Kotlin basics : Using arrays in the code

- We use arrays when we have a fixed list of items.
- We are not adding or removing the elements from the array in regular intervals of time.
- Accessing the elements is very quick here.
private fun initiate() {
// Declaring the array
var listOfCities = arrayOf("Mumbai","Bangalore","Delhi","Chennai")
// This will print the address of the array
println(listOfCities)
// This will print the size of the array
println(listOfCities.size)
// This will access the element from a index
println(listOfCities[1])
// Check if the array has a particular element
println(listOfCities.contains("Bangalore"))
// Another way to check if the element is present in the arrays
println("Bangalore" in listOfCities)
// Getting the first element in the array
println(listOfCities.first())
// Getting the last element in the array
println(listOfCities.last())
// This will throw the error Index out of bound
println(listOfCities[-1])
}
