Before we move on, let’s create a map to work with: Notably, we’ve extended our example by adding an inner nested map. 3. Using Core Java As we know, Java can print maps using a built-intoString()method: The output is preformatted in a simple way, displaying key-value pairs sepa...
A map is a special type of collection that stores data in key-value pairs. These are also known as hashtables. The keys that are used to extract the value should be unique. You can create a mutable as well as an immutable map in Scala. The immutable version is inbuilt but mutable ...
