所以我正在为我的 java 类创建 Kevin Bacon 游戏。
这些是我必须使用的名称文件
演员：
Leonardo Dicaprio
Susan Sarandon
Tom Hanks
Robert De Niro
Barack Obama
Helen Keller
Katharine Cornell
Helen Hayes
John Laughlin
Mark Zuckerberg
Joe Lipari
Welker White关系：
Susan Sarandon | Tom Hanks : Cloud Atlas
Tom Hanks | Kevin Bacon : Apollo 13
Leonardo Dicaprio | Kevin Bacon : This Boy's Life
Robert De Niro | Kevin Bacon : This Boy's Life
Barack Obama | Tom Hanks : the Road We've Traveled
Helen Keller | Katharine Cornell : Helen Keller in Her Story
Katharine Cornell | Helen Hayes : Stage Door Canteen
Helen Hayes | John Laughlin : Murder with Mirrors
John Laughlin | Kevin Bacon : Footloose
Mark Zuckerberg | Joe Lipari : Terms and Conditions May Apply
Joe Lipari | Welker White : Eat Pray Love
Welker White | Kevin Bacon : Lemon Sky这是我现在拥有的程序：
package Game;
import java.io.*;
import java.util.HashMap;
import java.util.Scanner;
import java.util.regex.Pattern;
/**
* @author
*
*/
public class BaconNumber
{
/**
* @param args
*/
private HashMap<String,String> relationships;
private HashMap<String,String> actors;
public static void main(String[] args)
throws FileNotFoundException
{
Scanner input = new Scanner(new File("relationships"));
HashMap<String, String> relationships = new HashMap<String, String>();
while (input.hasNextLine()) {
String[] columns = input.nextLine().split(Pattern.quote(" | "));
relationships.put(columns[0], columns[1]);
}
System.out.println(relationships);
}
public BaconNumber()
{
relationships = new HashMap<String,String>();
actors = new HashMap<String,String>();
}
public void printActors() throws FileNotFoundException
{
Scanner input = new Scanner(new File("actors"));
while (input.hasNextLine())
{
System.out.println(input.nextLine());
}
}
public int getBaconNumber( String actor , int number)
{
if( actor == "Kevin Bacon")
{
return number;
}
else
{
relationships.get(actor);
System.out.println(actor + " starred in " + relationships.value + "with" + relationships.value );
System.out.println( " The Bacon Number for " + actor + " is " + number );
return number; // fix this
}
relationships.containsKey("Kevin Bacon")
// {
// number++;
// System.out.println(" The bacon number for" + actor + " is " + number );
// }
// else
// {
//
// }
}
}我的 getBaconNumber() 需要一些帮助，我需要程序来查找演员并计算最终到达凯文培根时的培根编号。
下面是教授对这个程序的要求： 1. 在你的 hashmap 中查找 actor 关系 2. 将当前关系打印到控制台 3. 使用关系中的第二个 actor 递归调用该方法（确保增加你的 bacon 编号）。
这种方法让我感到困惑，我无法完成它。
我需要它来打印这样的东西：
Helen Keller
Helen Keller starred in "Helen Keller in her story" with Katherine Cornell.
Katherine Cornell starred in " Stage Door Canteen " with Helen Hayes.
Helen Hays starred in "Murder with mirrors" with John Laughlin.
John Laughlin starred in " FootLoose" with Kevin Bacon.
The bacon number for Helen Keller is 4如果有人可以提供帮助，请我真的需要帮助吗
