   "This creates a 2-dimensional array of integers with 10 rows and 20 columns. Once created, we can index individual elements by specifying row and column indices.\n\n1 for(int i=0; i<matrix.length; i++

2. How do Java lists provide dynamic data structures?

   "The Java SDK provides a rich assortment of dynamic data structures as alternatives to arrays including lists, sets and maps. The classes that support and implement these data structures are defined i

3. How do Java sets store unordered unique elements?

   "Another type of collection supported by the Collections library is a Set. A set differs from a list in that it is unordered. There is no concept of the first element or last element. Moreover, a Set

4. How does a Java map store and retrieve key-value pairs?

   "Finally, Java also supports a Map data structure which allows you to store key-value pairs. The keys and values can be any object type and are specified by two parameters when you create the map. A c
