1 Comparison of Strings in Kotlin

In this example,

  1. We create two strings named str1 and str2 with different values.
  2. We compare the strings using the == operator.
  3. The comparison returns true if the strings are equal, and false otherwise.
  4. Finally, we print the result of the comparison.

Kotlin Program

// Comparison of Strings in Kotlin
fun main() {
    val str1 = "Hello"
    val str2 = "hello"
    val result = str1 == str2
    println("Strings are equal: $result")
}
