Collections: Break the list of items to sub‐chunks of items

Code

data class Country(val name: String, val isDemocracy: Boolean)
val countriesList = mutableListOf(
    Country(name = "USA", isDemocracy = true),
    Country(name = "Australia", isDemocracy = true),
    Country(name = "Russia", isDemocracy = false),
    Country(name = "England", isDemocracy = true),
    Country(name = "North Korea", isDemocracy = false)
)


fun main(args: Array<String>) {
    val output = countriesList.chunked(2)
    println("Result-> $output")
}

Output

Result-> [[Country(name=USA, isDemocracy=true), Country(name=Australia, isDemocracy=true)], [Country(name=Russia, isDemocracy=false), Country(name=England, isDemocracy=true)], [Country(name=North Korea, isDemocracy=false)]]
