java - 如何通过另一个构造函数添加到数组列表？

Question

所以我需要尝试通过我的驱动程序类中的这个构造函数添加到我的资格数组列表中。我正在使用扫描仪通过键盘获取所有输入我是一名初学者程序员，我认为这只是一些基本的东西。

public class Driver {

private Scanner sc = new Scanner(System.in);
private Doctor doctor;
private Qualification qualifications;

System.out.println("Enter doctors name: ");
                    sc.nextLine();
                    String name = sc.nextLine();
                    System.out.println("Enter doctors date of birth");
                    String dob = sc.nextLine();
                    System.out.println("Enter doctors gender");
                    String gender = sc.nextLine();
                    System.out.println("Enter doctors address");
                    String address = sc.nextLine();
                    System.out.println("Enter doctors contact number");
                    String contactNumber = sc.nextLine();
                    System.out.println("Was the doctor qualified in Ireland?");
                    boolean qualifiedInIreland = sc.nextBoolean();
                    System.out.println("Add doctor qualifications");



Doctor doctor1 = new General(name, dob, gender, address,contactNumber, qualifiedInIreland, <Qualification> qualifications);
                    med1.addDoctor(doctor1);

Answer 1

med1 对象属于哪种类型？请提供完整代码

您需要将资格存储在 Arraylist 中，然后将资格的 Arraylist 传递给 Doctor 构造函数。

尝试添加这个

ArrayList<String> qualifications = new ArrayList<String>();
System.out.println("Add doctor qualifications");
while(sc.hasNext){
        qualifications.add(sc.nextLine());  
}

然后

Doctor doctor1 = new General(name, dob, gender, address,contactNumber, qualifiedInIreland, qualifications);
