I want to create a ragged 3d array as followes in java.
Terminology : A 2D array is said to consist of rows and columns. A 3D array is said to consist of slabs, where each slab consists of a 2D array.
The first slab has three rows, the second slab five rows, and the third slab seven rows (ie, if s denotes the slab, the number of rows in the sth slab is 3+2*s). Within the sth slab, the jth row should have s+j+1 columns
My approach was,
int[][][] mat3d = new int[3][][];
mat3d[0] = new int[3][];
mat3d[0] = new int[5][];
But this gives a compile error. Can anyone please help me to do this. I'm in a real hurry.
Error was not due to the code fragment in the question. Compilation failed as the code was not written inside a method. Writing the code with in a method fixes the problem.
public static void main(String args[]){
int[][][] mat3d = new int[3][][];
mat3d[0] = new int[3][];
mat3d[0] = new int[5][];
}
This compiles fine.
