计算演员并存储和显示他们的姓名和角色

Question

我是 Java 新手，我正在尝试从不同的网站和视频中学习，但我已经被一个问题困住了几天，我想知道任何人都可以帮忙。我想做的是询问用户一部电影中有多少关键演员。然后我想问演员的名字和他们在电影中扮演的角色，在最终显示演员的名字和他的角色之前，应该询问每个演员，无论用户指定的电影中有多少人？

import java.util.Scanner;

public class rough {

    public static void main(String[] args) {
        // TODO Auto-generated method stub


        int actorCount;

        Scanner input = new Scanner(System.in);
        Scanner kb = new Scanner(System.in);


        System.out.println("How many actors are in the film? ");
        actorCount = kb.nextInt();


        for (int k = 1; k <= actorCount ; k++)
        {
            float actor, character; 
            System.out.println("What is the actors name? ");
            actor = kb.nextFloat();

            System.out.println("What is " + actor + "'s character?");
            character = kb.nextFloat();


            System.out.print(actor + " - " + character);

        }

        kb.close();
        input.close();
    }

}

Answer 1

这就是我会做的：

import javax.swing.*;

public class rough {

    public static void main(String[] args) {
    // TODO Auto-generated method stub


    int actorCount;
    String output = "";

    actorCount = Integer.parseInt(JOptionPane.showInputDialog(null,"How many actors are in the film? "));

    for (int k = 1; k <= actorCount ; k++)
    {
        String actor, character; 
        actor = JOptionPane.showInputDialog(null, "What is the actors name?");
        character = JOptionPane.showInputDialog(null, "What is " +actor + "s character?");


        output +=  actor + " - " + character + "\n";
    }

    JOptionPane.showMessageDialog(null, output);
    }
}

请记住，如果您希望同时打印所有角色/演员，您必须将打印放在 for 循环之外并将角色/演员存储到某个输出字符串。此外，我看不出你为什么对角色/演员使用浮点变量，字符串是最合乎逻辑的。

所以你应该这样做：

public static void main(String[] args) {
     int actorCount;

    Scanner input = new Scanner(System.in);
    Scanner kb = new Scanner(System.in);


    System.out.println("How many actors are in the film? ");
    actorCount = kb.nextInt();

    String[][] actorValues = new String[actorCount][2];

    for (int k = 0; k < actorCount ; k++)
    {
        String actor, character; 
        System.out.println("What is the actors name? ");
        actor = kb.next();

        System.out.println("What is " + actor + "'s character?");
        character = kb.next();


        System.out.print(actor + " - " + character +"\n");
        actorValues[k][0] = actor;
        actorValues[k][1] = character;

    }


    //Printout the Characters in the List
    System.out.println("All Actors:");
    for (int i = 0; i < actorValues.length; i++) {
        String[] strings = actorValues[i];
        System.out.println("Actorssname: "+strings[0]+" Character:"+strings[1]);

    }

    kb.close();
    input.close();
}
