Hey, can someone help me, pls.

Question about the task

Maximum of entered numbers

Java Syntax, Level 4, Lesson 2

Resolved

I become an error on line 16 because "the variable wasn't initialised". Help me pls.

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 sc = new Scanner(System.in); int max = 0; int input = 0; while (true) { if (sc.hasNextInt()) { input = sc.nextInt(); max=(input%2==0&&input>max)?input:max; }else{ break; } } } }

There are no errors in this code on line 16, however there are some logical errors that need to be corrected: - The variable 'max' will calculate the highest integer as 0 in the case where all the entered even numbers are less than 0, or there are no other even numbers entered. For example, if I entered: 3, 7, -16, -2, -5 The correct value of 'max' should be -2 - another logical error is that the program should output the entered maximum number in the case that there are no even numbers entered. So if I entered 7,15, 1, 9 (no even numbers) it should output 15; however if I entered 7, 15, 2, 1, 9 it should output 2 because that is the maximum even number. - If I hit enter without entering anything that would also be considered "until something else is entered" and the program should stop reading integers. Also there needs to be a line that outputs the correct answer.
