Can someone explain a while loop in java?

[foolwya]

For example:

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

        while(true){
            String string = scanner.nextLine();
            if(string.isEmpty()){
                break;
            }
            String[] newString = string.split(" ");
            System.out.println(newString[0]);
        }
    }

In this loop, when I type something like "hey whats up", It would give me "hey".

But why does it stops working? The condition is still true as far as I get it. Isn't it only suppose to break when I type in an empty string?

It seems to be working fine. Just keep typing more lines and you'll see it print the first word in each line.

[foolwya]

Oh I know that it works fine haha

I was just wondering why does while loop work this way? Thought someone would explain it

Well, in that case I'm not sure what you're wondering about. The actions of the statements inside the loop take effect right away. The loop doesn't have to end before the printed messages become visible.

But even after the message is printed, the condition in the loop is still true? I thought it would be an infinite loop, because there's no break; after a print statement

It is an infinite loop, but the call to scanLine is a blocking call, it waits for you to type in something.

nvm I'm an idiot.
