Kotlin equivalent of Java's equalsIgnoreCase
Java provides a String method called equalsIgnoreCase() which helps developers to compare two strings on the basis of their content. This comparison is case-insensitive, that is, it ignores whether the strings are in uppercase or lowercase and just compares the string values. In this article, we will see how we can implement the same functionality in Kotlin.
Example – equalsIgnoreCase in Java
The following example demonstrates how equalsIgnoreCase() works in Java.
public class MyClass {
public static void main(String args[]){
String s1="TutorialsPoint";
String s2="tutorialspoint";
System.out.println("String 1: " + s1);
System.out.println("String 2: " + s2);
// Strings match as we ignore the case
System.out.println("Strings match? : " + s1.equalsIgnoreCase(s2));
}
}Output
It will produce the following output −
String 1: TutorialsPoint String 2: tutorialspoint Strings match? : true
Example – equalsIgnoreCase in Kotlin
Now, let's check how we can implement the same concept in Kotlin.
fun main(args: Array<String>) {
val t1 = "TutorialsPoint.com";
val t2 = "TutorialsPoint";
val t3 = "tutorialspoint";
// false as the strings do not match
println("String 1: " + t1)
println("String 2: " + t2)
println("String 3: " + t3)
// comparing t1 and t2
println("Strings 1 and 2 match? : " + t1.equals(t2, ignoreCase = true));
// comparing t2 and t3
// both the strings match as we ignore their case
println("Strings 2 and 3 match? : " + t2.equals(t3, ignoreCase = true));
}Output
It will produce the following output −
String 1: TutorialsPoint.com String 2: TutorialsPoint String 3: tutorialspoint Strings 1 and 2 match? : false Strings 2 and 3 match? : true
