Question

Modification to be completed by group member 4:

In the processLineOfData method, write the code to handle case "M" of the switch statement such that:

• A Manager object is created using the firstName, lastName, salary, and bonus local variables. Notice that salary and bonus need to be converted from String to double. You may use parseDouble method of the Double class as follows:

              Double.parseDouble(salary)

• Call the parsePaychecks method in this class passing the Manager object created in the previous step and the checks variable.

                

• Call the findDepartment method on the company variable passing deptName.

                

• If a department is found, call the setDepartmentManager method on it passing the Manager object created in the first step.

Code:
