#Summary

Create and implement a standard for embedding descriptive information (intended for visually impaired users and those using browsers or internet connections which cannot support images) in images without relying on additional html content to accompany them. The key component of this is that the descriptive information is embedded directly in the image file (though perhaps can also be requested independent of the file for limited/headless browsers which do not support images). First-guess techniques for embedding the information would be exactly those used by criminals and terrorists to steganographically hide data inside otherwise benign images (eg: coercing low-order bits in jpegs)

#HashTable exercise

In a new file create a hashtable mapping Strings to Integers

Add at least six values

print all the keys

print all the values

Part 1: A Simple Database Table

Create a Table class with three methods:

NOTE: for this exercise you only need to handle storing Strings in the Table; Modifying your finished Table class to handle columns with different data types is a good stretch assignment.

insert()

• Takes 1 parameter: a record ( String->String key-value pairs; keys represent column names in the table and values are String values stored in each column)
• Stores the records in a data structure in the Table class

Factory Method pattern

Employee factory:

— Write an abstract Employee class with name, type, and payment attributes (and corresponding accessor functions).

• Extend Employee with at least two child classes that represent types of employees (e.g.: salaried, hourly, contract, permanent, etc)
• Create an EmployeeFactory class with a makeEmployee method that takes two Strings (employee name and employee type) and returns an Employee object constructed from the corresponding child class based on the type parameter.

• Extend Employee with at least two child classes that represent types of employees (e.g.: salaried, hourly, contract, permanent, etc)
• Create an EmployeeFactory class with a makeEmployee method that takes two Strings (employee name and employee type) and returns an Employee object constructed from the corresponding child class based on the type parameter.
