Проблемы с CharSequence

Question

Я только начал изучать, как код 2 недели назад, и у меня, похоже, возникли проблемы с идеей использования CharSequence.

Я пишу простую программу, основанную на телешоу «Игра престолов», которая позволяет мне печатать имена, их пристрастия и независимо от того, живы ли они или умерли, используя ArrayList.

Это мой символы Класс:

import java.util.ArrayList; 

public class Characters { 

/* Fields */ 
private String name; 
private String allegiance; 
private String status; 
private int seasonSeen; 


/* Constructor */ 
public Characters(String name, String allegiance, String status, int seasonSeen) { 
    this.name = name; 
    this.allegiance = allegiance; 
    this.status = status; 
    this.seasonSeen = seasonSeen; 
} 

/* Methods */ 

public String getName() { 
    return name; 
} 

public String getallegiance() { 
    return allegiance; 
} 

public String getStatus() { 
    return status; 
} 

public int getseasonSeen() { 
    return seasonSeen; 
} 

} 

Это мой тестовый класс

import java.util.ArrayList; 

public class TestGoTCharacters { 

public static void main(String[] args) { 


// create an arraylist called character 
ArrayList<Characters> character = new ArrayList<Characters>(); 

    // character paramaters(name, allegiance, status, season appearance) into the arraylist 
    character.add(new Characters("Jon Snow", "House Stark, The Nights Watch", "Alive", 1)); 
    character.add(new Characters("Neddard Stark", "House Stark", "Deceased", 1)); 
    character.add(new Characters("Arya Stark", "House Stark, Faceless Men", "Alive", 1)); 
    character.add(new Characters("Catelyn Stark", "House Stark", "Deceased", 1)); 
    character.add(new Characters("Sansa Stark", "House Stark", "Alive", 1)); 
    character.add(new Characters("Bran Stark", "House Stark", "Alive", 1)); 
    character.add(new Characters("Rickon Stark", "House Stark", "Deceased", 1)); 
    character.add(new Characters("Cersei Lannister","House Lannister, House Baratheon", "Alive", 1)); 
    character.add(new Characters("Jamie Lannister", "House Lannister, Kingsguard", "Alive", 1)); 
    character.add(new Characters("Tyrion Lannister", "House Lannister, House Targaryen", "Alive", 1)); 
    character.add(new Characters("Tywin Lannister", "House Lannister", "Deceased", 1)); 
    character.add(new Characters("Robert Baratheon", "House Baratheon, House Baratheon of Kings Landing", "Deceased", 1)); 
    character.add(new Characters("Stannis Baratheon", "House Baratheon, House Baratheon of Dragonstone", "Deceased", 2)); 
    character.add(new Characters("Renly Baratheon", "House Baratheon", "Deceased", 1)); 
    character.add(new Characters("Melissandre", "The lord of light", "Alive", 2)); 
    character.add(new Characters("Margaery Tyrell", "House Tyrell, House Baratheon, House Baratheon of Kings Landing", "Deceased", 2)); 
    character.add(new Characters("Sandor 'The Hound' Clegane", "House Baratheon of Kings Landing, Brotherhood without Banners", "Alive", 1)); 
    character.add(new Characters("Joffrey Baratheon", "House Baratheon of Kings Landing, House Lannister", "Deceased", 1)); 
    character.add(new Characters("Gregor 'The Mountain' Clegane", "House Lannister", "Alive", 1)); 
    character.add(new Characters("Khal Drogo", "Dothraki", "Deceased", 1)); 
    character.add(new Characters("Benjen Stark", "House Stark, The Nights Watch", "Alive", 1)); 
    character.add(new Characters("Ramsay Bolton", "House Bolton", "Deceased", 3)); 
    character.add(new Characters("Daenarys Targayen", "House Targaryen", "Alive", 1)); 
    character.add(new Characters("Viserys Targaryen", "House Targaryen", "Deceased", 1)); 
    character.add(new Characters("Rhaegar Targaryen", "House Targaryen", "Deceased", 7)); 
    character.add(new Characters("Petyr Baelish", "House Baelish", "Alive", 1)); 
    character.add(new Characters("Robb Stark", "House Stark", "Deceased", 1)); 
    character.add(new Characters("Theon Greyjoy", "House Targaryen, House Stark, House Greyjoy", "Alive", 1)); 
    character.add(new Characters("Yara Greyjoy", "House Greyjoy", "Alive", 2)); 



    /* method that reads out names in the array list */ 
    /* 
    int count = 1; 
    System.out.println("Some of the characters in Game of Thrones, are: "); 
    for (int i = 0; i < character.size(); i++) { 
     System.out.println(count + ". " + character.get(i).getName()); 
     count = count + 1; 
    } 
    */ 


    /* method that finds house allegiances */ 

    System.out.println("\n"); // create a line space 
    System.out.println("The following characters are loyal to House Stark: "); 
    CharSequence HouseStark = "House Stark"; // if Allegiance contains House Stark then, print the name 
    for (int i = 0; i < character.size(); i++) { 
     // if (characer.get(i_.getallegiance() == "House Stark") 
     if (character.get(i).getallegiance() == HouseStark)// compares if allegiance paramters is true (equals house stark) 
      System.out.println(character.get(i).getName()); 
    } 



    /* method that finds deceased */ 

    /* method that finds characters seen in season 1 */ 

    /* method that finds characters seen other than season 1 */ 

} 
} 

Это то, что он читает, но мне кажется, заметить символы, такие как «Джон Сноу» не в выход, хотя я упомянул в параметрах «House Stark, The Nights Watch»

The following characters are loyal to House Stark: 
Neddard Stark 
Catelyn Stark 
Sansa Stark 
Bran Stark 
Rickon Stark 
Robb Stark 

Answer 1

У вас есть комм. a в лозунге «Джон Сноу» (с более чем один значение, поэтому они не равны). allegiance является String, так что вы могли использовать String.contains как

if (character.get(i).getallegiance().contains(HouseStark))
