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.

About C#

C# is a general-purpose, multi-paradigm programming language encompassing strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented, and component-oriented programming disciplines.

Palindrome Check Example: Java vs C#

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
    }
}

Palindrome Check in C#

using System;
using System.Linq;

class Program {
    static bool IsPalindrome(string str) {
        string clean = new string(str.ToLower()
            .Where(c => Char.IsLetterOrDigit(c))
            .ToArray());
        return clean.SequenceEqual(clean.Reverse());
    }
    
    static void Main() {
        Console.WriteLine(IsPalindrome("A man, a plan, a canal: Panama")); // True
        Console.WriteLine(IsPalindrome("race a car")); // False
    }
}

Bubble Sort Example: Java vs C#

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));
    }
}

Bubble Sort in C#

using System;

class Program {
    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;
                }
            }
        }
    }
    
    static void Main() {
        int[] arr = { 64, 34, 25, 12, 22, 11, 90 };
        BubbleSort(arr);
        Console.WriteLine(string.Join(" ", arr));
    }
}
