// int payments=0;
String inputDocument = ("src/Employees.txt");
FileInputStream is = new FileInputStream(inputDocument);
Reader iD = new InputStreamReader(is);
BufferedReader buf = new BufferedReader(iD);
String inputLine;
while ((inputLine = buf.readLine()) != null) {
String[] lineParts = inputLine.split(",");
String email = (lineParts[7]);
int EmpNo = Integer.parseInt(lineParts[0]);
String type = lineParts[10];
int PostalCode = Integer.parseInt(lineParts[5]);
int phone = Integer.parseInt(lineParts[6]);
int DeptNo = (short) Integer.parseInt(lineParts[8]);
double Salary;
int card = (short) Integer.parseInt(lineParts[10]);
int emptype = 0;
int hours=Integer.parseInt(lineParts[11]);
if (type.equals("FULL TIME")) {
emptype = 1;
} else if (type.equals("SELLER")) {
emptype = 2;
} else {
emptype = 3;
}
/**

* (fulltime=1, salesman=2, parttime=3)
*/
switch (emptype) {
case 1:
Salary = Double.parseDouble(lineParts[10]);
emp.add(new FullTime(lineParts[1], lineParts[2], EmpNo,
lineParts[3],
lineParts[4], PostalCode, phone,
email, DeptNo, card, Salary,hours, type));
i++;

public void addEmployee(Employee emplo) {
emp.add(emplo);
}
public ArrayList<Employee> getArray() {
return emp;
}
public void getOption1() {
ArrayList<Employee> employee = getArray();
JTable table = new JTable();
DefaultTableModel model = new DefaultTableModel();
table.setModel(model);
model.setColumnIdentifiers(new String[]{"Code", "First Name", "Last Name", "Address", "City", "Postal Code", "Phone", "Email",
"Dept Code", "Salary", "Time Card", "Hours"});
for (Employee current : employee) {
model.addRow(new Object[]{current.getempCode(), current.getfirst(), current.getlast(),
current.getaddress(), current.getcity(), current.getpostalCode(),
current.gettelephone(), current.getemail(), current.getdep(),
current.getsalary(), current.getcardcode(), current.getHours()
});
}
table.setPreferredScrollableViewportSize(new Dimension(500, 50));
table.setFillsViewportHeight(true);
JScrollPane scrollPane = new JScrollPane(table);
add(scrollPane);
setVisible(true);
table.revalidate();
