System.out.println("Please input number" + i + ":");
int number = scanner.nextInt();
sum += number;
}
System.out.println("Sum of the number is" + sum);
double average = sum/numNumber;
System.out.println(" The average is" + average);
if (data> max){
max = data;
}
else if (data < min){
min = data;
}
else if (data >= 0 & data < max){
min = data;
}
else if (data<= 0 & data> min){
