How do I output this array of test grades?

Question

I am creating an array to print test grades and their cutoff. However, every time my output is this:

Grade@9c7e21
Grade@6194f8
Grade@258f60
Grade@418c57
Grade@1937e44
Grade@193a307
Grade@1a6cfa1
Grade@5b7a7
Grade@950d76
Grade@dceda6
Grade@102f6c0
Grade@681b92

What should I change so the output is the test grades and cutoffs?

Here are my 2 classes:

public class Grade
{
  private String grades;
  private int cutoff;
  //-----------------------------------------------------------------
  // Stores the possible grades and their numeric lowest value.
  //-----------------------------------------------------------------
  public Grade (String average, int lowvalue)
  {
    grades = average;
    cutoff = lowvalue;
  }
  //-----------------------------------------------------------------
  // Returns the possible grades and their lowest numeric value.
  //-----------------------------------------------------------------
  public String getGrades (String grades, int cutoff)
  {
    return grades + "\t" + cutoff;
  }
}

Driver class:

public class GradeRange
{
//-----------------------------------------------------------------
// Stores the possible grades and their numeric lowest value,
// then prints them out.
//-----------------------------------------------------------------
  public static void main (String[] args)
  {
    Grade[] score = new Grade[12];
    score[0] = new Grade ("A", 95);
    score[1] = new Grade ("A-", 90);
    score[2] = new Grade ("B+", 87);
    score[3] = new Grade ("B", 83);
    score[4] = new Grade ("B-", 80);
    score[5] = new Grade ("C+", 77);
    score[6] = new Grade ("C", 73);
    score[7] = new Grade ("C-", 70);
    score[8] = new Grade ("D+", 67);
    score[9] = new Grade ("D", 63);
    score[10] = new Grade ("D-", 60);
    score[11] = new Grade ("F", 0);
    for (int index = 0; index < score.length; index++)
      System.out.println (score[index]);
  }
}

`score[index]` will be an instance of a grade object. Try overriding the toString method on your Grade object: http://stackoverflow.com/questions/10734106/how-to-override-tostring-properly-in-java — Evan Trimboli, Dec 06 '16 at 00:28
create a toString method that returns same thing as getGrades and call that on the array item — Nkosi, Dec 06 '16 at 00:28
@Nkosi A 95 A- 90 B+ 87 B 83 B- 80 C+ 77 C 73 C- 70 D+ 67 D 63 D- 60 F 0 — Michael Kelley, Dec 06 '16 at 00:28

add toString method to the Grade class

public String toString() { 
   return grades + "\t" + cutoff;
}

and use it in the for loop

for (int index = 0; index < score.length; index++)
    System.out.println (score[index].toString());
