java - 如何在不同的类中获取2个ArrayList？

Question

我有两个类Student和Worker。我定义了两个 ArrayList 并为每个类都有一个 getter。

Worker 类:

private List<Worker> WorkerList = new ArrayList<Worker>();

public List<Worker> getWorkerList() {
    return WorkerList;
}

public Worker(String first, String last, float WeekSalary,
        float WorkingHours) {
    super(first, last);
    this.setWeekSalary(WeekSalary);
    this.setWorkingHoursPerDay(WorkingHours);
    // TODO Auto-generated constructor stub
}

学生类(class):

private List<Student> StudentList = new ArrayList<Student>();

public Student(String first, String last, int gradeValue) {
    super(first, last);
    this.setGrade(gradeValue);
}

public List<Student> getStudentList() {
    return StudentList;
}

这里的问题是如何从另一个类获取这两个ArrayList？例如MergeClass？

Answer 1

只需调用MergeClass中的getter方法即可。你可以有这样的东西:

Worker w = new Worker();
Student s = new Student();
List<Worker> workerList = w.getWorkerList();
List<Student> studList = s.getStudentList();
