PreQuiz 2 - Spring 2006
Here's the Student.java class that we created in class.
public class Student extends Person {
private String school;
private int schoolID;
public Student(String someName){
super(someName); // Must be the first line
this.defaultSchool();
}
public Student(String someName, int someID){
super(someName,someID);
this.defaultSchool();
}
public String getSchool(){
return this.school;
}
public void setSchool(String someSchool,int someID){
this.school = someSchool;
this.schoolID = someID;
}
public void defaultSchool(){
this.school = "Gwinnett College";
}
public String toString(){
return super.toString()+". And I'm a student at "
+this.getSchool()+" and my school ID is "+this.schoolID;
/*return "I'm a student at "
+this.getSchool()+" and my school ID is "+this.schoolID;*/
}
public void greet(){
super.greet();
System.out.println("Go away -- I'm late for class! I'm a student at "
+this.getSchool());
}
public void countDownFrom(int endNumber){
System.out.println("Counting..."+endNumber);
if (endNumber == 1)
{return;}
countDownFrom(endNumber-1);
}
}
Write a new constructor so that we can create students with a Name, ID, School, and School ID.
Comments, questions, and answers!
public Student(String someName, int someID, String school, int schoolID){
super(someName,someID);
this.setSchool(school, schoolID);
}
So, we don't have to declare the 2 new variables, since they are already declared before the constructors,
and the superclass (Person) already sets name and id, so all we have to do is add the 2 input parameters and
call setSchool().
My question is this:
Traditionally, variables are local to functions... Does this hold true to the constructor?–
In other words, can I name 2 of my inputs String school and int schoolID in a constructor? It seems reasonable...
But I want to be sure they don't refer to the 2 defined in the class...
