如何在java中退出scanner.hasNextLine()循环

import java.util.Scanner;

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

        while (scanner.hasNextLine()) {
            String line = scanner.nextLine();
            System.out.println("输入的内容是：" + line);

            // 判断是否需要退出循环
            if (line.equals("exit")) {
                break;
            }
        }

        scanner.close();
    }
}
