如何在输出中获取输入词？初学Java

Question

我试图在我的输出中找到出发地点，但我对如何去做感到困惑。我是否必须在顶部的 String 方法中声明它？

    int seconds1;

    int seconds2;

    int minutes;

    int hours;

    Scanner sc = new Scanner(System.in);

    System.out.println("Enter departure city: ");

    String departure = sc.nextLine();

    System.out.println("Enter arrival city ");

    String arrival = sc.nextLine();

    System.out.println("Enter time (in seconds) it takes to travel between: ");

    seconds1 = sc.nextInt();

    hours = (seconds1 % 86400) / 3600;

    minutes = ((seconds1 % 86400) % 3600) / 60;

    seconds2 = ((seconds1 % 86400) % 3600) % 60;

    // I am trying to get this to say "The time between + departure + and + arrival+is"

    System.out.println("The time to travel  between and  is "); 

    System.out.println(hours + " : " + minutes + " : " + seconds2);

  }

}

Answer 1

您可以指定departure和arrival变量，System.out.println()如下面的代码所示：System.out.println("The time to travel  between"+departure +" and"+arrival +"  is ");

Answer 2

你会有这个：System.out.println("The time to travel between " + departure + " and " + arrival + " is ");
