For this functionality we have Multidimensional Collections (or Nested Collections) in java. What is Multidimensional Collections in java? Multidimensional Collections (or Nested Collections) is a collection of group of objects where each group can have any number of objects dynamically.
Consequently, Need for Multidimensional Collections in java? Unlike Arrays we are not bound with the size of any row in Multidimensional collections. Therefore, if we want to use a Multidimensional architecture where we can create any number of objects dynamically in a row, then we should go for Multidimensional collections in Java. Just so, A multidimensional array is an array of arrays. Each element of a multidimensional array is an array itself. For example, Here, we have created a multidimensional array named a. It is a 2-dimensional array, that can hold a maximum of 12 elements, Remember, Java uses zero-based indexing, that is, indexing of arrays in Java starts with 0 and not 1. Subsequently, Multidimensional collections are also known as Nested collections. It is a group of objects wherein every group has any number of objects that can be created dynamically. They can be stored in any position as well. Next, A simple forEach or flatMap methods in Java 8, in combination with method references, can be used for flattening nested collections.
