Please write on paper

Write one Java application based on the following directions and algorithms. Make sure the results from each of the numbered items is separate and easy to read/understand.

1.Create an array that will hold 4 string values. Write three separate statements to store your favorite color, your favorite song, and your favorite restaurant in the array elements. I do not want you to use a loop in this logic; use hard-coded index values instead. Print *ALL FOUR* of the values of the array using individual index values. What is stored in the element you did not fill?

2.Create an array that will hold 5 string values. Use a for loop to prompt the user to enter their 5 favorite movies and store each one in a separate element of the array. Print the values of the array using a For-Each loop.

3.Create an array to hold 7 doubles. Use any looping structure you want to prompt the user to enter a value and store it in the array. In a separate loop, compute the sum of the values. In a third, separate loop, display the array values in reverse order. Also display the sum.

4.Create an array that will hold 3 integers. Without prompting the user for input or using a loop, fill that array with the values 23, 0, and -5. Write decision logic to determine whether the values in each array element is negative, positive, or equal to zero. Make the decision logic loop 3 times, since we want to test 3 different values.

I would like to see a java language example using classes customer() and animal() which get user input and return the information to class database().

class customer() should return user input for firstName, lastName, address, phoneNum, customerNum.

class animal() should return information for animalName, animalType, gender, animalLocation.

7.15 Translate the following string method invocations to functions calls in namespace str:

(Python)

(a) ' error'. upper( )

(b) ' 2, 3, 4, 5'. split(',' )

(c) ' mississippi'.count('i' )

(d) ' bell'.replace('e' , 'a' )

(e) ' '. format(1, 2, 3)

1-Create a one-dimensional array of 99 double values. Then, use a for loop to add a random number from 0 to 100 to each element in the array. To do that, use the random method of the Math class to get a double value between 0.0 and 1.0 and multiply it by 100

like this

Math.random() * 100

2-Use an enhanced for loop to sum the values in the array. Then, calculate the average value and print that value on the console like this

Average: 50.9526671843517

3-Use the sort method of the Arrays class to sort the values in the array, and print the median value (the 50th value) on the console

like this

Median:    52.18369291650803
-Print the 9th value of the array on the console and every 9th value after that.

like this

position:    9         8.927702403161032

position:    18       14.0531287498060076

...

position:   99      22.471670293184822

6. 1100₂ – 0001₂ =
7. 1011₂ – 1101₂ =
8. 1110₂ – 0010₂ =

This is JAVA. Must write a short description of this program, usually a sentence or two will be sufficient. All the classes, methods and data fields should be clearly documented (commented).

Write a program that will predict the size of a population of organisms. The program should ask for the starting number of organisms, their average daily population increase (as a percentage), and the number of days they will multiply. For example, a population might begin with two organisms, have an average daily increase of 50 percent (=0.5), and will be allowed to multiply for seven days. The program should use a loop to display the size of the population for each day.

Input Validation: Do not accept a number less than 2 for the starting size of the population. Do not accept a negative number for average daily population increase. Do not accept a number less than 1 for the number of days they will multiply.

Example Run

Enter the starting number organisms: 2
Enter the daily increase: 0.5
Enter the number of days the organisms will multiply: 7
Day Organisms
-----------------------------
1 2.0
2 3.0
3 4.5
4 6.75
5 10.125
6 15.1875
7 22.78125

PHYTON QUESTIONS

Your assignment is to write the following magic methods for the Date class.

1. __eq__ returns True if two Date objects have the same month, day, and year.

2. __add__ is passed an int as a parameter, and adds that number of days to the Date. It is nondestructive. For example:

>>> d = Date(1,31,2017)

>>> d + 5 Date(2,5,2017)

>>> d Date(1,31,2017)

3. __getitem__ is passed either an int between 0 and 2, or a str ‘month’, ‘day’, or ‘year’. It returns the appropriate instance variable from the Date object, or raises an exception otherwise. For example:

>>> d = Date(2,1,2017)

>>> d[0] 2

>>> d[2] 2017

>>> d[‘day’] 1

>>> d[4] # should raise an IndexError

4. __setitem__ is passed an index (as described in problem 4) and an integer, and sets the month, day, or year of the Date object to be that integer. If the index is not of the correct type or value, then an exception is raised. For example:

>>> d = Date(2,1,2017)

>>> d[0] = 5

>>> d Date(5,1,2017)

>>> d[‘year’] = 2020

>>> d Date(5,1,2020)

>>> d[‘moth’] = 31 # should raise an IndexError

5. __radd__ is passed an integer, and modifies the Date object to be the specified number of days into the future. It is destructive. For example:

>>> d = Date(2,1,2017)

>>> d += 28

>>> d Date(3,1,2017)

in Java:

A point in the x - y plane is represented by its x-coordinate and y-coordinate. Design a class, pointType, that can store and process a point in the x - y plane. You should then perform operations on a point, such as :

– Print the point

– Set the x-coordinate

– Set the y-coordinate

– Get the x-coordinate

– Get the y-coordinate

– Add() : add two points

– Sub(): subtract two points

– Mul(): multiply two points

– Div(): divide one point from the other

– Ass(): assign one point to the other

– Equ(): check if two points are equal

– LessThan(): check if one point is less than the other • Note: R = √ X2 − Y2

– The default constructor

– The second constructor

– The copy constructor 2.

## Design a class pointTypeTest to test the design of pointType.

Thank you in advance!

7) Given a binary search tree, insert a new node with specific data such that the binary tree after the insertion is also a binary search tree.

8) Given a binary search tree, delete a node with a specific data value such that the binary tree after the deletion is also a binary search tree.

13. For a computer, you are given the following parameters:

Average memory access time in the absence of paging (i.e., a single physical memory access time, which is computed by considering the main memory access time and the CPU’s L1 cache): 80 ns

TLB access time: 2 ns

TLB hit ratio: 75%

Note that all PTE’s are stored in main memory. There is NO disk access. CPU’s L1 cache is the hardware cache on the CPU chip for accelerating memory accesses.

- Assuming a 1-level page table (PT), what would be the average memory access time with paging enabled? Show your work.

- Assuming a 2-level PT, what would be the average memory access time

with paging enabled? Show your work.

(a) Write the function rowSum() that receives a(double type) two-dimensional array using vectors and returns a vector consisting of the sum of elements in each row of the two-dimensional structure. The value of the returned vector at index zero is the sum of the elements in row zero of the two-dimensional structures. At index one of the returned vector is the sum of the elements in row one and so on. (b) Write a main function to test rowSum () function. Create a two-dimensional vector of at least size (5 x 5). Display the array and the content of the returned vector.
