Question

(Pig Latin) Write an application that encodes English-language phrases into pig Latin. Pig Latin is a form of coded language. There are many different ways to form pig Latin phrases. For simplicity, use the following algorithm: To form a pig Latin phrase from an English-language phrase, tokenize the phrase into words with an object of class StringTokenizer. To translate each English word into a pig Latin word, place the first letter of the English word at the end of the word and add the letters “ay.” Thus, the word “jump” becomes “umpjay,” the word “the” becomes “hetay,” and the word “computer” becomes “omputercay.” Blanks between words remain as blanks. Assume the following: The English phrase consists of words separated by blanks, there are no punctuation marks and all words have two or more letters. Method printLatinWord should display each word. Each token returned from nextToken is passed to method printLatinWord to print the pig Latin word. Enable the user to input the sentence. Keep a running display of all the converted sentences in a textarea.

Short answer

Read input, tokenize into words, convert each word using Pig Latin rules, and display the result.

Step-by-step solution

Understand Pig Latin Rules

To encode a word into Pig Latin: take the first letter, move it to the end, and add 'ay'. For example, "jump" becomes "umpjay", "the" becomes "hetay".

Parse the Phrase

Use a StringTokenizer to break the input phrase into individual words. This will allow us to process each word separately for Pig Latin conversion.

Create Method to Convert to Pig Latin

Define a method called `printLatinWord` that takes a word as input. The method will rearrange the word according to Pig Latin rules and return the transformed word.

Implement Word Conversion

Inside `printLatinWord`, take the first character of the word, append it to the end of the word, then add "ay". Return this new string as the Pig Latin word.

Iterate Over Words and Encode

For each token (word) in your StringTokenizer, call the `printLatinWord` method, passing the token to convert it to Pig Latin.

Display Results

Collect each converted Pig Latin word and concatenate them with spaces to form the final Pig Latin phrase. Display this phrase to the user.

Keep Continuous Display

Use a text area in your application to continuously append and display new Pig Latin phrases as they are processed, so the user can see a collection of converted phrases.

Key concepts

StringTokenizer

The `StringTokenizer` class in Java is a utility that helps break down strings into smaller pieces, known as tokens. This tool is especially useful in text processing tasks where you need to handle formatted data, like converting a sentence into Pig Latin.

By using `StringTokenizer`, you can split a sentence into individual words. In the case of converting an English sentence to Pig Latin, these individual words, or tokens, can then be processed separately. The tokenizer identifies spaces between the words to know where one word ends and another begins.

It’s important because:

• It allows separate handling of each word.
• Reduces complexity by simplifying parsing.
• Integrates easily into loops to process each word in a sentence.

The simplicity of `StringTokenizer` makes it a valuable tool in text processing, especially for language translation tasks, like our Pig Latin conversion.

printLatinWord method

The `printLatinWord` method is a customized function designed to convert any English word into its Pig Latin equivalent. It accepts a single word as an argument and returns an encoded word in Pig Latin format.

Here's a brief step-by-step overview of what happens within this method:

• Extract the first letter of the input word.
• Move this letter to the end of the word.
• Append "ay" to the end of this restructured word.

This method is crucial in the Pig Latin conversion process because it encapsulates the logic needed to transform each word according to the Pig Latin rules. It's called for each token extracted by `StringTokenizer`, ensuring each word is correctly processed.

English to Pig Latin translation

In this task, the English to Pig Latin translation is achieved through a simple set of rules, which make it easy to transform an English phrase.

The rules are as follows:

• Take the first letter of an English word.
• Move this letter to the end of the word.
• Add "ay" to the end.

This approach ensures a systematic transformation from English to Pig Latin. Let's see some examples to clarify:

- "jump" becomes "umpjay"

- "the" becomes "hetay"

- "computer" becomes "omputercay"

Notice how each English word is altered using the same rule, making this method both reliable and consistent for a variety of words.

text processing

Text processing is the act of manipulating text to achieve a new format or extract information. In the realm of programming, it involves converting and transforming text data.

For Pig Latin conversion, text processing comes into play right from the input stage up to the display of the results:

- **Input Handling:** Accepting and managing user input data, often as strings.

- **Breaking Down Sentences:** Parsing the input through classes like `StringTokenizer` to break it into manageable tokens.

- **Word Transformation:** Using functions like `printLatinWord` to implement the desired text transformation, in this case, converting words to Pig Latin.

- **Output Display:** Continuously updating and displaying the output for the user to ensure the process is clear and dynamic.

By focusing on these aspects of text processing, we can create efficient applications that transform and handle text data effectively.
