Question

Design and code a SWING GUI to translate text entered in English into Pig Latin. You can assume that the sentence contains no punctuation. The rules for Pig Latin are as follows: 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. 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 separate JTEXTAREA for the translated text. Add a JBUTTON with an event to perform the translation. 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
