Explain the pig latin translator java.
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.

import java.util.Scanner;
public class PigLatin {
private static Scanner scan = new Scanner(System.in);
public static void main(String[] args) {
System.out.print("Enter one or more words that you would like to translate to Pig Latin: ");
final String userInput = scan.nextLine();
scan.close();
String[] word = userInput.split(" "); // Splits the string into an array of words
String output = "";
for (int i = 0; i < word> String pigLatinWord = translateWord(word[i]); // Translates each word individually
output += pigLatinWord + " "; // Joins the translated word back into the output
}
System.out.println("Original Word(s): " + userInput);
System.out.println("Translation: " + output + "n");
}
public static String translateWord(String word) {
String lowerCaseWord = word.toLowerCase();
int pos = -1; // Position of first vowel
char ch;
// This for loop finds the index of the first vowel in the word
for (int i = 0; i < lowerCaseWord> ch = lowerCaseWord.charAt(i);
if (isVowel(ch)) {
pos = i;
break;
}
}
if (pos == 0) {
// Translating word if the first character is a vowel (Rule 3)
return lowerCaseWord + "yay"; // Adding "yay" to the end of string (can also be "way" or just "ay")
} else {
// Translating word if the first character(s) are consonants (Rule 1 and 2)
String a = lowerCaseWord.substring(pos); // Extracting all characters in the word beginning from the 1st vowel
String b = lowerCaseWord.substring(0, pos); // Extracting all characters located before the first vowel
return a + b + "ay"; // Adding "ay" at the end of the extracted words after joining them.
}
}
// This method checks if the character passed is a vowel (the letter "y" is counted as a vowel in this context)
public static Boolean isVowel(char ch) {
if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' || ch == 'y') {
return true;
}
return false;
}
}
Regarding the pig latin translator java, I would suggest the following points to make this programme more object-oriented: Try using a collection object provided by Java 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
}
Again as suggested before you can wrap the code inside for loop in a separate class so that you could call
for (String word : words) {
output = new PigLatinTranslator(word, output).translate();
}
