Trying to figure out the math.

Question about the task

Under discussion

I'm trying to figure out small parts of the code I'll need for this task. I'm currently working with making sure the number is even. But there's something wrong and I don't know what it is, when I run the code with the example inputs it prints 9 & 4, one is even and one isn't, but it should only print one or the other if everything is correct and I just have it backwards, so what's wrong?

The program must read integers from the keyboard until something else is entered, such as a string or a character. Display the maximum even number entered. If several numbers are entered, you must display any of them.

Example input:

Example output:
8

Requirements:

The program should read numbers from the keyboard.
The program should display a number on the screen.
The program should display the maximum even number of the integers entered.
If several maximum even numbers are entered, then you need to display any one of them.
If there is no even number among the entered characters, or only one non-numeric character is entered, then display the minimum possible value for an int.
You need to read data from the keyboard in a while loop.

package en.codegym.task.pro.task04.task0408; import java.util.Scanner; /* Maximum of entered numbers */ public class Solution { public static void main(String[] args) { //write your code here Scanner console = new Scanner(System.in); int max = -2000000000; while (console.hasNextInt()) { if (console.nextInt() % 2 == 0) { System.out.println(console.nextInt()); } } //System.out.println(max); } }

Scanner console = new Scanner(System.in);

if (console.hasNextInt()) { //checking if there is a next int in the stream
    // if yes, print it
    System.out.println("1: " + console.nextInt());
    // now waiting for a second input. This will throw an exception if it is not of the
    // expected type
    System.out.println("2: " + console.nextInt());
}
