如何使用文本文件中的键值创建HashMap？

Question

I have to create a hashmap with the names I have in this text file

relationships text file:

 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 

This is the program I have now:

 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(" "); relationships.put(columns[0], columns[1]); } System.out.println(relationships); } 

This is the output:

 {Leonardo=Dicaprio, Katharine=Cornell, Joe=Lipari, Tom=Hanks, Robert=De, Susan=Sarandon, John=Laughlin, Mark=Zuckerberg, Barack=Obama, Welker=White, Helen=Hayes} 

Does anyone know how to fix this please? Also how to seperate them so it actually looks like a list?

Answer 1

EDIT

I think you would just change your line:

String[] columns = input.nextLine().split(" ");

to:

String[] columns = input.nextLine().split(Pattern.quote(" | "));

Then column[0] would be the name on the left, and column[1] would be the name and movie title on the right.

Note that you'll need to import java.util.regex.Pattern; to do this
