If I have a 2D array arr[rows][columns], how could I use arr.length to find size for rows and columns individually?

A:
arr.length
will be the number of rows
arr[x].length
will be the number of columns in row x.

A:
You can find the number of rows as:
arr.length
In Java all the rows need not have same number of elements. You can find the number of elements in the row i as:
arr[i].length

Rows - arr.length
Columns -arr[rowNumber].length //Each row can have different number of elements
