1.Department类

public class Department {       private String departName;    private List<Employee> empList;       public Department() {          }      public Department(String departName, List<Employee> empList) {       super();       this.departName = departName;       this.empList = empList;    }      @Override    public String toString() {       return "Department [departName=" + departName + ", empList=" + empList             + "]";    }      public String getDepartName() {       return departName;    }      public void setDepartName(String departName) {       this.departName = departName;    }      public List<Employee> getEmpList() {       return empList;    }      public void setEmpList(List<Employee> empList) {       this.empList = empList;    }   }

 

2.Employee类

public class Employee {       private String empName;    private Address address;    private double salary;      public Employee() {          }      public Employee(String empName, Address address, double salary) {       super();       this.empName = empName;       this.address = address;       this.salary = salary;    }      public double getSalary() {       return salary;    }      public void setSalary(double salary) {       this.salary = salary;    }      public String getEmpName() {       return empName;    }      public void setEmpName(String empName) {       this.empName = empName;    }      public Address getAddress() {       return address;    }      public void setAddress(Address address) {       this.address = address;    }      @Override    public String toString() {       return "Employee [empName=" + empName + ", address=" + address + "]";    } }

 

3.Address类

public class Address {       private String country;    private String province;    private String city;    private String street;       public Address() {          }      public Address(String country, String province, String city, String street) {       super();       this.country = country;       this.province = province;       this.city = city;       this.street = street;    }      public String getCountry() {       return country;    }      public void setCountry(String country) {       this.country = country;    }      public String getProvince() {       return province;    }      public void setProvince(String province) {       this.province = province;    }      public String getCity() {       return city;    }      public void setCity(String city) {       this.city = city;    }      public String getStreet() {       return street;    }      public void setStreet(String street) {       this.street = street;    }      @Override    public String toString() {       return "Address [country=" + country + ", province=" + province             + ", city=" + city + ", street=" + street + "]";    }    }

 

4.GetData类

public class GetData {       public static List<Department> getDepartList() {       List<Department> departList = new ArrayList<>();             List<Employee> empList = new ArrayList<>();             for(int i = 1; i <= 20; i++) {          Employee employee = new Employee("emp"+String.format("%02d", i), new Address("country"+String.format("%02d", i), "prov"+String.format("%02d", i), "city"+String.format("%02d", i), "street"+String.format("%02d", i)),i*100.00);          empList.add(employee);       }             Department department01 = new Department("depart01", empList.subList(0, 4));       Department department02 = new Department("depart02", empList.subList(4, 8));       Department department03 = new Department("depart03", empList.subList(8, 12));       Department department04 = new Department("depart04", empList.subList(12, 16));       Department department05 = new Department("depart05", empList.subList(16, 20));             departList.add(department01);       departList.add(department02);       departList.add(department03);       departList.add(department04);       departList.add(department05);             return departList;    }      }
