转换一个二维数组索引一维指数 [英] Convert a 2D array index into a 1D index

问题描述

我有两个数组的国际象棋变体，我在Java编码......我至今一个控制台版本，重新presents板作为一维数组（大小为32），但我的工作作出图形用户界面，我希望它显示为4×8格，所以我有JPanels ...

I have two arrays for a chess variant I am coding in java...I have a console version so far which represents the board as a 1D array (size is 32) but I am working on making a GUI for it and I want it to appear as a 4x8 grid, so I have a 2-dimensional array of JPanels...

问题是，有没有可以在阵列转换任何式[I] [J]索引到数组[我]鉴于它是一个4×8阵列？

Question is, is there any formula that can convert the array[i][j] index into array[i] given the fact its a 4x8 array?

推荐答案

由于4列8行，那么：

i = row * 4 + col

编辑：我不好，没人抓我的这个错误很明显。但它实际上应该是行* 4 + COL 。

行* 8 + COL 将留在可能的不必要的索引差距。

row * 8 + col would leave unnecessary gaps in the possible indexes.
