Question

 Write a program that simulated a translation dictionary. Your program must be able to support any number of words and multiple languages. Input must be read in from a text file, where each line is in the following format: <word>:<language>:<word in english>  examples: pollo:spanish:chicken hund:german:dog perro:spanish:dog you need to support translation to and from multiple languages and English. For an English word "dog" and a language "Spanish" you'd need to be able to produce the answer "perro". Likewise, for a foreign word "perro" and a language "Spanish" you'd need to be able to produce the English word "dog". Below are three methods to get started.  you do need to show that you're able to read your input from a file. I recommend using aScanner object wrapped around a File object.   public class TranslationDictionary {    public TranslationDictionary(String inputFileName) {     // load up the dictionary from the file here   }    public String englishToForeign(String foreignLanguage, String englishWord) {     // do something here   }    public String foreignToEnglish(String foreignLanguage, String foreignWord) {     // do something here   } }
