Question

How to find the lengths of a multidimensional array with non equal indices?

For example, I have int[][] pathList = new int[6][4]

Answer 1

In java we can define array of arrays which we call multi dimensional arrays.By array of arrays we mean that a single elment of our array is again an array (in java can be of multiple length).To find length of multi array having all subarray of same size,we can use:

int[][]a=new int[3][3];//let a[][] be my array
a.length will work.   //a is an object of proxy class and length is its property.

However,if you have subarrays of different sizes then you have to iterate it.
