具有不同长度的二维数组(Java) [英] Two dimensional array with different lengths (Java)

问题描述

是否有机会在第二维中创建具有不同长度的二维数组?例如这样的

Is there an opportunity to create two dimensional Arrays with different lengths in the second dimension? For example like this:

[true] [true] [true]

[true] [true] [true]

[true]

[true] [true] [true] [true] [true]

[true] [true] [true] [true] [true]

最好不要创建其他类(例如存储桶)，也不知道数组的实际长度.

Preferably without creating another class (like buckets) and without knowing the actual length of the array.

推荐答案

是的，二维数组中的数组没有相同的大小.例如:

Yes, arrays in a 2D array don't have the have same size. E.g.:

boolean[][] twoDimensionalArray = new boolean[3][];
twoDimensionalArray[0] = new boolean[]{true, true, true};
twoDimensionalArray[1] = new boolean[]{true};
twoDimensionalArray[2] = new boolean[]{true, true, true, true, true};
