Comparison operators

In Kotlin, there are various comparison operators that can be used to compare values ​​and produce Boolean results (“true” or “false”). Below are some of the most important comparison operators in Kotlin.

== equality operator: This operator is used to determine whether two values ​​are equal.

fun main() {
    val a = 10
    val b = 5
    val isEqual = a == b // Result: "false"
    println(isEqual)
}

The example above checks whether the value is from the variable a equal to the value of b is. Since they are not equal, the variable isEqual on false placed.

!= inequality operator: This operator is used to determine whether two values ​​are not equal. For example:

fun main() {
    val a = 10
    val b = 5
    val isNotEqual = a != b // Result: "true"
    println(isNotEqual)
}

This example checks whether the value of a not equal to the value of b is. Since they are unequal, the variable isNotEqual on true placed.

> Greater than operator: This operator is used to determine whether a value is greater than another value. For example:

fun main() {
    val a = 10
    val b = 5
    val isGreater = a > b // Result: "true"
    println(isGreater)
}

This example checks whether the value of the variable a greater than the value of b is. Since this is the case, the variable isGreater on true placed.

< Less than operator: This operator is used to determine whether a value is less than another value. For example:

fun main() {
val a = 10
val b = 5
val isLess = a < b // Result: "false"
println(isLess)
}

This example checks whether the value of a smaller than the value of b is. Since this is not the case, the variable isLess on false placed.

>= Greater than or equal operator: This operator is used to determine whether a value is greater than or equal to another value. For example:

fun main() {
    val a = 10
    val b = 5
    val isGreaterOrEqual = a >= b // Result: "true"
    println(isGreaterOrEqual)
}

This example checks whether the value of a greater than or equal to the value of b is. Since this is the case, the variable isGreaterOrEqual on true placed.

<= Less than or equal operator: This operator is used to determine whether a value is less than or equal to another value. For example:

 
fun main() { 
    val a = 10 
    val b = 5 
    val isLessOrEqual = a <= b // Result: "false" println(isLessOrEqual) 
} 

This example checks whether the value of a less than or equal to the value of b is. Since this is the case, the variable isLessOrEqual on false placed.
