java交錯數組_Java和C#數組都可以交錯的

Arrays Can Be Jagged

In languages like C and C++, each subarray of a multidimensional array must have the same dimensions.

在C和C++語言中，多元數組的子數組必須要有相同的維數。

In Java and C# arrays do not have to be uniform because jagged arrays can be created as one-dimensional arrays of arrays. In a jagged array the contents of the array are arrays which may hold instances of a type or references to other arrays.

在Java和C#中，數組不一定要一緻，因為交錯數組能被生成作為一維數組的數組。

在交錯數組中，數組的内容是數組，它們裡面容納一個類型的很多執行個體或引用其他數組。

例子：

int [][]myArray = new int[2][];

myArray[0] = new int[3];

myArray[1] = new int[9];
