2. Modify the loop from question 1 so that if one of the random numbers is 5, it prints "You win" and ends the loop.
3. Write a while loop that prints the digits -100 up to 100.

1. Watch The Monty Hall Problem.
2. Watch Monty Hall's Denial of the problem.
3. Download and play this working version of MontyHall.java
4. Modify this game so that the user can play repeatedly in a single run of the program. Count the number of times the player wins, and print the percentage of wins at the end of the program.

1. Watch this video on Ending a Loop with a Sentinel Value (C++)
2. Write a program that reads any number of grades in numerical format, averages them, and then displays the average to the user. Use a while or do...while loop to enter grades and a sentinel variable to indicate when to stop entering grades. Allow the program user to determine when to stop entering the grades.

1. Watch this video on the For Loop
2. Read this Going Loopy Tutorial.
3. Complete these Loops Exercises **on paper**.
4. When you are done, confirm your answers by running the code.

1. Write a program to find the sum of first 42 positive numbers using a for loop.

1. Write and run a program that reads a positive integer n and then prints a triangle of asteriks in that number of rows. Use two nested for loops. For example, if n is 4, then the output would be:

   *
   **
   ***
   ****

   Hints to solve this algorithm:
   1) Print a single star using System.out.print("*").
   2) Get the program to print n stars on one line (a single for loop).
   3) Then get it to print an nxn square of stars (another for loop around the first for loop). Use System.out.println(""); to add a hard return where you need one.
   4) Now change only one thing in the program will give you the triangle you seek.
   
   NOTE: Solutions with two for loops that are not nested, or with only one for loop will not be accepted.

1. Creates an array of 200 integers
2. Loads the array with 200 random values between 1 and 100 (Hint: use a for loop)
3. Prints the elements of the array in order from index 0 to index 199. (Hint: use another for loop)
4. Prints the elements of the array in REVERSE order from index 199 to index 0. (Hint: use a 3rd for loop)

Theory: When a variable with primitive data type is passed to a method, it is 'pass by value', which means a copy of the variable is passed into the method. When an array or object is passed to a method, thereference is 'passed by value', which means a copy of its reference is passed into the method. If the method modifies an array that has been passed in, the original array gets modified.

1. Download this incomplete program.
2. Complete the method absoluteValues() that replaces all the negative numbers in an array of integers with their absolute values.
3. Complete the method indexOfMinimum() that returns the index of the minimum value stored in an array.

1. Declare a 10x10 2D array of integers.
2. Populate the array with random integers between (and including) 0 and 9.
3. Call a method named print2DArray and pass it the above array. The method will print the array by line as shown below:

        1 2 3 4 0 9 4 3 2 6 
        4 3 2 1 5 3 4 2 0 9 
        5 6 7 8 5 3 7 5 8 1 
        8 7 6 5 0 8 9 5 7 3 
        5 6 7 8 5 3 7 5 8 1
        0 9 8 0 5 3 2 5 3 7
        4 3 2 1 5 3 4 2 0 9
        7 2 0 8 9 2 6 4 6 5
        1 0 7 9 3 5 7 4 6 3
        0 5 4 9 4 9 0 5 3 5
   	 

4. Call a method named findSum and pass it the above array. The method will find the sum of the numbers in the array and print it.

In this assignment, you will learn to read data from a file, process the data, and write data to a file. The skills learned here will be required to complete Assignment 2.

Watch Ms Wear's Lesson on File I/O (Input/Output) to complete this exercise.

1. Create a new Eclipse Project. Call your main class FileInputOutput.
2. Copy and paste File Input and Output Code into your main class.
3. Copy and paste this list of numbers. Save it into a text file called nums.txt in the bin folder of your Eclipse project.
4. Run the code. You should see the contents of nums.txt print to the console.
5. Look into the Eclipse Project folder using Windows Explorer (the file manager on Windows) and notice a new file called output.txt has appeared. Open it, and you should see a duplicate of the numbers in nums.txt. This file was created by your program!
6. Now uncomment line 21, and write the method sumIntegers(). Run the program.
7. It should print the sum of the values in the console. Check with other students to see if your sums agree.

1. Put this four letter list in a file called dictionary.txt.
2. Format the dictionary so that the first line contains all the words beginning with a, the second line contains all the words beginning with b, and so on.

You will be asked to create a program that utilizes the methods written in earlier programs: sameLetters, isValidWord, getRandomWord, and shuffle.

You will be assigned a partner, and one of the projects below. Enhanced use of dialog boxes to maximize user friendliness will be assessed. (see block below)

1. Second Hand :

   Create a fun to play computer game out of this old calculator game. Part of the design process is automating anything that can be programmed and making it fun for the user. There must be a 1 player game (against a computer) and a 2 player version. Algorithms, user interface and error checking evaluated. It is expected that some of the JOptionPane Resources below will be used to improve your user interface.

2. 1001: Create a fun to play computer game out of this old calculator game described below. Part of the design process is automating anything that can be programmed and making it fun for the user. There must be a 1 player game (against a computer) and a 2 player version. Algorithms, user interface and error checking evaluated.
   1001 Game Description
   
   EQUIPMENT: 1 Player, 1 Calculator, 1 Pair of Dice
   
   OBJECT: To get to 1001 as fast as possible.
   
   THE PLAY: Throw the dice and consult the following chart:
   1 = +
   2 = -
   3 = *
   4 = /
   5 = %
   6 = +
   One die will be used to determine the number entry. The other will be used in conjunction with the chart to determine operation entry. For example, if the roll was 3 and 5, you could enter 3 as the number and enter * as the function. Or, you could enter 5 as the number and enter * as the function. You have to get EXACTLY to 1001 in the fewest number of turns. Each roll of the dice means you enter one number and one operation.
   
   STRATEGY: If the dice allow it, build up slowly so you will have some choice in later rolls. Take your time in deciding which number will be played and which number will determine the function. Try to plan for the best chances for the next roll. If you get it can serve to your advantage as it will get you to a number from which you will easily achieve 1001.
   
   SAMPLE PLAY
   

   Roll	Die Rolled	Chosen Number	Chosen Operation	Calculation this Turn	New Total with Resulting Expression
   1	6, 1	6	+	6	6 +
   2	5, 3	5	*	5 + 6 = 11	11 *
   3	1, 4	4	+	11 * 4 = 44	44 +
   4	1, 1	1	+	44 + 1 = 45	45 +
   5	4, 2	4	-	45 + 4 = 49	49 -
   6	1, 4	4	+	49 - 4 = 45	45 +
   7	1, 4	4	+	45 + 4 = 49	49 +
   8	3, 6	6	*	49 + 6 = 55	55 *
   9	6, 3	6	*	55 * 6 = 330	330 *
   10	1, 3	3	+	330 * 3 = 990	990 +
   11	6, 6	6	+	990 + 6 = 996	996 +
   12	1, 5	5	+	996 + 5 = 1001	<==========WIN
