Design and code a Swing GUI to translate text that is input in English into Pig
Latin. You can assume that the sentence contains no punctuation. The rules for
Pig Latin are as follows:
a. For words that begin with consonants, move the leading consonant to the end
of the word and add “ay.” Thus, “ball” becomes “allbay”; “button” becomes
“uttonbay”; and so forth.
b. For words that begin with vowels, add “way” to the end of the word. Thus,
“all” becomes “allway”; “one” becomes “oneway”; and so forth.
Use a FlowLayout with a JTextArea for the source text and a separate JTextArea
for the translated text. Add a JButton with an event to perform the translation. A
sample application is shown below with the text translated to Pig Latin.
To parse the source text, note that you can use the Scanner class on a String . For
example the following code:
Scanner scan = new Scanner(“foo bar zot”);
while (scan.hasNext())
{
System.out.println(scan.next());
}
will output
foo
bar
zot
