I need a little help...

Question about the task

Resolved

I feel a little embarrassed to ask, due to the simplicity of the problem, yet my code isn't working and I can't figure out why. It's printing the opposite of what I want it to print. I ask it to print a string 4 times, it prints it 2 times, and vice-versa. Can anyone help me. Thank you!

In this task, you need to:

Use the keyboard to read a string and a number (number variable) that is greater than 0 and less than 5.
Display the string number times using a do-while loop. Display each value on a new line.

If the value read in for the number variable is less than or equal to 0 or greater than or equal to 5, then the entered string must be displayed once.

Example input:
abc 2

Example output:
abc abc

Requirements:

The program should read data from the keyboard.
The program should display data on the screen.
The program should display the string number times.
The program should display the string once if number is less than or equal to 0 or greater than or equal to 5.
The program must use a do-while loop.

package en.codegym.task.pro.task04.task0414; import java.util.Scanner; public class Solution { public static void main(String[] args) { Scanner input = new Scanner(System.in); String a = input.nextLine(); int b = input.nextInt(); do { System.out.println(a); b++; } while (b >= 0 && b <= 5); } }

useful

1. Condition in line 17 should be with 'or' not 'and'. 2. Use corrected condition to make a brake statement in the do-loop. 3. Introduce int count variable and use it in the loop instead of b variable. 4. Use b and count variables to rewrite while statement.

I'm still a newbie to coding, and I can admit that...

solution

Probably everyone who's coding feels embarrassed at least once an hour. And it doesn't matter if you're new to programming or if you're a veteran coder. If you do not like that feeling then the job is nothing for you ;) And to your question. I just think you missunderstood the task. It should output the the entered string n times if n is between 1 and 4, if n is outside that range the string should be output once. But I also may be wrong. The description not always is the best. So I'd try smth like this:

do
{
    System.out.println(a);
} while (b > 1 && b-- < 5);

or you introduce a counter variable as already suggested
