The Keyword Default

To specify the code to execute if there is no case match, you can use default keyword in switch statement. For example, the coffee machine has a list of types of coffee by its number (from 1 to 3). If you want to choose one, just type its number. But there is a huge amount of numbers that users can type by mistake. Here we can use the default keyword:

The default statement executes the code when the non of statements are true.

The default statement must be at the end of the switch.
