Have a pretty good idea on how to solve this program, I'm just not very accustomed to formatting well in Java for these types of problems. In java, you have full control of what's printed, I just need to get better at it, so I thought I'd post it here to receive an answer to learn from. Thanks for everything guys.

This program must use the Exclusive OR Operator ^ in java, it must also use a while loop. The way it wants to be formatted is also listed.

Write a program that uses a while loop to detect and print multiples of 19 or 23, but not both. Use the exclusive or operator as on page 93. The program should start examining integers at 100, and examine successively larger integers until 15 multiples have been detected. Correct multiples should be printed right aligned in fields that are 6 characters wide, but with only five multiples per line. The total of all correct multiples should be reported after 15 multiples have been printed.

This question is about the class Set, as discussed in the lectures. It represents a finite set of int’s. Relevant parts of Set are shown below. The integer count holds the number of elements in the Set. The array elements holds the elements themselves. The class Set also has public methods addElement, equals, isIn, and toString. They are defined as in the lectures, and you can use them if you need to.

class Set  

{  

  private int count;  

  private int [] elements;  

}

Write a public method for Set called both that takes another Set as its only parameter. The method both must return the number of elements that are in both Set’s.

For example, suppose that s1 is an instance of Set with elements 0, 2, 3, and 5. Also suppose that s2 is an instance of Set with elements 0, 1, 3, 4, and 11. Then s1.both(s2) must return 2, because there are two elements 0 and 3 that are in both sets. This is only an example! For full credit, your method both must work for any Set’s, not just the ones mentioned here.

Add bubble sort, radix sort, insertion sort, and merge sort to the code provided.

Import a data set (txt file) then do the sorting algorithm to measure how long it took and how many movements occurred.

Please write codes in C++

Program 3: Distance calc. This question is fairly straightforward. Design (pseudocode) and implement (source code) a program to compute the distance between 2 points. The program prompts the user to enter 2 points (X1, Y1) and (X2, Y2). The distance between 2 points formula is: Square_Root [(X2 – X1)^2 + (Y2 – Y1)^2] Document your code, properly label the input prompts, and organize the outputs as shown in the following sample runs.

Write bash shell scripts for the following problems and submit your answers a single.

A ) Write a linux bash shell script that reads your first and lastname as arguments and print them as shown below. In my example, I name the script as printname.sh. In the example, the two arguments follow the shell scriptname. Submit the script and output print screen.

# sh ./printname.sh Abdullah Konak 
My first name is Abdullah

Program 4: Is there a Prius version? Did you know that the average Boeing 747 airplane uses approximately 1 gallon of fuel per second? Given the speed of the airplane, that means it gets 5 gallons to the mile. No, not 5 miles to the gallon, 5 gallons to the mile. You may be questioning why such a horribly inefficient machine is allowed to exist, but you’ll be happy to find out that, because this airplane hold 568 people, it averages about 0.01 gallons per person – (100 miles per gallon per person). Your job is to design (pseudocode) and implement (source code) a program that asks the user for a distance the plane has to fly (i.e. the length of the trip) and also asks the cost of jet fuel (which is currently $1.80 per gallon). The program should then calculate the total fuel charges to make the trip. Next, ask the user how many people will fly, as well as the average cost of a ticket. Finally, print the total profit made (or lost) and the average gas mileage per person. Document your code and properly label the input prompts and the outputs as shown below.

In the second task, you will write a Java program that validates an input to see whether it matches a specified pattern. You will have to read a bit about regular expressions for this Lab.

1. Prompt the user to enter the email address.

2. Read the user input as a String.

3. A regular expression that specifies the pattern for an email address is given by “[a-zA-Z0- 9.]++@[a-zA-Z]++.(com|ca|biz)”. Use this as the input to the matches method in the String class and output the result returned by the method.

4. Prompt the user to enter the full name.

5. Full name should have First name, zero or Middle names and the Last name. For this purpose, we will assume a name (first, middle or last) is a set of characters without any spaces. Some examples are “John”, “McDonald”, “smiTh”. The names are separated by exactly one space. Write a regular expression to represent this pattern.

6. Use the matches method in the String class to validate the name entered by the user and output the result returned by the method.

A possible dialogue with the user might be;

Please enter the email address: [email protected]

true

Please enter the full name: Malaka Second Third Walpola

Question 1 (10)
Create a class Student with public member variables: Student name, student number, contact number, ID number. The following specifications are required:
 Add init() method of the class that initializes string member variables to empty strings and numeric values to 0. (2)
 Add the method populate() to the class. The method is used to assign values to the member variables of the class. (2)
 Add the method display() to the class. The method is used to display the member variables of the class. (2)
 Create an instance StudentObj of the class Student in a main program. (2)
 The main program should prompt the user to enter values for five students. The attributes should be assigned to the instance of Student using its populate() method, and must be displayed using the display() method of the instance of Student. (2)

Please make the answer simple and straightforward for a beginner intro to python . Thank you

JAVA PROGRAMMING

Part 1

1. Create a class Student, with attributes id, first name, last name. (All the attributes must be String)
   1. Create a constructor that accepts first name and last name to create a student object.
   2. Create appropriate getters and setters
2. Create another class StudentOperationClient, that contains a main program. This is the place where the student objects are created and other activities are performed.

• In the main program, create student objects, with the following first and last names.
• Chris Evans
• Mila Kunis
• Adam Sandler
• Emma Watson
• Jennifer Lawrence
• Dwayne Johnson.

• Once you create the student objects, use System.out.println, function to print the values in following format:
• First Name: XXXXXX , Last Name: XXXXXXXX

Part 2

3.       Create an integer attribute to student class, name it as studentScore. No getters and setters are needed for this attribute.

4.       When you create the Student object using the constructor, assign a random number to score attribute – random number should be between, 50 and 100.

5.       Create a new method in Student object, called getGrade(), that returns a String.

a.       The output method should return the following

If the score is >91, the return should be A,

Likewise B for >81 , C > 71, D > 61, and F for all others.

6.       Modify the StudentOperationsClient’s main program, to print the following.

First Name: XXXXXX , Last Name: XXXXXXXX    Letter Grade: XX

Part 3

1. Perform the steps 2, and 6, using arrays in Java. So instead of 6 different objects, you will create an array of 6 student objects and iterate them using a for loop.
2. Create a new method in student, getGradeDescription() – that returns a string and takes a String as input.

Use switch case control statements to return the following,

• A – Excellent
• B – Fair
• C – Average
• D – Poor
• F – Fail,

•&νβσπ;&νβσπ;&νβσπ;&νβσπ;&νβσπ;&νβσπ;&νβσπ;&νβσπ; and any other input as “INVALID”

• Once you create the student objects in the ARRAY, use System.out.println, function to print the values in following format:

First Name: XXXXXX , Last Name: XXXXXXXX Class Performance: <GradeDescription>

Design and implement a program (name it Coins) that determines the values of coins in a jar. The program prints out the total dollars and cents in the jar. The program prompts the user to enter the number of coins (quarters, dimes, nickels, and pennies). Print out the number of coins entered for each coin type on separate lines followed by the total amount of money in the jar as dollars and cents as shown below.

Sample run 2:

Enter number of quarters: 3
Enter number of dimes: 0
Enter number of nickels: 0
Enter number of pennies: 3

You entered 3 quarters
You entered 0 dimes
You entered 0 nickels
You entered 3 pennies

Your total is 0 Dollars and 78 Cents.
