Kotlin If..Else..Else If decision making

Kotlin supports below decision making statements:

“If” statements: where if a condition is true it is used to specify execution for a block of code.
“Else” statements: where if the same condition is false it specifies the execution for a block of code.
“Else if” statements: this specifies a new test if the first condition is false.

Syntax of If statement

if (condition) {
  // block of code to be executed if the condition is true
} else if (another condition){
 // code to be executed for another condition
} else if (another condition){
 // code to be executed for another condition
} else if (another condition){
 // code to be executed for another condition
} else {
 // default code execution if not met in above statements
}

Example of if, Else, Else if in Kotlin

fun main() {
  val time = 22
  if (time < 10) {
    println("Good morning.")
  } else if (time < 20) {
    println("Good day.")
  } else {
    println("Good evening.")
  }
}

Output

Good morning.
