Question

Suppose that a class, Employee, is defined as follows:

class Employee {
  String lastName;
  String firstName;
  double hourlyWage;
  int yearsWithCompany;
}

Suppose that the data of about 100 employees is already stored in an array:

Employee[] employeeData = new Employee[100];

1. Write a code segment that will output the first name, last name, and hourly wage of each employee who has been with the company for 20 years or more.
2. Write two versions of the code segment, (a) one that uses a regular for loop, and (b) one that uses a for-each loop.

Answer 1

Thanks for the question.

Below is the code you will be needing Let me know if you have any doubts or if you need anything to change.

Thank You !!

==============================================================================================

Employee[] employeeData = new Employee[100];


// (a) one that uses a regular for loop

for (int i = 0; i < employeeData.length; i++) {

    if (employeeData[i].getYearsWithCompany() >= 20) {
        System.out.println("First Name: " + employeeData[i].getFirstName() +
                ", Last Name: " + employeeData[i].getLastName() +
                ", Hourly Wage: $" + employeeData[i].getHourlyWage());
    }

}

// (b) one that uses a for-each loop.

for (Employee employee : employeeData) {
    if (employee.getYearsWithCompany() >= 20) {
        System.out.println("First Name: " + employee.getFirstName() +
                ", Last Name: " + employee.getLastName() +
                ", Hourly Wage: $" + employee.getHourlyWage());
    }
}
