无法摆脱输入中的空格

Question

我正在尝试编写州和首都测验的代码，我几乎完成了它，但是当我尝试输入任何我必须输入 2 个单词的首都（即小石城或俄克拉荷马城）时，它有它作为 2 个独立的输入，在我的一生中，我无法将它算作一个。

到目前为止，这是我的代码：

public static void main(String[] args) {
    Scanner input = new Scanner (System.in);
    
    ArrayList<String> States = new ArrayList<>();
    ArrayList<Object> Capitals = new ArrayList<>(States);
    
    
    String capitals [][] = {
        {"Alabama", "Montgomery"},
        {"Alaska", "Juneau"},
        {"Arizona", "Phoenix"},
        {"Arkansas", "LittleRock"},
        {"California", "Sacramento"},
        {"Colorado", "Denver"},
        {"Connecticut", "Hartford"},
        {"Delaware", "Dover"},
        {"Florida", "Tallahasse"},
        {"Georgia", "Atlanta"},
        {"Hawaii", "Honolulu"},
        {"Idaho", "Boise"},
        {"Illinois", "Springfield"},
        {"Indiana", "Indianapolis"},
        {"Iowa", "DesMoines"},
        {"Kansas", "Topeka"},
        {"Kentucky", "Frankfort"},
        {"Louisiana", "BatonRouge"},
        {"Maine", "Augusta"},
        {"Maryland", "Annapolis"},
        {"Massachusettes", "Boston"},
        {"Michigan", "Lansing"},
        {"Minnesota", "Saint Paul"},
        {"Mississippi", "Jackson"},
        {"Missouri", "JeffersonCity"},
        {"Montana", "Helena"},
        {"Nebraska", "Lincoln"},
        {"Nevada", "CarsonCity"},
        {"New Hampshire", "Concord"},
        {"New Jersey", "Trenton"},
        {"New York", "Albany"},
        {"New Mexico", "SantaFe"},
        {"North Carolina", "Raleigh"},
        {"North Dakota", "Bismark"},
        {"Ohio", "Columbus"},
        {"Oklahoma", "OklahomaCity"},
        {"Oregon", "Salem"},
        {"Pennslyvania", "Harrisburg"},
        {"Rhode Island", "Providence"},
        {"South Carolina", "Columbia"},
        {"South Dakota", "Pierre"},
        {"Tennessee", "Nashville"},
        {"Texas", "Austin"},
        {"Utah", "Salt Lake City"},
        {"Vermont", "Montpelier"},
        {"Virginia", "Richmond"},
        {"Washington", "Olympia"},
        {"West Virginia", "Charleston"},
        {"Wisconsin", "Madison"},
        {"Wyoming", "Cheyenne"}
    };
    
    
    for(int i = 0; i<=49; i++){
        States.add(capitals[i][0]);
        Capitals.add(capitals[i][1]);
    }
    
    
    for(int i = 0; i<49; i++){
        String guess;
        int index = (int)((Math.random())*(49 - i));
        System.out.println("What is the capital of: " + States.get(index));
        States.remove(index);
        
        guess = input.next();
        
        if(Capitals.get(index).equals(guess)){
            System.out.println("Correct");
            Capitals.remove(index);
        }else{ System.out.println("Incorrect");
            Capitals.remove(index);
        }
    }
    
    
}

Answer 1

详细说明@Gus 在这里所说的内容 " 您可以更改定界符模式，也可以使用 nextLine()",

阅读单个标记可能是您的失败。 "I like pie" 读作 "I" "like" "pie" with line.next() 但一起读作 "I like pie" with line.next行()

编辑更多细节 引入示例行：

for(int i = 0; i<=49; i++)    // {"Utah", "Salt Lake City"},
{
    States.add(capitals[i][0]); // add Utah
    Capitals.add(capitals[i][1]); // add Salt
}

在这个索引中，capitals[44][]，大小设置为 4，因为每个单词都被读取。
