What is a java pig latin translator

216    Asked by AnishaDalal in Java , Asked on Oct 10, 2022

 Over the last few days I created this Pig Latin Translator just for fun. I would really appreciate it if anybody could give suggestions of how to improve the code and make the program more efficient.

Here is the GitHub link for the project.

For anybody who doesn't know Pig Latin, feel free to look at the README, which explains what Pig Latin is, and the rules of the language. The code is in PigLatin.java.

        return false;

I would suggest the following points to make this programme more object-oriented: Try using a collection object provided by Java pig latin instead of using array

String[] word = userInput.split(" ");
could be
List words = Arrays.asList(userInput.split(" "));
or using external library Guava
List words = Splitter.on(" ").splitToList(userInput);

Avoid comments where you can.

In this case I can see you can easily avoid comment if you can wrap up the particular code snippet with the meaningful name. For instance You could take the user input and breaking it in a list in separate class and call the class from your main

List words = new UserInputHandler().getInputAsList();
Try to use foreach loop over for loop:
You can easily use the foreach loop to iterate over words
for (String word : words) {
    String pigLatinWord = translateWord(word); // Translates each word individually
    output += pigLatinWord + " "; // Joins the translated word back into the output
