:confused: merge/covert array Part II :confused:

I need to take all of the data in a double subscripted array, except for the first column, and add it into a new single subscripted array. I HAVE to do it by code, I cannot simply retype the data into the new array. I created the following as a test case and it works except for the fact that it throws an exception upon execution. I added test output to see where the problem is, but I am not finding it. I am sure it something very simple.
The error I get is:
java.lang.ArrayIndexOutOfBoundsException: 3
at ArrayCopyDemo.main[Compiled Code}
Any help will be appreciated,
Paul

public class ArrayCopyDemo {
  public static void main(String[] args) {
    
    int grades[][] = { { 2772, 126, 169, 194, 177 },
                       { 3375, 163, 188, 189, 185 },
                       { 4456, 171, 190, 186, 198 }                    };
    
    int students = grades.length;
    int count = 0;
    int length= (grades[0].length-1) + (grades[1].length-1) + (grades[2].length-1);
    
    int justGrades[] = new int[length];
    
    System.out.println("\n\nstudents =" + students);                //for test purposes
    System.out.println("justgrades.length =" + justGrades.length);  //for test purposes
    
    for (int row = 0; row <= students; row++)
    {
      System.out.println("-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=");   //for test purposes
      
      for (int grade = 1; grade <= ((grades[row].length)-1); grade++)
      {
        justGrades[count] = grades[row][grade];
        //test block
        System.out.println("Counter = " + count);
        System.out.println("Row = " + row);
        System.out.println("Grade# = " + grade);
        System.out.println("grade.row.length = " + grades[row].length);
        System.out.println("Grade = " + grades[row][grade]);
        System.out.println("justGrades[" + count + "] = " + justGrades[count]);
        //end test block
        count++;
      }
    }
    
    System.out.println(justGrades[11]); //for test purposes
  }
}

for (int row = 0; row <= students; row++)
What is the initial value of row? What is the final value of row? If students = 3, how many different values of row do you have in this loop?

BINGO! Thanks, I knew it was something like that, but after staring at it a while it was all going fuzzy.
You know, if arrays start their cointing at 0, why does array.length start with 1? Seems a bit inconsistant to me.

Because it is legal and possible to have an empty array -- an array whose length is 0:
String[] none = new String[0];

Paul,
Please note that you can preserve the formatting of code by surrounding it with the [code] and [/code] UBB Tags. It can make it a lot easier to read.
