Exercise
Use a StreamTokenizer or StringTokenizer in order to parse a simple ASCII Stream from the following file: “employee.db”, which contains records of employees. The fields are FirstName, LastName, Department and Salary, and are separated by the delimiter “:”. Every line in the file contains information for one employee only. For every employee, create an employee object (from an appropriate Employee Class), store in it the Strings read from the file, and add all the employee objects to a Vector. Finally, write some methods to allow a user to gather information about the employees that exist, e.g “Who’s the most well-paid employee” and “retrieve all the employees that work in the Accounting Department” etc.
