Question

1) Look over the English to Spanish dictionary (engl2span.txt). The first line in the file is a value representing the current number of entries in the dictionary.

2) Look over Entry.java (model class) and IO.java (view class). They are already finished for you.

3) In Converter.java (another model class), finish the constructor (see the instructions within the file). Review the ‘translate’ method that is already completed within the Converter class.

4) Finish the Lab9.java class (controller class) which contains ONLY the main method (Again, see the instructions within the file)

please answer the you do this part........ someone save my life please...... help me computer science god!!
