For each numerical value 0, 1, 2, 9 (0 <= NUMBER <= 9), embedded in a sentence, convert that value to its equivalent English text. Print the converted sentence both to the screen and to an output file.

Your input file consists of a variable number of records. Each record is a sentence of length <= 80 characters. More than one numerical value in the given range may appear in a sentence. You must deal with upper and lower case issues. If a line begins with a single digit, write that digit as a word starting with an uppercase letter. See the examples below.

Examples: Input Record: 3 foxes were chasing 5 rabbits and 10 ducks.

Output Record: Three foxes were chasing five rabbits and 10 ducks.

Input Record: I used 3 eggs out of the 12 for the cake.

Output Record: I used three eggs out of the 12 for the cake.

Input Record: 1 picture is worth 1000 words.

Output Record: One picture is worth 1000 words.

Input Record: There are 260 students enrolled in Java.

Output Record: There are 260 students enrolled in Java.

Create the following as an input file for testing.

The 8 eggs were separated into 3 groups. 5 boys and 7 girls were present. He was 1 hour and 5 minutes late. She ate 3 dozen doughnuts! 4 dogs were chasing 3 cats. The captain said, This is the 0 hour. I tried to call you 9 times today; Ann tried 6 times!! The 12 firemen worked quickly.

Prompt the user for the name of the input file. Name your output file outSentences.txt . Save the output file in the same directory as your code to make grading on different systems easier.

More details: Create two class files. One class is the Converter. It has a StringBuilder field for the original sentence and a String field for the converted sentence. The constructor will call a method to convert the original sentence. You are to use only a select few methods of the StringBuilder class for the conversion. These are the only methods of the String and StringBuilder class you are permitted to use:

StringBuilder: constructors, charAt( ), indexOf( ), length( ), replace( ) String: constructors, charAt( ), length( )

You are also permitted the use of the isDigit( ) method from the Character class.

The second class is the driver class The driver will contain the main( ) method. The main( ) method will open a file for input. Read the file line by line and send each line to the Converter class. The main( ) method will call the get method( ) of the Converter class to get the converted string, and print this string both to the screen and to a file.
