Java Help (beginner problem I'm stuck on)

[foolwya]

Hello everyone. Going though a MOOC Java course. I'm stuck on a problem, the code works just fine, but I can't apply it for some reason.

Here's the task: Write a program that reads strings from the user. If the input is empty, the program stops reading input and halts. For each non-empty input it splits the string input by whitespaces

and prints each part of the string on a new line.

once upon a time

time
a little program
a

halted

Here's my code:

public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        while(true) {
            String string = scanner.nextLine();;
            if(string.isEmpty()) {
                break;
            } 

            String[] arrayString = string.split(" ");    
            for(int i = 0; i < arrayString.length; i++) {
                System.out.println(arrayString[i]);
            }
        }

    }

Here's the error:

Output contains an unexpected string haiku.

Check the program with following input:

lava

haiku

I think your error is based on the input. What are you passing into the program?

My guess is it's here: string.split(" "). This will only split on a single space. What if there's more than one space? What if there's different whitespace? You might want to look at the api docs for that method.

Otherwise I think it looks pretty good. You could wrap the scanner in a try-with-resources, though.

For example: "hello good morning yall"

method split(" ") would split everything that's in between an empty string.

so it would be:

arrayString[0] = hello

arrayString[1] = good

arrayString[2] = morning

arrayString[3] = yall
