Question

Why does the Grade class which extends the School class give me an error when a new object is being created and the constructor is being called and passed the correct amount of parameters with the correct datatypes to the constructor?

I get the following warning in Netbeans using Java Se 6

cannot find symbol: Constuctor School();

package school;

public class School {
    String name;
    String location;
    int pupils;

    School(String name, String location, int pupils) {
        this.name = name;
        this.location = location;
        this.pupils = pupils;
    }

}

package school;
public class Grade extends School {
    School school = new School("Your Schools Name", "Your schools Location", 1700);
}

Answer 1

Constructors are not inherited. Your subclass needs its own constructor:

Grade(String name, String location, int pupils) {
    super(name, location, pupils);
}

Besides, this is very questionable design. A grade is not a school.
