Question

(JAVA) I need to write an accessor method for the employeeDatabase field. The method is supposed to be named getEmployeeDatabase() and have a return type of Hashmap<Integer,Employee>. I have also included the test case below that is being used for this code to see if it works properly

private HashMap<Integer, Employee> employeeDatabase; public CompanyO f Scanner employeeDatabasepopulateEmployeeDatabase(keyboard) keyboard - new Scanner(System.in); public static void main(String[ args) private HashMap<Integer, Employee> populateEmployeeDatabase(Scanner keyboard) int numobjects -keyboard.nextIntO; String words HashMap <Integer, Employee mapnew HashMap<>); keyboard.nextLine); forCint i< numObjects; ++i) words-keyboard.nextLineO.split(","); map.put(i, new Employee(i, words[0], Double.parseDouble(words[1])); return map;

Answer 1

import java.util.HashMap;
import java.util.Scanner;

public class Company {

    private HashMap<Integer, Employee> employeeDatabase;

    public Company() {
        Scanner keyboard = new Scanner(System.in);
        employeeDatabase = populateEmployeeDatabase(keyboard);
    }

    // accessor method for the employeeDatabase field
    public HashMap<Integer, Employee> getEmployeeDatabase() {
        return employeeDatabase;
    }

    private HashMap<Integer, Employee> populateEmployeeDatabase(Scanner keyboard) {
        int numObjects = keyboard.nextInt();
        String words[];
        HashMap<Integer, Employee> map = new HashMap<>();
        keyboard.nextLine();
        for(int i = 0; i < numObjects; ++i) {
            words = keyboard.nextLine().split(",");
            map.put(i, new Employee(i, words[0], Double.parseDouble(words[1])));
        }
        return map;
    }

}
