I am working on this program in which im trying to gather information about certain things. But when i try to compile it says a variable is not found, even though it is clearly defined. Its not quite completely funciontal yet so... bare with it.

Also i am jsut learnign about inheritances so likely its a problem with the way its declared.

also i know there is a lot commented out, but i did that after realize that i think i did it wrong.

Its saying grad year cannot be found but all the other variable from the parent class work. Any Suggestions?

class HighSchool extends Project8Driver
{
public HighSchool()
{
int gradYear;
System.out.print("What year do you plan to graduate? ");
gradYear = scan.nextInt();
System.out.print("How many credits do you need to aquire before you can graduate? ");
int credLeft = scan.nextInt();
System.out.print("What did you score on the SAT? ");
int SAT = scan.nextInt();
System.out.print("How many AP credits do you have? ");
int apCred = scan.nextInt();

}

public String toString()
{
return "Name: " +name+ "\nAge: "+age+ "\nID: "+id+"\n Graduation year: " + gradYear;
}
