【问题描述】：

我正试图在我的输出中找到出发地，但我对如何做到这一点感到困惑。我必须在顶部的 String 方法中声明它吗？

    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);
  }
}

几乎和你在下一行所做的时间一样（小时、分钟、秒2）

【解决方案1】：

你会得到这个：

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

请看-

package com.jap.falcon;

import java.util.Scanner;

public class Problem2 {
    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        int seconds1;
        int seconds2;
        int minutes;
        int hours;

        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;

        System.out.println("The time to travel  between "+ departure +" and "+arrival+" is "); // I am trying to get this to say "The time between
                                                                    // + departure + and + arrival + is"
        System.out.println(hours + " : " + minutes + " : " + seconds2);
    }
}

【解决方案3】：

您可以在System.out.println() 中指定departure 和arrival 变量，如下代码所示：

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

【解决方案4】：

您要问的是所谓的串联。

作为基线，连接是指对字符串进行“添加”。

String a = "Hello, " + "World!";
System.out.println(a);            // Prints "Hello, World!"

这也可以在内打印语句中完成。

System.out.println("Hello, " + "World!");

由于您的出发地点和目的地都已经是字符串的形式，它可能看起来像这样：

System.out.println("The time between " + departure + " and " + arrival + " is:");

对于 Java，您的 departure 和 arrival 变量已经是字符串，因此它只会将它们插入到您预先输入的字符串之间。不要忘记在字符串中包含空格（在“between”之后、“and”的两侧以及“is”之前。希望这会有所帮助！

【解决方案5】：

添加这一行：

   System.out.println("The time between " + departure + " and " + arrival + " is");

整个代码：

import java.util.Scanner;
public class Problem2 {
public static void main( String [] args) {

Scanner sc = new Scanner(System.in);

int seconds1;
int seconds2;
  int minutes;
  int hours;

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;

     System.out.println("The time between " + departure + " and " + arrival + " is"); // I am trying to get this to say "The time between + departure + and + arrival + is"
System.out.println(hours + " : " + minutes + " : " + seconds2);  


} }
