Question

What is the advantage of Double Dimensional Array over single Dimensional Array?​

Answer 1

ANSWER

ADVATAGE OF 2D OVER 1D ARRAY

• if we require to store a table or matix ( data like in a spreadsheet) which has more then 1 row and more then 1 column then by 1D we need decalre it more then 1 time instead if we use 2D then declaration of array only one at a time required.
• modelling,relationship, network with a graph, linked list, stack require 2D array
• also we can convert 2D array as 1D array.
• we can store a image in 2D array ( images are made up of pictures element or pixel and each pixel is one element of the 2Darray )
• java stores a 2D array as array of arrays.

so we can say that not only 2D array is used as a 1D array but also it work in other functions also.

hope it helps you
