9/21 Fri	Review	14	Pg 145-146 (ALL), Pg 149-151 ALL PROJECTS: 4-5, 4-10 4-A: Write an application that computes e^x by using the formula: e^x = 1 + x/1! + x^2/2! + x^3/3! + … (Note: ! = factorial. e = Euler’s number. Let me know if you need help with these mathematical concepts!). 4-B: Write a program that reads an integer value between 0 and 100 (inclusive) representing the amount of a purchase in cents. Produce an error message if the input value is not in that range. If the input is valid, determine the amount of change that would be received from one dollar and print the number of quarters, dimes, nickels, and pennies that should be returned. Maximize the coins with the highest value. Example: Purchase amount: 36 Your change of 64 cents is given as: 2 Quarters 1 Dime 0 Nickels 4 Pennies Program should correctly determine whether the plural form of the coin should be used (i.e. 1 Dime vs 2 Dimes) 4-C: You're going to create a bar-chart! Write an application that prompts user for 10 numbers (each number needs to be between 1 and 30). For each number read, your program should draw a line containing the number of adjacent asterisks. For example, if the user inputs the number seven, your app would print: ******* ---BONUSES: Make it GUI; allow user to name each bar and make the name part of the display; don’t limit number to 30, if user wants number that would cause line to be too long, use scale factor and inform user of scale factor in final display (scale factor has to apply to all bars for display to be valid)

9/26-9/27 BLOCK	5.6	17	Read pgs 183-194: 5.6 (#1-3), Pg 195-196 (ALL) Links: Static Subroutines and Variables and Constructors and The "truth" about declarations PROJECTS: 5-3, 5-5, 5-8, 5-9 5-A: Create a class called “Date” that includes three pieces of info as instance variables: month, day, and year. You’ll need a constructor that initializes all three instance variables. Write a method to check that the values given are valid and prompts user for new values they aren’t. Provide an accesssor and mutator method for each variable. Provide a method displayDate that displays the date separated by forward slashes (/).
9/28 Fri	6.1	18	Read pgs 199-212: 6.1 (#1-5)

10/8 Mon	Review	22	Do:  Pg 299-301 ALL PROJECTS: 6-8 through 6-10, Pg 301-302 #3, #4, Critical Thinking 6-A: A right triangle can have sides that are all integers, i.e. 3-4-5 or 5-12-13. If the sides are all integers, these numbers are called a "Pythagorean Triple." Write an application to find ALL Pythagorean triples for hypotenuses less than 501. Hint: use a triple nested for-loop. 6-B: Calculate π from the infinite series: 4 – 4/3 + 4/5 – 4/7 + 4/9 – 4/11 + … Print a table that shows the value of π approximated by 1 term, 2 terms, 3 terms, etc. How many terms of this series do you have to use before you first get 3.14? 3.141? 3.1415? 3.14159? (Put comment in code telling me or use System.out.println().) 6-C: Write an application that displays the following patterns separately one below the other. You must use for loops to generate the patterns to receive credit.
