B.
Passes the Employee variable (emp) to EmpFrame's constructor

EmployeeApp's executable statements should look like the following:
package
c3;
public class
EmployeeApp {
public static void
main(String[] args) {
Employee emp =
new
Employee(
new
String("Mary Worker"));
EmpFrame ef =
new
EmpFrame(emp);
}
}
2.
Save the EmployeeApp source code and verify there are no errors.
The following steps all concern changes to the Employee class source code:
3.
Delete the two import statements.
4.
Remove the following statement from the Employee constructor:
this
.displayName();
5.
Delete the displayName method.
We want to define the
String
empName as a property. As a reminder, the steps for defining a property are:
A.
Create a private variable
B.
Define a getter method to return the private variable value
C.
Define a setter method to:
accept a value for the private variable
validate the value
if the value is valid, set the private variable to the value passed to the setter method
For simplicity's sake, we will not define any edits to validate the data.
6.
Change the
String
empName to a private variable.
7.
Add a public setName method that:
A.
Returns void
B.
Accepts a
String
variable called name as a parameter
C.
Sets the private variable empName to name
