Indexed Access Operator and Augmented Assignments

The indexed access operator

In programming, there are two popular conventions for getting or setting elements in collections.

• The first uses [] brackets

• The second uses the get and set methods

In Java, we use the first convention for arrays and the second one for other kinds of collections. In Kotlin, both conventions can be used interchangeably because the get and set methods are operators that can be used with [] brackets.
