Hello guys !

I need some help with my Java Assignment ...

Assignment: http://screencast.com/t/NmLcx7OlA

I'm stuck from the begging until the c part.

I have no idea how to do a loop that reads every line from a file and how do I take those fields and add them into a Object ?

Thank you for your help !!!

It sounds like you need to reference lectures, slides, or your textbook. Most professors (I've yet to encounter one) don't just assign something without having a lecture on it.

Use a while loop and a scanner to read the file and save the input from the file in an array like this..

 while( scanner.hasNextLine() ) 
       
        String line[]  = scanner.nextLine(); 
        String x = line[0];
        .........
        //and then to create an object with the input
        Object ob = new Object(x);

I manage to do it like this:

String name1 = s.next();
String name2 = s.next();
String fullName = name1 + " " + name2;
int id = s.nextInt();
double rate = s.nextDouble();
double workHours = s.nextDouble();

The thing is that rate and workHours has all the values stored in them, I don't see how I can do this:

a. The total gross pay for all employees.
b. The total number of hours worked by all employees

The teacher doesn't want that we use Arrays ...

well if i understand well ..
a. You have to create a local variable to sum the total gross pay.. int sum = sum + grosspay;
b. You have to do the same int totalHours = totalHours + workHours;

Create an employee object for each entry read from your scanner and add it to a list. After you're done reading the file, you can iterate over the list and sum up all of the hours and pay.

ArrayList<Employee> payroll = new ArrayList<Employee>();

while(s.hasNextLine()) {
    String name1 = s.next();
    String name2 = s.next();
    String fullName = name1 + " " + name2;
    int id = s.nextInt();
    double rate = s.nextDouble();
    double workHours = s.nextDouble();

    payroll.add( new Employee(fullName, id, rate, workHours) );
}
