About Swift

Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. and the open-source community.

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: Swift vs Java

Palindrome Check in Swift

func isPalindrome(_ str: String) -> Bool {
    let clean = str.lowercased().filter { $0.isLetter || $0.isNumber }
    return clean == String(clean.reversed())
}

# Example usage
print(isPalindrome("A man, a plan, a canal: Panama")) // true
print(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: Swift vs Java

Bubble Sort in Swift

func bubbleSort(_ arr: inout [Int]) {
    let n = arr.count
    for i in 0..<n {
        for j in 0..<(n - i - 1) {
            if arr[j] > arr[j + 1] {
                arr.swapAt(j, j + 1)
            }
        }
    }
}

# Example usage
var arr = [64, 34, 25, 12, 22, 11, 90]
bubbleSort(&arr)
print(arr)

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));
    }
}
