2つの列に結果を出力するエラー

Question

タイトルと同じように2つの列に何かを印刷したいが、エラーが発生しているようだ。

int noOfHorseInList = 7; 
     String horseName[] = {"Blitz", "Sparky", "Sandy", "Rolo", "Beano", 

"Flash", "", "", ""}; 
     int horseAge[] = {2, 4, 1, 4, 4, 2, 0, 0, 0}; 
     int timeTakenInSeconds[] = {600, -1, 500, 430, 412, -1, 0, 0, 0}; 

    int option = 0; 

    System.out.println("Please choose from the following selection"); 
    System.out.println("1. Show horses that finished\n2. Show horse details\n3. Adding a Late Entrant"); 
    option = kb.nextInt(); 
    kb.hasNextLine(); 

    switch(option) 
    { 
    case 1: 
     //Finishers 
     String showHorseThatFinished = ""; 
     showHorseThatFinished = finishers(noOfHorseInList, horseName, timeTakenInSeconds); 

     String timeOfHorse = ""; 

     for(int i = 0; i < noOfHorseInList; i++) 
     { 
      if(timeTakenInSeconds[i] > -1) 
      { 
       timeOfHorse = timeOfHorse + "\n" + timeTakenInSeconds[i]; 
      } 
     } 


     System.out.println("Horses Name\tFinishing Time"); 
     System.out.println(showHorseThatFinished + "\t" + timeOfHorse); 



     break; 

    case 2: 
     //Horse details 





     break; 

    case 3: 
     //Adding Late Entrant 



     break; 

    } 

} 

public static String finishers(int noOfHorseInList,String horseName[],int timeTakenInSeconds[]) 
{ 
    String showHorseThatFinished = ""; 

    for(int i = 0; i < noOfHorseInList; i++) 
    { 
     if(timeTakenInSeconds[i] > -1) 
     { 
      showHorseThatFinished = showHorseThatFinished + "\n" + horseName[i]; 
     } 
    } 


    return showHorseThatFinished; 
}

は私が隣同士

Answer 1

...

はこれを見てとるもう

String timeOfHorse = ""; 

    for(int i = 0; i < noOfHorseInList; i++) 
    { 
     if(timeTakenInSeconds[i] > -1) 
     { 
      timeOfHorse = timeOfHorse + "\n" + timeTakenInSeconds[i]; 
     } 
    } 

コードのこの部分のための必要はありません

public static String finishers(int noOfHorseInList,String horseName[],int timeTakenInSeconds[]) { 
StringBuffer showHorseThatFinished = new StringBuffer(); 

for(int i = 0; i < noOfHorseInList; i++) { 
     // You need all horses to be written. Mark somehow that their time is erroneous 
     String time = "ERROR";  

     if (timeTakenInSeconds[i] > -1) { 
       time = "" + timeTakenInSeconds[i]; 
     } 

     showHorseThatFinished.append(horseName[i]); 
     showHorseThatFinished.append("\t"); 
     showHorseThatFinished.append(time); 
     showHorseThatFinished.append("\n"); 
    } 
} 

    return showHorseThatFinished.toString(); 
} 

方法：
フィニッシャー（int noOfHo rseInList、文字列horseName []、int型timeTakenInSeconds []）

はこのようにそれを変更：

public static String finishers(int noOfHorseInList, String horseName[], int timeTakenInSeconds[]) { 
     String showHorseThatFinished = ""; 

     for (int i = 0; i < noOfHorseInList; i++) { 
      if (timeTakenInSeconds[i] > -1) { 
       showHorseThatFinished = showHorseThatFinished + "\n" + horseName[i] + "\t\t\t" + timeTakenInSeconds[i]; 
      } 
     } 
     return showHorseThatFinished; 

    } 

と、あなたのテーブルには、で

for(int i = 0; i < noOfHorseInList; i++) 
     { 

の必要なしに行われますケース1：

Answer 2

に2列に値をしたい、私の出力でどのようにループのために以下の行を変更することについて -

timeOfHorse = timeOfHorse + "\t" + timeTakenInSeconds[i]; 

Answer 3

同じ機能で馬の名前と時間を追加します。

追加のためにStringBufferを使用します。より効率的です。ちょうどあなたが実際にはあまり計算している

System.out.println(showHorseThatFinished);
