Using the provided m1_mbox.txt, write a program that reads the data from the file, locates the lines containing sender information (those lines begin with 'From:'), and extracts just the email address of the sender of each message. It should then duplicate the set of email addresses for senders, and write the duplicated list to a file called senders.txt, so that each sender appears in the output file only once. In addition, your program should print to the screen the following stats: total number of email messages in the file, and number of unique senders. Your program should expect the input and output files to be in the same directory and you should hardcode this into your program (that is, do not use command line arguments).

Using the data structure concept of topological ordering,demonstrate using pseudocode how you can implement an operation to schedule picking during a delivery process in a warehouse.

Design a class named Person and its two subclasses named Student and Employee. Make Faculty and Staff subclasses of Employee. A person has a name, address, phone number, and e-mail address. A student has a class status (freshman, sophomore, junior, or senior). Define the status as a constant. An employee has an office, salary, and date hired. A faculty member has office hours and a rank. A staff member has a title. Override the toString method in each class to display the class name and the person’s name.

Write a test program that creates objects of Person, Student, Employee, Faculty, and Staff, and invoke their toString() methods.                  

Consider the following description of an enterprise.

An auction Web site has items for sale that are provided by sellers. Each item has an opening price, a description, and ending time. Customers submit bids. The highest earliest bid submitted before the ending time is the winning bid and the item is sold to the bidder. Each seller must pay 5% of the winning bid. The auction company wants to be able to analyze the sales behavior of its customers and sellers and so must keep track of all bids and sales.

1. What entity classes are mentioned in the description?
2. List seven attributes that will be used in a data model for the auction company.
3. What relationship types exist between the entity classes of part a?
4. Give three example entities of each class listed in part a.

A personal phone directory contains room for first names and phone numbers for 30 people. Assign names and phone numbers for the first 10 people. Prompt the user for a name, and if the name is found in the list, display the corresponding phone number. If the name is not found in the list, prompt the user for a phone number, and add the new name and phone number to the list.

Continue to prompt the user for names until the user enters quit. After the arrays are full (containing 30 names), do not allow the user to add new entries.

Use the following names and phone numbers:

This code was provided to start with:

import java.util.*;

The bits transmitted by four stations A, B, C and D are multiplexed using Code Division Multiplexing (CDMA). Assume A transmits a 1 bit, B transmits a 0 bit, C transmits a 1 bit, and D is silent. Assume the following are the chip sequences of the four stations, answer below questions: SA = (-1 -1 -1 +1 +1 -1 +1 +1); SC = (-1 -1 +1 -1 +1 +1 +1 -1) SB = (-1 +1 -1 +1 +1 +1 -1 -1); SD = (-1 +1 -1 -1 -1 -1 +1 -1)

i) What is the transmitted sequence?

ii) Show how the receiver determines station B’s transmission.

In this program write a method called upDown that takes three integers as arguments and returns one of these 3 strings:

• "increasing" if they are in strictly increasing order (note that 3,3,4 - are not strictly increasing),
• "decreasing" if they are in strictly decreasing order.
• "none" otherwise.
  I recommend you use a complex condition to check for this (that is, have a single if statement with one big question).

In the main method do the following:

• read three integers from the user and call upDown for those integers, save the result in a variable, res1, and then print it.
• read again three integers from the user and call upDown for those integers, save the result in another variable, res2, and then print it.
• compare res1 and res2 and print "same" or "different"

read three integers from the user and call upDown for those integers, save the result in a variable, res1, and then print it.

---------- Sample run 1:
Enter three integers separated by spaces: 2 0 9
These numbers are in order: none
Enter three integers separated by spaces: 17 90 567
These numbers are in order: increasing
different

---------- Sample run 2:
Enter three integers separated by spaces: 90 9 1
These numbers are in order: decreasing
Enter three integers separated by spaces: 7 3 1
These numbers are in order: decreasing
same

---------- Sample run 3:
Enter three integers separated by spaces: 3 3 4
These numbers are in order: none
Enter three integers separated by spaces: 8 1 16
These numbers are in order: none
