Certainly! Here are a few simple Kotlin exercises along with examples:
Problem: Write a Kotlin program to calculate the area of a rectangle given its length and width.
Example Solution:
fun calculateArea(length: Double, width: Double): Double {
return length * width
}
fun main() {
val length = 5.0
val width = 3.0
val area = calculateArea(length, width)
println("The area of the rectangle is: $area")
}
Problem: Write a Kotlin program to check if a given number is even or odd.
Example Solution:
fun checkEvenOrOdd(number: Int): String {
return if (number % 2 == 0) "Even" else "Odd"
}
fun main() {
val number = 7
val result = checkEvenOrOdd(number)
println("$number is $result")
}
Problem: Write a Kotlin program to find the maximum of three given numbers.
Example Solution:
fun findMaximum(a: Int, b: Int, c: Int): Int {
return maxOf(a, b, c)
}
fun main() {
val num1 = 10
val num2 = 20
val num3 = 15
val max = findMaximum(num1, num2, num3)
println("The maximum of $num1, $num2, and $num3 is: $max")
}
Problem: Write a Kotlin program to check if a given year is a leap year.
Example Solution:
fun isLeapYear(year: Int): Boolean {
return (year % 4 == 0 && year % 100 != 0) || (year % 400 == 0)
}
fun main() {
val year = 2024
val leap = if (isLeapYear(year)) "is" else "is not"
println("$year $leap a leap year")
}
These exercises cover basic concepts like functions, conditional statements, and mathematical operations in Kotlin. They are a good starting point for practicing Kotlin programming.
