Write a Kotlin Program to Join Two Lists

In Kotlin, we can easily join two lists using the plus() function.

This function concatenates the two lists and returns a new list with the combined elements.

Here’s an example code snippet that demonstrates how to join two lists in Kotlin:

fun main() {
    val list1 = listOf("apple", "banana", "orange")
    val list2 = listOf("grape", "watermelon", "pineapple")

    val combinedList = list1.plus(list2)

    println("Combined List: $combinedList")
}

In the above code, we first create two lists list1 and list2 with some elements.

Then we call the plus() function on list1 and pass list2 as a parameter. The result of this operation is stored in combinedList.

Finally, we print the contents of combinedList using println().

When you run the above code, you will get the following output:

Combined List: [apple, banana, orange, grape, watermelon, pineapple]

As you can see, the two lists are successfully joined into a single list.

In addition to the plus() function, Kotlin provides several other ways to concatenate or merge lists.

For example, we can use the addAll() function to add all the elements of one list to another list.

We can also use the union() function to merge two lists while eliminating duplicate elements.

In conclusion, joining two lists in Kotlin is a simple task that can be accomplished using the plus() function.

This function is easy to use and can be used to concatenate two lists with just a single line of code.
