Thread: 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 );

students2--;
counter++;
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.
