Objects and Classes

Use Netbeans
One class, one file. Don't create multiple classes in the same .java file
Don't use static variables and methods
Encapsulation: make sure you protect your class variables and provide access to them through get and set methods
all the classes are required to have a constructor that receives all the attributes as parameters and updates the attributes accordingly
all the classes are required to have an "empty" constructor that receives no parameters but updates all the attributes as needed
Follow Horstmann's Java Language Coding Guidelines
Organized in packages (MVC - Model - View Controller)

Create a NetBeans project with
<default package>
App.java
Person.java
Functionality
The application App creates 5 Person objects
using the data below
name=Marcus Allen, weight=200, hometown=Upper Marlboro, Md., highSchool=Dr. Henry A. Wise, Jr.
name=Kyle Alston, weight=180, hometown=Robbinsville, N.J., highSchool=Robbinsville

C Coding Project

MUST BE IN C




Write a program that manages a small list of students in a university:
Student struct should contains the flowing data members (/subdata elements):
fname, lname, birthYear (ex. 1990), gpa (ex. 3.68).
Max number of characters for fname and lname is 20.
User should be prompted with a menu of options to choose from (use switch statement):
0: Exit, 1: Load data from the file, 2:  Print all students' information, 3: Generate report based on GPA , 4: Add student 5: Update the file.
The above line should be printed out for the user as the menu with each option in one line. The menu should be presented to the user each time that the user wants to choose a new option.
Option 1: "students.csv" with students' information has been provided, download and place the file in your project/program directory (folder). This option needs to read the information from the file and populate an array of structures (passed to it from the main).

some q/a to help it from an instructor

Operator overloading Q/A

Q: This is from the lecture but I don't really understand what's going on here:
Date d4;
//later
d4 = d1;

A: Here we can do direct assignment if we overloaded the assignment operator for the Date

Q: Assignment or copy constructor?

A:

Date d1;

Date d2 = d1;//this is a copy constructor. The same as if I said:

Date d2(d1);

//this is assignment:

Date d1, d2;

////later

d1 = d2;

Q: "But what do I add? Days? Months? Years? There is some ambiguity here. Not to overload. "

Wouldn't it do all of them?

A: If I have:

Date d;

......

d = d + 5;
Is it clear what do I add to that date d?

Q: Why is that istream and ostream?

A: in one case you enable the direct input to the Date, in other

Fix two specific methods in this assignment

Basically, this was done by another expert who took on way too many assignments and decided to return null on a couple of functions, effectively allowing the program to compile but not actually doing anything; thus, I ended up failing a lot of test cases.

The two functions I need fixed are public E element() and public E peek() in PriorityTree.java

I am also attaching the log text file for the test cases that were failed. Just focus on the assertion errors for element() and peek(), I'm only allowed to fix those particular methods because they're responsible for so many of the test cases.

Reference the txt file; I'm attaching all the classes (there are 3) for your reference but mainly you'll be working with PriorityTree

You're just rewriting two functions within a class so please don't charge too much

Create a program in C showing the time difference between accessing data in a sequential file and accessing data in a random-access file

Create a program in C showing the time difference between accessing data in a sequential file and accessing data in a random-access file.
1) Use the information of minutiae (with random data) (source code and explanation in the details file).
2) Create millions of records.
3) Compute execution time using the proper instructions in C.
Create a report showing the time difference of writing millions of records, reading all the records, and accessing to 10,000 random records.
