Scanner sc = new Scanner(System.in); //scanner

int count = 0; //to store the number of valid gpas

System.out.println("Enter the GPA values one per line:");

double gpa = sc.nextDouble();

double sum = 0;

while(gpa >= 0){ //if gpa is non negative

count++; //increment the number of valid gpa

sum = sum + gpa; // add the gpa to sum

gpa = sc.nextDouble();

}

System.out.println("The number of valid GPAs entered: "+count);

System.out.println("The sum of the GPAs: "+sum);

System.out.println("The average GPA: "+sum/count);

}

}

OUTPUT SNIPPET:

Enter the GPA values one per line: 5 5.5 6.5 8.2 3 The number of valid GPAs entered: 4 The sum of the GPAs: 25.2 The average GPA: 6.3
