java - 在数组中搜索值但仅打印第一个实例[更新]

Question

我正在制作一个赛马程序，该程序将打印第一名、第二名和第三名的马匹。我必须将 10 匹马设置为一个数组，然后将 1-3 中的随机数添加到它们的位置。获胜者是第一匹达到 15 或以上的马。

我的问题是我的程序无法正确打印第二名和第三名的马匹。

[更新]我删除了许多条件并添加了字符串变量来存储信息。它运行更流畅，但现在我不知道为什么程序不断打印重复项之类的。

这是代码，我更新了打印获胜者的 for 循环:

import java.util.*;
public class HorseRace{
  public static void main(String[ ] arg){
   Scanner reader = new Scanner(System.in);
   int range = 3;
   int win = 15;
   final int SIZE = 5;
   Random ran = new Random( );
   boolean winner = false;
   boolean second = false;
   int[ ] arrRan = new int[SIZE];

    System.out.print("Off to the races! Press enter to make the horses run.");

    String readString = reader.nextLine();
    while(winner!=true){//loop forever until winner
    //begin program
      System.out.print(readString);
      if(readString.equals("")){//when enter is pressed

         for(int i = 0; i<arrRan.length; i++){//loop that adds position when enter is pressed
            arrRan[i] = arrRan[i] + (ran.nextInt(3) + 1); //add to the array in random numbers
            System.out.println("Horse " + (i+1) + ": " + arrRan[i]);//print the contents of the array
         }       
      }//end if
      if(reader.hasNextLine()){
         readString = reader.nextLine();
         System.out.println("Please press enter.");
      }
  for(int i = 0; i<arrRan.length; i++){
     if(arrRan[i]>=15){//if a winner is found
        first = first + "Horse " + (i+1)+" ";
        winner = true;

     }

     //if winner is found then look for a 2nd place
     //if there is no position 14 then search for 13, if no 13 then 12. The lowest 2nd place will be in position 12. 
     if(arrRan[i]==14){
        second = second + "Horse " + (i+1)+" ";
        secondPl = true;

     }
     if(arrRan[i]!=14&&arrRan[i]==13){
        second = second + "Horse " + (i+1)+" ";
        secondPl = true;  
     }
     if(arrRan[i]!=13&&arrRan[i]==12){
        second = second + "Horse " + (i+1)+" ";
        secondPl = true;  
     }
     if(arrRan[i]==13){
        third = third + "Horse " + (i+1)+" "; 
     }         
  }
  if(winner==true){
  System.out.println(first);
  System.out.println(second);
  System.out.println(third);
  }      

    }//end while
   }//close main
}//close class

您可以使用 break 语句退出 for 循环。
