Kotlin also allows equal to equal to as a comparator operator . Let’s start with the “==” operator. This operator can be used to check if the strings are structurally equal. It’s the equivalent of using the equals method in Java.2 Eki 2019

In Kotlin there are two types of equality: Structural equality ( == – a check for equals() ) Referential equality ( === – two references point to the same object)

Compares this object with the specified object for order . Returns zero if this object is equal to the specified other object, a negative number if it’s less than other, or a positive number if it’s greater than other.

Java String equalsIgnoreCase() Method This method returns true if the strings are equal, and false if not. Tip: Use the compareToIgnoreCase() method to compare two strings lexicographically, ignoring case differences .

Some of them are:

ignoreCase – true to ignore character case when comparing strings. By default false . Returns true if this character is equal to the other character, optionally ignoring character case. Two characters are considered equal ignoring case if Char.
