Create a Program to Implement Word Shuffling in Java Assignment Solution

Instructions

Objective

Write a program to implement word shuffling in java.

Requirements and Specifications

In the first section to complete a java assignment, you will write methods to perform basic text analysis on a document.

Count the number of words in the text. You can assume that words are separated by a space.

Count the number of sentences in the text. You can assume that a new sentence begins following a punctuation mark. Note: you only need to consider the

following punctuation: "." "?" "!"

Find the top 10 words in the text and return the number of times they occur. This information should be outputted to a text file in an easy-to-read format. Note: The top 10 words refers to the 10 most frequently used words in the text file.

A method that accepts a string as a parameter and returns True if the word is found in the text document and False otherwise.

Here is a text file with a portion of President Barack Obama's acceptance speech. You can test your programs using this text file. PoliticalSpeech.txt

Here is the code that you can use to read in a text file from your computer. You will need to add the path in the appropriate place to identify where the text file is saved on your own computer.

You may not use any of the built-in Java methods or libraries that many entirely solve any of the above problems. You can use built-in methods such as "length()" for finding the length of a string.

Part 2: WORD SHUFFLE

The Word Shuffle game is a puzzle that shuffles the letters of a word. For this assignment, your program will select a word and will create a jumble or mixed up version of the word. The player of the game must then guess what the original word was before it had been shuffled.

Write a program that selects a word and produces a “jumbled” version. For example, the letters of the word “TAKEN” might be scrambled as “AKNET”.

The shuffling of the letters should be random. This means, for example, that your program shouldn't follow a predictable shuffling algorithm, such as always moving the first letter of a word to the end of the word. Ten shuffles is more than enough to jumble a 5 or 6 letter word. Hint: To randomize the scrambling, use the Random class.

Here is a link to a dataset of English words. This is the dataset that you should use to select a word to scramble. The word should be selected at random.

Here are the specific rules for the game:

The game is played with two players competing against each other to get the highest score. During each turn, the player is presented with a scrambled word. They need to guess the original word before it was shuffled.

During each turn, the player gets a maximum number of 5 chances to guess the original word. Once the player has entered 5 guesses, the word is revealed, the player loses their turn, and game-play is transferred to the other player.

Your program should keep track of the players' scores. Here is how points are accumulated:

If the player guesses the word correctly on their first try, they get 5 points.

If the player guesses the word correctly on their second try, they get 4 points.

If the player guesses the word correctly on their third try, they get 3 points.

If the player guesses the word correctly on their fourth try, they get 2 points.

If the player guesses the word correctly on their fifth try, they get 1 point.

If the player does not successfully guess the word within five tries, they get 0 points, and game-play is passed over to the opposing player. Before the end of their turn, the correct word should be revealed to the player.

At any point, the player should be able to forfeit their turn to request to see the word. If the player chooses to have the word revealed, they will not gain any points for that round.

As soon as a player reaches a score of 40 or greater, the game is over and that player wins the game.

You may not use StringBuilder to solve this problem.

Part 3: Encryption and decryption of messages

To complete java assignment, you will code a ciphering program. A cipher is an algorithm for performing encryption or decryption of messages. We will use a cipher algorithm that I have devised called step cipher.

Task # 1: Write a method called encode that will encode a message using a specified key that is in the range 0 through 25.

The header of the method should be as follows:

public static String encode(String message, int key)

The message may include spaces and punctuation characters, but only the lower case characters ‘a’ through ‘z’ should be encoded.

Each of the letters of the alphabet will map to the letter key positions further along in the alphabet. For example, if the key value is 4, the letters of the alphabet will be mapped as follows:

A -> E

B -> F

C -> G

and so on...

Task # 2: Write a java assignment that will decode a message using a specified key that is in the range 0 through 25. The header of the method should be as follows:

public static String decode(String codedText, int key)

The coded text may include spaces and punctuation characters, but only the lower case characters ‘a’ through ‘z’ should be decoded.

You may not use StringBuilder to solve this problem.

All code needs to be sufficiently commented.
