But this link for Java(Android) Language.I want to use kotlin Language... I am using OkHttp library

 val client = OkHttpClient()
 val time = client.connectTimeoutMillis() // it's get only methood but i looking for method for set Timeout
and my trouble is I cannot find how to set connection timeout and socket timeout For Kotlin.
                You should do the same thing. Kotlin has little difference in this aspect comparing to Java. Just call OkHttp.Builder, configure it with needed timeouts and build an object. The code must be the same as for Java.

                The language doesn't matter in this case. Just do val client = OkHttp.Builder().connectionTimeout(10, TimeUnit.SECONDS).writeTimeout(10, TimeUnit.SECONDS).build()

                The problem with the question you linked is not that it is Java and you are using Kotlin but that the accepted answer is for OkHttp2 - but other answers are for OkHttp3

A Builder is required, there are no setters available. With OkHttp 3.9.1 you can do this:
val client = OkHttpClient.Builder()
    .connectTimeout(10, TimeUnit.SECONDS)
    .writeTimeout(10, TimeUnit.SECONDS)
    .readTimeout(30, TimeUnit.SECONDS)
    .build()
Not much different than the accepted answer, but it seems it is best to return the same OkHttpClient to avoid memory leaks. 
sealed class ClientBuilder {
    companion object {
        val plainClient: OkHttpClient by lazy {
             OkHttpClient
                .Builder()
                .connectTimeout(5, TimeUnit.SECONDS)
                .readTimeout(3, TimeUnit.SECONDS)
                .writeTimeout(3, TimeUnit.SECONDS)
                .build()
    fun client() : OkHttpClient {
        return plainClient
