如何将2D数组的数量添加到数组

Question

For now, i am having 8 number of 2D array eg arrayInput1 until arrayInput8 . So now the data from the 2D array is 1 and 0 and let set the size of the array is 25.

 for(int a=0; a<5; a++){
     for(int b=0; b<4; b++){
         arrayInput1[a][b] //----> The result here is 0
         arrayInput2[a][b] //----> The result here is 1
         arrayInput3[a][b] //----> The result here is 0
         arrayInput4[a][b] //----> The result here is 1
         arrayInput5[a][b] //----> The result here is 0
         arrayInput6[a][b] //----> The result here is 1
         arrayInput7[a][b] //----> The result here is 0
         arrayInput8[a][b] //----> The result here is 1
     }
 }//end of nested for loops

So the result from those arraiInput i will get 01010101 . Then I want to store them in an array . So the first index of array will print 01010101

So the question is How to do that ?

Answer 1

You've got pixel data in eight bit-planes. You want to merge these into a single plane of eight-bit integer pixels. Here's an example of how to do it:

int newPixels[][] = 
    new int[arrayInput1.length][arrayInput1[0].length];

for(int a=0; a<arrayInput.length; a++){
    for(int b=0; b<arrayInput1[0].length; b++){
         newPixels[a][b] =
         arrayInput1[a][b] * 128 +
         arrayInput2[a][b] * 64 +
         arrayInput3[a][b] * 32 +
         arrayInput4[a][b] * 16 +
         arrayInput5[a][b] * 8 +
         arrayInput6[a][b] * 4 +
         arrayInput7[a][b] * 2 +
         arrayInput8[a][b];
    }
}

Here I've assumed that arrayInput1 holds the bits that should become the most significant bits in the merged pixels, arrayInput2 holds the next highest significant bits, and so on down to arrayInput8 which holds the least significant bits.

Answer 2

You should initialize it directly : int[] data = {0,1,0,1,0,1,0,1}; and int[][] data2d = {data, data, data, data, data, data, data, data}

Answer 3

Use a StringBuilder (or similar) to build a string from the int values and add it to a String array. I was unsure about the array sizes so I used two constants instead.

String[][] result = new String[ROW_SIZE][COLUMN_SIZE];
for(int a = 0; a < ROW_SIZE; a++){
   for(int b = 0; b < COLUMN_SIZE; b++){
      StringBuilder builder = new StringBuilder(8);        
      builder.append(arrayInput1[a][b]);
      builder.append(arrayInput1[a][b]); 
      builder.append(arrayInput1[a][b]);
      builder.append(arrayInput2[a][b]);
      builder.append(arrayInput3[a][b]);
      builder.append(arrayInput4[a][b]);
      builder.append(arrayInput5[a][b]);
      builder.append(arrayInput6[a][b]);
      builder.append(arrayInput7[a][b]);
      builder.append(arrayInput8[a][b]);
      result[a][b] = builder.toString();
   }
}
