Primary sources such as government websites (United States Department of Labor - Bureau of Labor Statistics, United States Census Bureau, The World Bank), peer reviewed and scholarly journals in EBSCOhost (Grantham University Online Library) and Google Scholar.

Secondary and credible sources such as CNN Money, The Wall Street Journal, trade journals, and publications in EBSCOhost (Grantham University Online Library).

Non-credible and opinion based sources such as, Wikis, Yahoo Answers, eHow, blogs, etc. should not be used.

Cite all reference material (data, dates, graphs, quotes, paraphrased statements, information, etc.) in the paper and list each source on a reference page using APA style. An overview of APA 6th edition in-text citations, formatting, reference list, and style is provided here.

"You purchased a commercial building and lot for $720,000 on December 15th of 2013. The lot itself was valued at $100,000 when purchased. You sold the lot and building on June 15th of 2018. Use MACRS depreciation and note this property is non-residential real property (39 year life). What is your allowable taxable depreciation amount for year 2013?"

Answer the following in Java programming language

Create a Java Program that will import a file of contacts (contacts.txt) into a database (Just their first name and 10-digit phone number). The database should use the following class to represent each entry:
public class contact {
   String firstName;
   String phoneNum;
}

Furthermore, your program should have two classes.
(1) DatabaseDirectory.java:
   This class should declare ArrayList as a private datafield to store objects into the database (theDatabase) with the contacts names and phone numbers
       private List <contacts>theDatabase = new ArrayList(); (example from textbook)

So now you can use this statement:
theDatabase.add(new contact("Mary Smith", "8007894562");

to add a new entry to your database.

   This class should also hold the following methods:
   (1) Display All Contacts
       - as name suggests, should display all entries in database
   (2) Search Contact by Name
- uses String name
       - should return the contact or tell user if the contact does not exist
   (3) Add/Edit Contact
- uses String name and String number
       - ask user if they want to add or edit
       - prompt user for name they want to add or edit
       - prompt user for phone number
       - display all info before asking the user if they want to save
   (4) Remove Contact
- uses String name
       - search name of contact to remove
       - if contact exists, ask user if they are sure they want to delete the contact
       - remove contact

(2) Database.java:
   This is a driver class that will display the main menu with it's selections. This driver class should execute the methods held in the DatabaseDirectory.java class. The database should continue to show the main menu until the user prompts the program to exit.

Your program should closely follow this same output:

Initial Post:

Herbert Hoover and Franklin D. Roosevelt had very different attitudes about government and approaches to deal with the Great Depression. Describe each president's approach to the economic crisis, with examples from the speeches of President Hoover versus President Roosevelt.

Analyze the two approaches and consider:

• What was the long term impact of each President's actions?
• How did these different approaches change what Americans felt the government should be doing for them?

Your initial post should:

• Be 300-400 words in length.
• Describe each President's approach and consider the impact.
• Give at least one example from each President's speech.
• Use formal academic language, including MLA format citations- both parenthetical citations in your post, and full citations at the end. Please refer to the class Writing Guidelines and/or the MLA citation resources for a refresher.
