Both files are posted,
Update the Employee class to facilitate sorting of
an ArrayList<Employee> list, grouping and ordering
the list using these criteria:
public class Person {
private String familyName;
private String givenName;
private int id;
public Person(String familyName, String
givenName, int id) {

setFamilyName(familyName);

setGivenName(givenName);
setId(id);
}
public Person() {
setFamilyName("");
setGivenName("");
setId(0);
}
public void setFamilyName(String familyName)
{
this.familyName =
familyName;
}
public void setGivenName(String givenName)
{
this.givenName =
givenName;
}
public void setId(int id) {
this.id = id;
}
public String getFamilyName() {
return familyName;
}
public String getGivenName() {
return givenName;
}
public int getId() {
return id;
}

@Override
public String toString() {
String fmt =
"Person[familyName=%s,givenName=%s,id=%d]";
String str =
String.format(fmt, familyName, givenName, id);
return str;
}
}
public class Employee extends Person {
private String title;
private String contractOrg;
public Employee(String familyName, String
givenName, int id, String title, String contractOrg) {
super(familyName, givenName, id);
setTitle(title);

setContractOrg(contractOrg);
}
public Employee() {
setTitle("");
setContractOrg("");
}
public void setTitle(String title) {
this.title = title;
}
public void setContractOrg(String
contractOrg) {
this.contractOrg =
contractOrg;
}
public String getTitle() {
return title;
}
public String getContractOrg() {
return contractOrg;
}
public String getEmployeeInfo() {
return title + " (" +
contractOrg + ")";
}
@Override
public String toString() {
String fmt =
"Employee[title=%s,contractOrg=%s]%s";
String str =
String.format(fmt, title, contractOrg, super.toString());
return str;
}
