    Question How can I debug this code?

    import java.util.Scanner;

    public class AverageSix
    public void getGrades()
    Scanner input = new Scanner( System.in );

    System.out.println( "Please enter the number of students you wish to average" );
    int students2 = input.nextInt();

    int NumOfStudents = students2;
    int counter = 1;
    double total = 0, previousNumber = 0, newMaximum = 0, newMinimum = 0;

    while ( students2 != 0 )
    System.out.println( "Please enter a grade" );
    double givenNum = input.nextDouble();
    total = total + givenNum;

    if ( counter == 1 )
    previousNumber = givenNum;
    newMinimum = givenNum;
    } // end if

    if ( newMaximum < givenNum )
    newMaximum = maximum( previousNumber, givenNum );

    if ( newMinimum > givenNum )
    newMinimum = minimum( previousNumber, givenNum );

    previousNumber = givenNum;
    } // end while

    double average1 = average( total, NumOfStudents );

    System.out.printf( "The maximum: %.2f\nThe average: %.2f\nThe minimum: %.2f\n",
    newMaximum, average1, newMinimum);
    } // end method getGrades
    } // end class AverageSix

    public double average( double x, y );
    return x / y;
    } // end method average

    public double maximum( double x, double y )
    Math.max( x, y );
    } // end method maximum

    public double minimum( double x, int y )
    return min( x, y );
    } // end method minimum

    I don't understand exactly what you are asking. I use Netbeans and place break points wherever I need.

    Use an IDE (NetBeans, Eclipse) and step through during the execution of the code.

    If you are just beginning, I would not recommend using an IDE. Add some println's within your code to let you evaluate the code (variable values, conditionals, etc...). This is quite possibly one of the most valuable debugging tools
