In Kotlin, you can concatenate two arrays using the + operator, as well as the plus() function. Here's an example using both:
val array1 = arrayOf("apple", "banana", "orange")
val array2 = arrayOf("grape", "mango", "pineapple")
// using the + operator
val concatenatedArray1 = array1 + array2
println(concatenatedArray1.contentToString())
// using the plus() function
val concatenatedArray2 = array1.plus(array2)
println(concatenatedArray2.contentToString())
Output:
[apple, banana, orange, grape, mango, pineapple]
[apple, banana, orange, grape, mango, pineapple]
In the above example, we first defined two arrays array1 and array2 containing some fruits. We then concatenated them using the + operator and the plus() function to create concatenatedArray1 and concatenatedArray2, respectively. Finally, we printed the contents of both concatenated arrays using the contentToString() function.
