JAVA将2D数组的各个维度作为1D数组传递

Question

I'm trying to check if each row of an array, and then each column contains duplicate values (latin rectangle check). I made a method that checks a 1D array, but I can't figure out how to pass a part of a 2D array into it. Here's my 1D array checking method:

public static boolean hasDuplicates(int [] inArray)
   {
      for(int i = 0; i < inArray.length; i++)
         for(int j = i + 1; j < inArray.length; j++)
            if(inArray[i] == inArray[j])
               return true;
      return false; 
   }

Here's my mess of a method that calls my previous method:

   public static boolean arrayChecker(int[][] inArray)
   {
      int [] splitRows = new int[inArray.length];
      int [] splitCols = new int[inArray[0].length];

      for(int row = 0; row < inArray.length; row++)   
      {
         for(int col = 0; col < inArray[0].length; col++)
            splitRows[col] = inArray[row][col];

         if(hasDuplicates(splitRows))
               return true;
      }

      for(int col = 0; col < inArray[0].length; col++)  
      {
         for(int row = 0; row < inArray.length; row++)
            splitCols[row] = inArray[row][col];

         if(hasDuplicates(splitCols))
               return true;
      }


      return false;
   }

I know the problem with it right now is that my splitRows and splitCols arrays don't reset values after each loop, so when it runs again it will check new values vs the old ones. I can't seem to find a way around it. I tried setting the arrays = null before the loop, but that clears out the size and screws it up even more.

Any help is appreciated.

EDIT: Here's my call in my main method:

      if (arrayChecker(originalArray))
         System.out.println("Invalid");
      else
         System.out.println("Valid");

Answer 1

hasDuplicates(inArray[row])

将传递1d数组给hasDuplicates
