二维数组在处理中的声明 [英] Declaration of 2 Dimensional Array in Processing

问题描述

可以在处理过程中分两步或一步地初始化和声明一维数组。

It is possible in processing to initialize and declare a one dimensional array in two steps, or in one.

int []a;

a= new int[100];

等效于：

int [] a=new int [100];

我想知道是否存在与上述类似的二维数组相同方法

I would like to know if there is a similar method as above to do the same for 2 dimensional array.

int [][] array= new int[100][200];

推荐答案

// this??

int[][] a;

a = new int [100][200];

println("a.\'x\' length: " + a.length);
println("a.\'y\' length: " + a[0].length);

//or maybe... this?

int[][] b;

b = new int [100][];


for(int i = 0; i < b.length; i++){
  b[i] = new int[200];
}

println("b.\'x\' length: " + b.length);
println("b.\'y\' length: " + b[0].length);

确定您也可以使用二维数组列表

Sure you know you can have a two dimensions arraylist also
