I don't know what is wrong if everything doing good.

Question about the task

Summation

Java Syntax, Level 4, Lesson 3

Under discussion

I think everything is good? I don't understand what's wrong, I suppose that every step is allright.

package en.codegym.task.pro.task04.task0403; import java.util.Scanner; /* Summation */ public class Solution { public static int x = 0; public static void main(String[] args) { Scanner scanner = new Scanner(System.in); // Scanner lineScanner = new Scanner(System.in); boolean isContinue = false; while (!isContinue) { if (scanner.hasNextInt()) { int y = scanner.nextInt(); x += y; } else if (scanner.hasNextLine()){ String s = scanner.nextLine(); isContinue = s.equals("ENTER"); } } System.out.println(x); } }

was the static int 'x' already part of the starting code? If not then you need to put 'x' in the main method and remember not to use static variables in your code unless specified to. Put this code in the same file under the Solution class:

class Test {
    public static void main(String[] args) {
        ByteArrayInputStream test1 = new ByteArrayInputStream("5\n6\nENTER".getBytes());
        ByteArrayInputStream test2 = new ByteArrayInputStream("10\n-5\nENTER".getBytes());
        ByteArrayInputStream test3 = new ByteArrayInputStream("-100\n-8000\nENTER".getBytes());
        ByteArrayInputStream test4 = new ByteArrayInputStream("2\n2\nENTER".getBytes());
        InputStream save = System.in;
        String[] temp = new String[0];
        System.setIn(test1);
        Solution.main(temp);
        System.setIn(test2);
        Solution.main(temp);
        System.setIn(test3);
        Solution.main(temp);
        System.setIn(test4);
        Solution.main(temp);
    }
}

then run Test.main. The correct output should be: 11 5 -8100 4 However the output with your code is: 11 16 -8084 -8080
