java - 类项目自动评分器说 "standard output is not what was expected"

Question

我是 java 的新手，正在为我的类(class)做一个项目，但我总是遇到错误。

Project

Write an application that reads values representing a time duration in hours, minutes, and seconds and then prints the equivalent total number of seconds. (For example, 1 hour, 28 minutes, and 42 seconds is equivalent to 5322 seconds.)

SPECIFICATION OF PROMPTS, LABELS AND OUTPUT: Your code should use these prompts: "hours: ", "minutes: ", "seconds: ". The prompts should not force the user to type the required input on the next line. After all the inputs, the output should consist of a single line consisting of an integer (the total number of seconds) followed by a space followed by a label for the units: seconds. For example:

hours: 2
minutes: 10
seconds: 7
7807 seconds 

SPECIFICATION OF NAMES: Your application class should be called Seconds

这些是 MyProgrammingLab 不断给我的错误:

我的代码:

import java.util.Scanner;

public class Seconds {
    
    public static void main (String[] args){
        
        Scanner stdin = new Scanner(System.in);
        int hours;
        System.out.print("hours: ");
        hours = stdin.nextInt();
        int minutes;
        System.out.print("minutes: ");
        minutes = stdin.nextInt();
        int seconds;
        System.out.print("seconds: ");
        seconds = stdin.nextInt();
        int hourSeconds = (hours * 60) * 60;
        int minuteSeconds = (minutes * 60);
        int secondsTotal = hourSeconds + minuteSeconds + seconds;
        System.out.println(secondsTotal + " seconds");
    
    }
                            }

Answer 1

作为提示，尝试:

...
System.out.print("hours: ");
int hours = stdin.nextInt();
...

检查print和println的区别

另请注意，您只需要打印提示，因此您只需打印:“小时:”。

分秒必争。
