Java Program

This is an example of how to read a record from a comma delimited text file and split out the individual fields in each record. The “items.txt” file has records that contain the following fields:

· itemNumber, numeric identification number (int)

· description, text description of item (String)

· quantity, number of items of this type (int)

· unitCost, value of each item (double)

To use a comma (,) as the delimiter, File file = new File("C:/Data/items.txt"); // Create a Scanner object for this file.

Scanner input = new Scanner(file); input.useDelimiter(",");

You can then read a record and split it into separate fields, separated by commas like this:

while (input.hasNext()) {

String record = input.nextLine();

String tokens[] = record.split(",");

int itemNumber = Integer.parseInt(tokens[0]);

String description = tokens[1];

int quantity = Integer.parseInt(tokens[2]);

double unitCost = Double.parseDouble(tokens[3]);
