How Can This Java For Loop Be More Readable?
问题
我正在尝试找到一种方法来减少这种重复，我尝试过使用更多的for循环，但由于每个数组的遍历方式都不同，我感到困难。
for (int i = 0; i < size; i++) {warray[i][0] = narray[i][0] * pcarray[i][0];warray[i][1] = narray[i][0] * pcarray[i][1];warray[i][2] = narray[i][1] * pcarray[i][0];warray[i][3] = narray[i][1] * pcarray[i][1];warray[i][4] = narray[i][2] * pcarray[i][0];warray[i][5] = narray[i][2] * pcarray[i][1];warray[i][6] = narray[i][3] * pcarray[i][0];warray[i][7] = narray[i][3] * pcarray[i][1];warray[i][8] = narray[i][4] * pcarray[i][0];warray[i][9] = narray[i][4] * pcarray[i][1];warray[i][10] = narray[i][5] * pcarray[i][0];warray[i][11] = narray[i][5] * pcarray[i][1];warray[i][12] = narray[i][6] * pcarray[i][0];warray[i][13] = narray[i][6] * pcarray[i][1];warray[i][14] = narray[i][7] * pcarray[i][0];warray[i][15] = narray[i][7] * pcarray[i][1];warray[i][16] = narray[i][8] * pcarray[i][0];warray[i][17] = narray[i][8] * pcarray[i][1];warray[i][18] = narray[i][9] * pcarray[i][0];warray[i][19] = narray[i][9] * pcarray[i][1];}
英文:
I am trying to figure out a way to achieve this without so much repetition, I have tried using more for loops, but since each array has to been looped through so differently I am struggling.
for (int i = 0; i < size; i++) {warray[i][0] = narray[i][0] * pcarray[i][0];warray[i][1] = narray[i][0] * pcarray[i][1];warray[i][2] = narray[i][1] * pcarray[i][0];warray[i][3] = narray[i][1] * pcarray[i][1];warray[i][4] = narray[i][2] * pcarray[i][0];warray[i][5] = narray[i][2] * pcarray[i][1];warray[i][6] = narray[i][3] * pcarray[i][0];warray[i][7] = narray[i][3] * pcarray[i][1];warray[i][8] = narray[i][4] * pcarray[i][0];warray[i][9] = narray[i][4] * pcarray[i][1];warray[i][10] = narray[i][5] * pcarray[i][0];warray[i][11] = narray[i][5] * pcarray[i][1];warray[i][12] = narray[i][6] * pcarray[i][0];warray[i][13] = narray[i][6] * pcarray[i][1];warray[i][14] = narray[i][7] * pcarray[i][0];warray[i][15] = narray[i][7] * pcarray[i][1];warray[i][16] = narray[i][8] * pcarray[i][0];warray[i][17] = narray[i][8] * pcarray[i][1];warray[i][18] = narray[i][9] * pcarray[i][0];warray[i][19] = narray[i][9] * pcarray[i][1];}

虽然不同，但它们确实遵循一种模式：
for (int i = 0; i < size; i++)for (int j = 0; j < 20; j++)warray[i][j] = narray[i][j/2] * pcarray[i][j%2];
英文:
While different, they do follow a pattern:
for (int i = 0; i < size; i++)for (int j = 0; j < 20; j++ )warray [i][j] = narray [i][j/2] * pcarray[i][j%2];
