Question

I have a class that contains a few strings, as well as a few integer values. The program needs to use bubble sort to sort by a specific integer within called studentID.

The issue I’m coming across is accessing the variable properly. We are required to keep the variables within the class private, so the raw values aren’t directly accessible from anywhere other than inside the actual class.

I’ve got something like this set up

public class Student {
    // PRIVATE strings and ints

    public Student() {
        // set variables to text fields
    }

    public void bubbleSort() {
        int i, j, temp;

        for (i = (x-1); i >= 0; i--) {    
            for (j = 1; j <= i; j++) {    
                if(x[j - 1] > students[j]) {
                    temp = x[j - 1];
                    x[j - 1] = x[j];
                    x[j] = temp; 
                }
            } 
        }
    } 
}

For every occurrence of X, I need to have the value of myStudent.studentID. The bubble sort is meant to be implemented within the class, but I can’t figure out how to call it. With the needed fields set to private, I can find no way to pull the information to be sorted.

Answer 1

You use properties to expose private fields to the outside.

private string text = "";

public string Text
{
  get { return text; }
  set { text = value; }
}

If you aren’t allowed to do that, you should talk with your teacher, as interacting with the class isn’t possible then.
