# Kotlin – Check if Two Numbers are Equal

## Check if two numbers are equal in Kotlin

In Kotlin, you can check if given two numbers are equal using Equal-to Operator.

For example, if `a` and `b` are the given two numbers, then the expression to check if these two numbers are equal is

``a == b``

We can use this as a condition in if-else statement.

## Examples

### Check if 20 and 20 are equal numbers

In the following example, we take two numbers in `a` and `b`, say 20 and 20 respectively, and programmatically check if these two numbers are equal.

Kotlin Program

``````fun main() {
val a = 20
val b = 20

if (a == b) {
println("\$a and \$b are equal numbers.")
} else {
println("\$a and \$b are not equal numbers.")
}
}``````

Output

``20 and 20 are equal numbers.``

### Check if 35 and 84 are equal numbers

In the following example, we take two numbers in `a` and `b`, say 35 and 84 respectively, and programmatically check if these two numbers are equal.

Kotlin Program

``````fun main() {
val a = 35
val b = 84

if (a == b) {
println("\$a and \$b are equal numbers.")
} else {
println("\$a and \$b are not equal numbers.")
}
}``````

Output

``35 and 84 are not equal numbers.``
