How to resolve the algorithm Transliterate English text using the Greek alphabet step by step in the Java programming language

Problem Statement

A rather silly little task intended as a bit of fun as well as a simple exercise in text substitution. So, if you're a Greek speaker or an expert in ancient Greek, please don't take it too seriously! As there isn't a one-to-one correspondence between the English and Greek alphabets, we need some rules: In the case of lower-case sigma, use ς when s is the final letter of an English word or σ otherwise. Ignore Greek diacritics (accents and breathings) but use the same capitalization, spacing and punctuation as in the English text. English: The quick brown fox jumped over the lazy dog. Greek: Θε κυικ βροων φοξ ιυμπεδ οβερ θε λαζυ δογ. Transliterate the following English text into Greek using the above rules: If your language does not support the printing of non-ascii characters, then you can instead transliterate the following lower-case pangram: Just represent the Greek letters by their names in angle brackets. For example:

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Transliterate English text using the Greek alphabet step by step in the Java programming language

The provided Java code aims to transliterate English text into its Greek alphabet equivalent. This transliteration is based on a set of defined rules and character mappings from English to Greek. Here's a breakdown of the code:

  1. Import Declarations:

    The code imports the List class from the java.util package, which is used to store the test phrases for transliteration.

  2. Main Method:

    The main method is the entry point of the program.

  3. Test Phrases:

    The list contains three English phrases that will be used for transliteration.

  4. Character Pair Mappings:

    This 2D array stores pairs of characters where the first character is the English character, and the second character is its corresponding Greek equivalent.

  5. Loop Through Test Phrases:

    The program iterates through each test phrase.

  6. Sigma Conversion:

    This loop converts any 's' characters at the end of words to 'ς', which is the Greek final sigma.

  7. Character Replacement:

    The program iterates through the character pairs and replaces each occurrence of the English character with its Greek equivalent.

  8. Print Results:

    After performing the transliteration, the program prints the original English phrase, followed by an arrow (=>), and then the transliterated Greek phrase.

  9. Separator:

    This line prints a separator of 65 equal signs to visually separate the results of each test phrase.
