Kotlin Program Comparing Strings

package net.javaguides.kotlin.examples

fun main(args: Array < String > ) {

    val s1 = "SourceCodeExamples"
    val s2 = "sourcecodeexamples"

    if (s1 == s2) {

        println("Strings are equal")
    } else {

        println("Strings are not equal")
    }

    println("Ignoring case")

    val res = s1.compareTo(s2, true)

    if (res == 0) {

        println("Strings are equal")
    } else {

        println("Strings are not equal")
    }
}

Output:
Strings are not equal
Ignoring case
Strings are equal
