Spanish Vocabulary Helper

• For this assignment, we are going to work with adding and removing data from arrays, linear search, and File I/O.
  • In addition, you will learn to work with parallel arrays
• This program will assist an English-speaking user to build their vocabulary in Spanish
• This program will read a file containing a list of words in English and another containing the translation of those words in Spanish.
• The words and corresponding translations should to be stored in two separate but parallel arrays.
  • In other words, the indices of the English words array will match the indices of the Spanish words array.
  • Thus the word in English at index 0 in the first array, will match the translation at index 0, in the second array, and so on.
• You may assume that the user will not store more than 1000 words and translations.
  • Therefore, your arrays should be declared of length 1000.
• Create two new text files inside of your project folder in Eclipse:
• Name these text files english.txt and spanish.txt
• Copy and paste the following alphabetized list of English words into the english.txt file:

bear
black
blue
cat
cow
dog
fall
gray
green
purple
red
spring
summer
to be
to be able
to go
to love
winter
white
yellow

• Copy and paste the following list of Spanish translations of the above words into the spanish.txt file:

oso
negro
azul
gato
vaca
perro
otono
gris
verde
morado
rojo
primavera
verano
ser
poder
ir
amar
invierno
blanco
amarillo

• Read in the words from each file into two separate arrays, one array called arrayEnglish and one array called arraySpanish.
• Hint: you can use a variable to count how many values are in each file as you are reading in the data, and use this information to save the number of values currently stored in each array?
• Next, you will need to write a menu-driven program to allow the user to complete 3 tasks:
  • Add a new word and its translation (choice 1)
  • Remove a word and its translation (choice 2)
  • Display the Spanish translation of an English word (choice 3)
  • Quit (choice 4)
• For the add menu option, the program should do the following:
  • Prompt the user for a word in English and its transation in Spanish, and a position in the arrays at which to insert these new words.
  • Call the insert method twice to insert each word in the correct array
  • Hint: don't forget to update the count of words
• For the remove menu option, the program should do the following:
  • Prompt the user for the a word to remove in English.
  • Search for the position of this word inside arrayEnglish
  • If the word is not in the array, it should provide an error message to the user (see sample output below)
  • Otherwise, remove the word and its translation in Spanish
  • Hint: don't forget to update the count
• For the search for a translation menu option, the program should do the following:
  • Prompt the user for the a word to search in English.
  • Search for the position of this word inside arrayEnglish
  • If the word is not in the array, it should provide an error message to the user (see sample output below)
  • Otherwise, display the word and its corresponding translation in Spanish
• For the exit menu option, the program should do the following:
  • Prompt the user to enter the name of a file in which to print the words
  • End the program
• Note that you should also provide an error message if the user types an incorrect menu option (see sample output below) or if the array is full and no new values can be added (hint: you can make a check in your menu option 1 for this case)
• To begin, copy and paste the starter code into a file called Translator.java
• Make sure that you implement and call all of the methods whose signatures are specified below
• Note that you made add any additional methods that you like to complete the program
• When your program is working *identically* (including spacing and wording!) to the sample output, please upload Translations.java to Canvas.
