Question

Assume you want to convert from text to number. You'd need a bit of code that would convvert a word (a String) to an integer value, like this:

if (word.equals("fourteen"))
value = 14;

Write a few code fragments, and briefly explain what each one does:

Write a variable declaration that declares and creates a HashMap to hold this map.

Write one line of code that would show how to insert a (String, Integer) mapping into this map. Insert the pair ("fifteen", 15) into the map.

Write one line of code that would show how to use the map to get the integer that corresponds to some number word, such as "fourteen".

E) For the previous problem, would there be any benefit to using a TreeMap object instead of a HashMap object? Would there be any penalty?
