Question

这是myProgrammingLab任务，我不确定我在哪里出错。输出似乎混淆了变量，我不知道为什么。我已经包含了预期的输出和我的代码输出。

import java.util.Scanner;

public class WordGame
{
    public static void main(String[] args)
    {
        String name;
        int age;
        String city;
        String college;
        String profession;
        String animal;
        String pet;

        Scanner keyboard = new Scanner(System.in);

        System.out.print("Enter your name: ");
        name = keyboard.nextLine();     

        System.out.print("Enter your age: ");
        age = keyboard.nextDouble();

        System.out.print("Enter the name of a city: ");
        city = keyboard.nextLine();

        System.out.print("Enter the name of a college: ");      
        college = keyboard.nextLine();

        System.out.print("Enter profession: ");
        profession = keyboard.nextLine();

        System.out.print("Enter a type of animal: ");
        animal = keyboard.nextLine();

        System.out.print("Enter a pet name: ");
        pet = keyboard.nextLine();

        System.out.println("There once was a person named " + name + " who lived in " + city + "." + "At the age of\n" + age + ", " + name + " went to college at " + college + ". " + name + " graduated and went to\nwork as a " + profession + ". Then, " + name + " adopted a(n)" + animal + " named " + pet + ". \nThey both lived happily ever after!");

    }
}

Answer 1

您的代码正在跳过阅读城市字符串。

适合年龄使用

age= Integer.parseInt(keyboard.nextLine());

Java程序混合了字符串变量
