# Object-Oriented Programming with Java, part II – Exercise 2

Write a number that asks user for input until the user inputs 0. After this, the program prints the average of the positive numbers (numbers that are greater than zero).

## My Code

### Main

``````import java.util.Scanner;

public class AverageOfPositiveNumbers {

public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);

int i = 0;
int total = 0;
while (true) {
int input = scanner.nextInt();
if (input == 0) {
break;
}
if (input > 0) {
total += input;
i++;
}
}
if (total == 0) {
System.out.println("Cannot calculate the average");
} else {
System.out.println((double) total / i);
}

}
}``````

## Model Code

### Main

``````import java.util.Scanner;

public class AverageOfPositiveNumbers {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

int count = 0;

int sum = 0;

while (true) {

int number = Integer.valueOf(scanner.nextLine());

if (number == 0) {

break;

}

if (number < 0) {

continue;

}

count = count + 1;

sum = sum + number;

}

if (count == 0) {

System.out.println("Cannot calculate the average");

} else {

System.out.println(1.0 * sum / count);

}

}

}``````
