java grade report homework assignment
<p>I am supposed to:</p>

<ol>
<li>create two constructors. a. query for student's names and three scores. b. take four arguments</li>
<li>write a method calculateAvg that calculates and sets average</li>
<li>write a method calculateGrade that calculates based on 90+=A, 80+=B, 70+=C, 60+=D, &lt;60=F</li>
<li>Write a method toString that displays a gradeReport with the a. name b. three scores on a single line c. average and letter grade</li>
<li>when the first constructor is used ensure that the scores are within 0-100. if not prompt again and explain why.</li>
<li>format the output to exactly two decimal places</li>
<li>format the output so that the scores are separated by tabs.</li>
</ol>

<p>I am not asking for this all to be done, but if you look at my code can you give me any leads on where I'm going wrong and what I might need to add?</p>

<pre><code>import java.text.DecimalFormat;
import java.util.Scanner;
public class GradeReport 
{
    String name, name1, name2;
    int score1, score2, score3;
    double average;
    char grade;
    public GradeReport()  //creates the first constructor
    {
        Scanner sc = new Scanner (System.in);

        System.out.println ("Enter student's first name: ");
        name1 = sc.nextLine();

        System.out.println ("Enter the student's last name: ");
        name2 = sc.nextLine();

        System.out.println ("Enter first grade: ");
        score1 = sc.nextInt();

        System.out.println ("Enter second grade: ");
        score2 = sc.nextInt();

        System.out.println ("Enter third grade: ");
        score3 = sc.nextInt();
    }
    public GradeReport (String name, int score1, int score2, int score3)
    {
    }
    public void calculateAverage()
    {
        average = ((score1 + score2 + score3) / 3);

        DecimalFormat fmt = new DecimalFormat ("0.###"); //to format average to 2 decimal places
    }
    public void calculateGrade()
    {
        if (average &gt;= 90)
            System.out.println("A");
        else if (average &gt;= 80)
            System.out.println("B");
        else if (average &gt;= 70)
            System.out.println("C");
        else if (average &gt;= 60)
            System.out.println("D");
        else
            System.out.println("F");
    }
    public String toString()
    {
        //System.out.println (name1, name2);
        String gradeReport = Double.toString(score1) + "\t," + Double.toString(score2)+ "\t," + Double.toString(score3);
        //String gradeReport = Double.toString(average);
        return gradeReport;
    }
