned by method sumColumns(). Document your code, and organize and space the outputs properly as shown below. C++ students: instead of asking the user for input, you must read it from a file. See appendix for more information.

JAVA PROGRAM

The Florida Dental Association needs a simple program to record what teeth the members of Florida families have. Different Floridians have different numbers of different types of teeth (the program must use this simplified categorization of types of teeth):

• Biting teeth (the 'B' teeth)
• Chewing teeth (the 'C' teeth)
• Missing teeth (the 'M' teeth)

The program must record the teeth for one Florida family. When it starts the program asks how many people there are in the family (maximally 5), then for each family member gets their name, a string of tooth types for the uppers (maximally 10 teeth including missing teeth), and a string a tooth types for the lowers (maximally 10 teeth), e.g., the string "CMCBBBMCCM" would represent 10 teeth (of which three are missing). The names are recorded in an array of strings. The tooth information is recorded in a three dimensional array of characters, where each plane corresponds to a person, there are two rows for uppers and lowers, and each row has a column for each tooth. Once the information is recorded the program must offer a menu of four options:

1. Print the family's teeth record.
2. Extract a tooth (with a check that there is something there to remove).
3. Report the family's root canal indices, which are the roots of the quadratic equation Bx² + Cx - M, where B, C, and M are the family's numbers of those types of teeth.
4. Exit (with a smile)

The program must be reasonably idiot proof:

• Menu options must be accepted in upper and lower case.
• Tooth letters must be accepted in upper and lower case.
• All input must be checked to be in range, and if not the user must be asked to input again.
• You may assume that numeric input will be syntactically correct.

Here's what a sample run should look like (with the keyboard input shown in italics) ...

Exiting the Floridian Tooth Records :-)

Independent observations of the random X magnitude, which characterizes the deviation of the length of the part from the required technical conditions, are presented in the form of a simple statistical series. It is necessary to build a statistical (variation) series and histogram, to find estimates for mathematical expectation and variance.

Show your work.

Use the following time-series data to answer the given questions.

a. Develop forecasts for periods 5 through 10 using 4-month moving averages.

b. Develop forecasts for periods 5 through 10 using 4-month weighted moving averages. Weight the most recent month by a factor of 4, the previous month by 2, and the other months by 1.

c. Compute the errors of the forecasts in parts (a) and (b) and observe the differences in the errors forecast by the two different techniques.
