HI all, I was looking at this program and noticed few things:
import static java.lang.System.out;
public class Employee {
private String name;
private String jobTitle;
public void setName(String nameIn) {
name = nameIn;
}
public String getName() {
return name;
}
public void setJobTitle(String jobTitleIn) {
jobTitle = jobTitleIn;
}
public String getJobTitle() {
return jobTitle;
}
public void cutCheck(double amountPaid) {
out.printf("Pay to the order of %s ", name);
out.printf("(%s) ***$", jobTitle);
out.printf("%,.2f\n", amountPaid);
}
}
import java.util.Scanner;
import java.io.File;
import java.io.IOException;
class DoPayroll {
public static void main(String args[])
throws IOException {
Scanner diskScanner =
new Scanner(new File("EmployeeInfo.txt"));
for (int empNum = 1; empNum <= 3; empNum++) {
payOneEmployee(diskScanner);
}
}
static void payOneEmployee(Scanner aScanner) {
Employee anEmployee = new Employee();
anEmployee.setName(aScanner.nextLine());
anEmployee.setJobTitle(aScanner.nextLine());
anEmployee.cutCheck(aScanner.nextDouble());
aScanner.nextLine();
}
}
And here's the text file

Right, so first thing: where are the calls to the getters? Surely they are implicitly called, but how? I don't see anywhere
getName()
and
getJobTitle()
?
And don't we need a third setter and getter for the thrid variable, the money?
Then the for loop:
for (int empNum = 1; empNum <= 3; empNum++) {
payOneEmployee(diskScanner);
}
We are running this loop 3 times because eachinstance of the new Employee class created has 3 variables associated with it (name, jobTitle and the money?)
thanks
