Hi, I am having a problem overriding methods in a subclass when they contain private methods from the master class. The is the master:
package blabla;
public class Person
{
private String firstName;
private String secondName;
private String familyName;
public Person()
{
firstName = "";
secondName = "";
familyName = "";
}
/**
* Parameter constructor
*/
public Person(String firstName, String secondName, String familyName)
{
this.firstName = firstName;
this.secondName = secondName;
this.familyName = familyName;
}
public String getFirstName()
{
return firstName;
}
public void setFirstName(String setFName)
{
firstName = setFName;
}
public String getSecondName()
{
return secondName;
}
public void setSecondName(String setSName)
{
secondName = setSName;
}
public String getFamilyName()
{
return familyName;
}
public void setFamilyName(String setFaName)
{
familyName = setFaName;
}
public static void testClassMethod()
{
System.out.println("The class method in Person");
}
public void print()
{
String first = getFirstName();
String second = getSecondName();
String family = getFamilyName();
System.out.println(first + " " + second + " " + family);
}
}
And this is the sub:
package blabla;
public class Student extends Person
{
private int facultyN;
public Student()
{
super();
facultyN = 0;
}
public Student(String firstName, String secondName, String familyName, int facultyN)
{
super(firstName, secondName, familyName);
this.facultyN = facultyN;
}
public int getFacultyN()
{
return facultyN;
}
public void setFacultyN(int setFN)
{
facultyN = setFN;
}
/*
* Overriding get/set methods
*/
@Override
public String getFirstName()
{
return firstName;
}
@Override
public void setFirstName(String setFName)
{
firstName = setFName;
}
@Override
public String getSecondName()
{
return secondName;
}
@Override
public void setSecondName(String setSName)
{
secondName = setSName;
}
@Override
public String getFamilyName()
{
return familyName;
}
@Override
public void setFamilyName(String setFaName)
{
familyName = setFaName;
}
@Override
public void print()
{
super.print();
int faculty = getFacultyN();
System.out.println("Faculty number: " + faculty);
}
}
Typing "protected" instead of "private" before the three String variables firstName, secondName and familyName makes it working, however what is the other solution when I leave them "private"? What should I type where I am overriding them in the subclass? Thanks.
