About Kotlin
Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference.
About Java
Java is a high-level programming language developed by Sun Microsystems. It was originally designed for developing programs for set-top boxes and handheld devices, but later became a popular choice for creating web applications.
Palindrome Check Example: Kotlin vs Java
Palindrome Check in Kotlin
fun isPalindrome(str: String): Boolean {
val clean = str.lowercase().filter { it.isLetterOrDigit() }
return clean == clean.reversed()
}
fun main() {
println(isPalindrome("A man, a plan, a canal: Panama")) // true
println(isPalindrome("race a car")) // false
}Palindrome Check in Java
public class PalindromeChecker {
public static boolean isPalindrome(String str) {
String cleanStr = str.toLowerCase().replaceAll("[^a-z0-9]", "");
return cleanStr.equals(new StringBuilder(cleanStr).reverse().toString());
}
public static void main(String[] args) {
System.out.println(isPalindrome("A man, a plan, a canal: Panama")); // true
System.out.println(isPalindrome("race a car")); // false
}
}Bubble Sort Example: Kotlin vs Java
Bubble Sort in Kotlin
fun bubbleSort(arr: IntArray) {
val n = arr.size
for (i in 0 until n) {
for (j in 0 until n - i - 1) {
if (arr[j] > arr[j + 1]) {
val temp = arr[j]
arr[j] = arr[j + 1]
arr[j + 1] = temp
}
}
}
}
fun main() {
val arr = intArrayOf(64, 34, 25, 12, 22, 11, 90)
bubbleSort(arr)
println(arr.joinToString(" "))
}Bubble Sort in Java
public class BubbleSort {
public static void bubbleSort(int[] arr) {
int n = arr.length;
for (int i = 0; i < n; i++) {
for (int j = 0; j < n - i - 1; j++) {
if (arr[j] > arr[j + 1]) {
int temp = arr[j];
arr[j] = arr[j + 1];
arr[j + 1] = temp;
}
}
}
}
public static void main(String[] args) {
int[] arr = {64, 34, 25, 12, 22, 11, 90};
bubbleSort(arr);
System.out.println(Arrays.toString(arr));
}
