java programming solving problems with software week 1 quiz answers

 week 4:

	This is java programming arrays, lists and structured data week 4 quiz answers. you will not need any other answers to solve this java programing questions. You need to know about this java programming course that make you good in learning how to make arrays, lists and structured(object) of data. 1.Question 1 what is the language of secretmessage3.txt? the answer is here:
	French
	2.Question 2
	What is the first line of the message you decrypted from secretmessage3.txt? the answer is here:
	La chambre à coucher de Juliette.
	3.Question 3
	What is the language of secretmessage4.txt? the answer is here:
	German
	4.Question 4
	What is the first line of the message you decrypted from secretmessage4.txt? the answer is here:
	Drei Hexen treten auf.
	5.Question 5
	Recall that the choice to test key lengths 1–100 was arbitrary, and that the longer a key is with respect to an encrypted message, the less likely this Vigenère decryption algorithm is to work.
	How long would a key have to be, so that you could gain no information about an original message by analyzing the encrypted message? the answer is here:
	Exactly the message length
	6.Question 6
	The Vigenère decryption algorithm used in this lesson has limitations.
	In which of the following scenarios could the program return incorrect results? (Select all that are correct.) the answer is here: The language of the original message when written in sentences has different letter frequencies than the sum of individual words in the dictionary. The language of the original message has many characters not in the English alphabet. The language of the original message is not included in the dictionaries.
	7.Question 7
	Consider the Vigenère decryption algorithm described in this lesson.
	Which one of the following could be a problem? the answer is here:
	The key length is long compared with the message. introduction... About this Course Build on the software engineering skills you learned in “Java Programming Solving Problems with Software” by learning new data structures. Use these data structures to build more complex programs that use Java’s object-oriented features. At the end of the course you will write an encryption program and a program to break your encryption algorithm. After completing this course, you will be able to: help you to practice your skills in structured data(arrays, lists and objects) by doing some quiz by week, you need to answer to pass this course. size of program doesn't matter or what type of coding, you just need to know how the language work and what fundamentals do you need to learn to act with it. arrays, lists and structured data are using in many fields. structure need to be built with some data, arraylists, arrays and lists to make a useful program that can be used. testing yourself with quiz or exam, study uploaded chapter and make interview to make sure you can finally work with real world problem, and applying for job(javascript, html, stack, css, csv .....). work with all items, method and class in hours to make good work 1. Read and write data from/to files in ordered list. 2. Solve real world problems involving data files. 3. Perform quantitative analyses of structured data (e.g., finding maximums, minimums, averages). 4. Store and manipulate data in an array or Array List. 5. Combine multiple classes and objects to solve larger problems. 6. Use iterables and collections (including maps) in Java. some task you will learn to solve anther time java programming graph needed to wright with coding. anther courses help you explore high level tools to make development and help any web site developed by adding new features. and computer science is very enjoyable capturing various information, it's like university to you help you practice getting natural job. you can look or search about java programing, and you can choose to start today or not developing android, but you have to make correct decision and discover projects (written specialization, designed content). and now with this course you will begin to learn object oriented language. some reviews: -Actually, before I start this course I had not a good idea about OOP concept such as constructors, HashMap.now I have fair confidence about that. thank you duke university making such an arrangement.  -Good and practical training approach to solve real worlds problems. Assignments and quizzes are quite challenging and interesting. Greatly motivates us towards programming and problem solving skills. -The course was pretty challenging (and occasionally frustrating) for a novice programmer, but doable.\n\nI enjoyed the course, and came away with a greater understanding of computers and programming. -The programming exercises are really interesting! They make programming much more fun to study. The lecturers are all great and the lessons are engaging. Enjoyed it greatly! Thank you Duke.
