Formatting Output

File Deli.java contains a partial program that computes the cost of buying an item at the deli. Save the program to your directory and do the following:

1. Study the program to understand what it does.

1. Add the import statements to import the DecimalFormat and NumberFormat classes.

1. Add the statement to declare money to be a NumberFormat object as specified in the comment.

1. Add the statement to declare fmt to be a DecimalFormat object as specified in the comment.

1. Add the statements to print a label in the following format (the numbers in the example output are correct for input of $4.25 per pound and 41 ounces). Use the formatting object money to print the unit price and total price and the formatting object fmt to print the weight to 2 decimal places.
