得到错误，当3D阵列声明 [英] getting error while 3D array declare

问题描述

可能是我使用的三维数组的第一次。我只是尝试按照一维和二维语法来声明3D，但编译器说类型不匹配。谁能告诉我这背后的原因是什么？

May be I am using 3D arrays first time. I just try to follow the 1D and 2D syntax to declare 3D, but compiler says Type mismatch. Can anyone tell me the reason behind this?

Integer[] _1D = new Integer[]{2,4,6,5,6};
Integer[][] _2D = new Integer[][]{{2,3},{4,6},{5,6}};
Integer[][][] _3D = new Integer[][][]{{1,2,3},{4,5,6},{7,8,9},{2,4,5}};

谢谢，

推荐答案

你只是创建的 2-D阵列的了，但与 4行3列的。这是创建一个三维数组的正确途径。

You're just creating a 2-d array again, but with 4 rows and 3 columns. This is the right way to create a 3-d array.

Integer[][][] _3D = new Integer[][][]{{{1,2,3},{4,5,6},{7,8,9},{2,4,5}},{{1,2,3},{4,5,6},{7,8,9},{2,4,5}}}; // it should be like this.
