比較2個二維數組JAVA

Question

好的，下面是程序應該如何工作： 通過運行該程序，它會要求用戶輸入將玩樂途的玩家人數。例如，3.因此將創建3行數組，並將6列作爲默認列。現在在樂透數組中生成隨機數字後。然後它會生成一個獲勝的樂透。

問題是在這裏： 我已經完成了生成球員的樂透和獲獎樂透的部分。不過，我無法將獲勝樂透與玩家樂透相比。例如：

播放機0：1 15 30 41 56 12

播放機1：31 65 78 43 29 8

玩家2：41 28 1 6 38 14

獲獎樂透：15 30 56 12 41 1

即使排序不準確，獲勝者應該是玩家0。 但問題是我不能比較二維數組。

下面的代碼：

 

import javax.swing.*; 
import java.util.*; 


public class test{ 
    public static void main(String asd[]){ 

      int players = Integer.parseInt(JOptionPane.showInputDialog("Any NUMBER of PLAYERS\n[0] to exit")); 
      while(players != 0) 
      { 
       int typeOfLotto = Integer.parseInt(JOptionPane.showInputDialog("Type:\n[42] - SixFortyTwo\n[45] - SixFortyFive\n" + 
                   "[49] - SixFortyNine\n[55] - SixFiftyFive")); 
       String output="", playersLotto="", winning=""; 
       int taya = 6; 
       int index; 
       int[][] Lotto = new int[players][taya]; 
       int[][] winningLotto = new int[1][taya]; 
       for(index = 0; index<players; index++) 
       { 
        for(int column = 0; column<6; column++) 
        { 
         Lotto[index][column] = numberGen(typeOfLotto,Lotto,index); 
         output += Lotto[index][column] + " "; 
        } 
        playersLotto += "Player " + index + ": " + output +"\n"; 
        output=""; 
       } 



       //winning lotto 
       for(int column = 0; column<6; column++) 
       { 
        winningLotto[0][column] = winningNumberGen(typeOfLotto,winningLotto); 
        winning += winningLotto[0][column] + " "; 
        if(column==5) 
         winning = "Winning lotto: " + winning; 
       } 


       String win = checking(Lotto,winningLotto,players); 
       JOptionPane.showMessageDialog(null, playersLotto + "\n" + winning + "\n" + win); 
       players = Integer.parseInt(JOptionPane.showInputDialog("Any NUMBER of PLAYERS\n[0] to exit")); 
      } 










    } 

    public static int numberGen(int typeOfLotto,int Lotto[][],int index) 
    { 

     int random=0, loop=0; 
     if(typeOfLotto == 42) 
     { 
      random = (int)(1+Math.random()*42); 
       for(loop=0; loop<6; loop++) 
       { 
        if(Lotto[index][loop] == random) 
         return numberGen(typeOfLotto,Lotto,index); 
       } 
     } 

     return random; 
    } 
    //winning 
    public static int winningNumberGen(int typeOfLotto,int winningLotto[][]) 
    { 

     int random=0, loop=0; 
     if(typeOfLotto == 42) 
     { 
      random = (int)(1+Math.random()*42); 
       for(loop=0; loop<6; loop++) 
       { 
        if(winningLotto[0][loop] == random) 
         return winningNumberGen(typeOfLotto,winningLotto); 
       } 
     } 

     return random; 
    } 


    public static String checking(int Lotto[][], int winningLotto[][], int players) 
    { 
     int win[] = new int[6]; 
     int panalo=0; 
     String winner="", output=""; 
     for(int index=0; index<players;index++) 
     { 
      for(int loop=0;loop<6;loop++) 
      { 

       if(winningLotto[0][0] == Lotto[index][loop]) 
        win[loop] = Lotto[index][loop]; 
       if(winningLotto[0][1] == Lotto[index][loop]) 
        win[loop] = Lotto[index][loop]; 
       if(winningLotto[0][2] == Lotto[index][loop]) 
        win[loop] = Lotto[index][loop]; 
       if(winningLotto[0][3] == Lotto[index][loop]) 
        win[loop] = Lotto[index][loop]; 
       if(winningLotto[0][4] == Lotto[index][loop]) 
        win[loop] = Lotto[index][loop]; 
       if(winningLotto[0][5] == Lotto[index][loop]) 
        win[loop] = Lotto[index][loop]; 
      } 

     } 

     if(win[0] > 0) 
      panalo++; 
     if(win[1] > 0) 
      panalo++; 
     if(win[2] > 0) 
      panalo++; 
     if(win[3] > 0) 
      panalo++; 
     if(win[4] > 0) 
      panalo++; 
     if(win[5] > 0) 
      panalo++; 


     if(panalo > 3) 
     { 
      for(int loop=0;loop<6;loop++) 
      { 
       winner += win[loop] + " "; 
      } 
      output = "Winner: " + winner; 
     } 
     else if(panalo < 3) 
      output = "no winner"; 

     return output; 
    } 

} 

我沒有，因爲我還在一個第一年的大學有很多關於Java的知識。那麼我可以問簡單的代碼嗎？我想在for循環中進行比較。我只知道基本。我希望最簡單的代碼可以做到。

修訂新增1層的方法來檢查它爲1的球員，但犯規超過1

UPDATE回答它自己。

Answer 1

首先排序贏得樂透

Arrays.sort(winninglotto); 

然後爲您的每個球員得到的數字數組排序，然後看看它們是否等於贏得樂透

Arrays.sort(playernumbers); 
return Arrays.equals(playernumbers, winninglotto); 

這樣的：

public static String checking(int Lotto[][], int winningLotto[][], int players) 
{ 
Arrays.sort(winningLotto[0]); 
for(int i =0; i < players;i++){ 
    Arrays.sort(Lotto[i]); 
    if(Arrays.equals(Lotto[i], winningLotto[0])){ 
     //we have a winnder 
    } 
} 
}
