Not Looping? (do - while) bad execution!

this program only asks me the first input

Code :

---

Enter The Max Value

---

then the whole program stops

Code :

---

public static void main(String[] args) {
 
        int count = 0;
 
        System.out.print("Enter The Max Value: ");
        int max = sc.nextInt();
 
        System.out.print("Which Value Do You Want To Display Even Or Odd?");
        String answer = sc.nextLine();
 
        do {
 
            count++;
 
            if (answer.equalsIgnoreCase("even")) {
 
                if (count % 2 == 0) {
 
                    System.out.println(count);
                }
            }
        }
        while (count != max);     
    }
}

There's no case to handle the odd numbers. Also, because of the funny implementation of nextInt(), it's not consuming the next line character when you input the max value.

Also, there is a much better method to print out odd/even numbers: use an if statement for even/odd, then iterate through all even/odd numbers up to max.

Code :

---

        System.out.print("Enter The Max Value: ");
        int max = sc.nextInt();
 
        System.out.print("Which Value Do You Want To Display Even Or Odd?");
        sc.nextLine(); // consume \n from above
        String answer = sc.nextLine();
 
        if ("even".equalsIgnoreCase(sc))
        {
                for (int i = 0; i < max; i+=2)
                {
                        System.out.println(i);
                }
        }
        else if ("odd".equalsIgnoreCase(sc))
        {
                for (int i = 1; i < max; i+= 2)
                {
                        System.out.println(i);
                }
        }
        else
        {
                System.out.println("You didn't enter even or odd. quiting.");
        }
