Question
In JAVA, Write a program that reads data from an input file and writes a report to an output file.
The input data will be veterinary data. The output will be a report of the cost of one visit to the vet for one pet. See below for both the input file format and the report format.
1) Report column specifications. Define the columns in the printf statements that generate the report such that they are wide enough to hold data at least as large as the data that appears in the sample input file below. All data in each column should be properly lined up
The name column should be left justified and the other columns should be right justified.
Ask the user to enter the name of both the input and output files. Whatever names they enter at the command line during execution should be used for input and output.
