About Ruby

Ruby is an interpreted, high-level, general-purpose programming language. It was designed and developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan.

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: Ruby vs Java

Palindrome Check in Ruby

def palindrome?(str)
    clean = str.downcase.gsub(/[^a-z0-9]/, '')
    clean == clean.reverse
end

# Example usage
puts palindrome?("A man, a plan, a canal: Panama") # true
puts palindrome?("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: Ruby vs Java

Bubble Sort in Ruby

def bubble_sort(arr)
    n = arr.length
    n.times do |i|
        (n - i - 1).times do |j|
            if arr[j] > arr[j + 1]
                arr[j], arr[j + 1] = arr[j + 1], arr[j]
            end
        end
    end
    arr
end

# Example usage
arr = [64, 34, 25, 12, 22, 11, 90]
puts bubble_sort(arr.dup).inspect

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));
    }
}
