smallest and largest of the inputs

Question

I was assigned to write a program that read a sequence of integer inputs and print -the smallest and largest of the inputs -and the number of even and odd inputs

I f

Answer 1

Keep track of the smallest value in the same manner.

public static void main(String args[])
{
    Scanner a = new Scanner (System.in);
    System.out.println("Enter inputs (This program calculates the largest and smallest input):");

    double firstInput = a.nextDouble();
    double largest = firstInput;
    double smallest = firstInput;
    while (a.hasNextDouble())
    { 
        double input = a.nextDouble();
        if (input > largest)
        {
            largest = input;
        }
        if (input < smallest)
        {
            smallest = input;
        }
    }

    System.out.println("Largest: " + largest);
    System.out.println("Smallest: " + smallest);
    }
}

Answer 2

The simplest solution would be use something like Math.min and Math.max

double largest = a.nextDouble();
double smallest = largest;
while (a.hasNextDouble()) {
    double input = a.nextDouble();
    largest = Math.max(largest, input);
    smallest = Math.min(smallest, input);
}

Answer 3

double largest = a.nextDouble();
double smallest = largest;
while (a.hasNextDouble()) {
    double input = a.nextDouble();
    if (input > largest) {
        largest = input;
    }
    if (input < smallest) {
        smallest = input;
    }
}
