Cannot resolve symbol?

[Seral1969]

Hi, I'm new to Java...

I've been trying to get one of my professor's examples to work...

He says that the code is fine, but I keep getting 4 "cannot resolve symbol" errors when I try to compile the ShowStudent.jav a file...

The code for the Student class and ShowStudent program are listed below...

PLEASE HELP!!!

// Student.java
// creates a class to store info about a student
 
class Student
{
    // the private data members
    private int IDnumber;
    private int hours;
    private int points;
 
    // constructor added in last part of project
    Student()
    {
        IDnumber = 77375;
        points = 12;
        hours = 3;
    }
    // end of constructor
 
    // the public get and set methods
    public void setIDnumber(int number)
    {
        IDnumber = number;
    }
 
 
    public int getPoints()
    {
        return points;
    }
 
    // methods to display the fields
    public void showIDnumber()
    {
        System.out.println("ID Number is: " + IDnumber);
    }
 
    public void showHours()
    {
        System.out.println("Credit Hours: " + hours);
    }
 
    public void showPoints()
    {
        System.out.println("Points Earned: " + points);
    }
 
    public double getGradePoint()
    {
        return (double)points / hours;
    }
 
}
 
 
 
// ShowStudent.java
// client to test the Student class
 
class ShowStudent
{
    public static void main (String args[])
    {
        student pupil = new student();
 
 
        pupil.showIDnumber();
        pupil.showPoints();
        pupil.showHours();
        System.out.println("The grade point average of the studnet created by constructor is "
            + pupil.getGradePoint()+"\n\n");
 
        Student s2 = new Student();
        s2.setIDnumber(12345);
        s2.setPoints(66);
        s2.setHours(20);
        s2.showIDnumber();
        s2.showPoints();
        s2.showHours();
        System.out.println("The grade point average of another student is "
            + s2.getGradePoint()+"\n");
 
    }
}

In ShowStudent, you say:

student pupil = new student();

but the Student class is spelled with a capital S, like you used for s2:

Student s2 = new Student();

The compiler is looking for a separate class named student, which doesn't exist.

[Seral1969]

I changed the the S to uppercase, but I still get the same errors...

[Ganon11]

Can you copy/paste the exact errors? Put them between [code] tags so they are easier to read, please.

[Seral1969]

Here is the uptated ShowStudent.jav a file...

There are no changes to the Student.java file...

I have a screenshot of the error, but don't know how to attach it...

// ShowStudent.java
// client to test the Student class
 
public class ShowStudent
{
    public static void main (String args[])
    {
        Student pupil = new Student();
 
 
        pupil.showIDnumber();
        pupil.showPoints();
        pupil.showHours();
        System.out.println("The grade point average of the studnet created by constructor is "
            + pupil.getGradePoint()+"\n\n");
 
        Student s2 = new Student();
        s2.setIDnumber(12345);
        s2.setPoints(66);
        s2.setHours(20);
        s2.showIDnumber();
        s2.showPoints();
        s2.showHours();
        System.out.println("The grade point average of another student is "
            + s2.getGradePoint()+"\n");
 
    }
}

[Seral1969]

I have set comments to the problem areas...

// ShowStudent.java
// client to test the Student class
 
public class ShowStudent
{
    public static void main (String args[])
    {
        Student pupil = new Student();// 2 cannot resolve sybmol... points to 'S' in Student 
 
 
        pupil.showIDnumber();
        pupil.showPoints();
        pupil.showHours();
        System.out.println("The grade point average of the studnet created by constructor is "
            + pupil.getGradePoint()+"\n\n");
 
        Student s2 = new Student();// 2 cannot resolve sybmol points to 'S in Student
        s2.setIDnumber(12345);
        s2.setPoints(66);
        s2.setHours(20);
        s2.showIDnumber();
        s2.showPoints();
        s2.showHours();
        System.out.println("The grade point average of another student is "
            + s2.getGradePoint()+"\n");
 
    }
}

Now we're getting somewhere.

It looks like ShowStudent can't find the Student class - are they in the same folder?

If you can't get it to work, try copying/pasting the main into the Student class - that way, you're only working with one file, and there shouldn't be any unresolved errors.

[Seral1969]

Yes...

Both are in C:\Error...

[Seral1969]

The exercise says that I have to use two files...

I've even set the Student class to public...

No dice...

[Ganon11]

Try compiling Student.java first? Other than that, I don't know how to help you.
