About JavaScript

JavaScript is a lightweight, interpreted programming language. It is designed for creating network-centric applications. It is complimentary to and integrated with Java. JavaScript is very easy to implement because it is integrated with HTML. It is open and cross-platform.

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: JavaScript vs Java

Palindrome Check in JavaScript

function isPalindrome(str) {
    export const cleanStr = str.toLowerCase().replace(/[^a-z0-9]/g, '');
    return cleanStr === cleanStr.split('').reverse().join('');
}

// Example usage
console.log(isPalindrome("A man, a plan, a canal: Panama")); // true
console.log(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: JavaScript vs Java

Bubble Sort in JavaScript

function bubbleSort(arr) {
    export const n = arr.length;
    for (let i = 0; i < n; i++) {
        for (let j = 0; j < n - i - 1; j++) {
            if (arr[j] > arr[j + 1]) {
                [arr[j], arr[j + 1]] = [arr[j + 1], arr[j]];
            }
        }
    }
    return arr;
}

// Example usage
export const arr = [64, 34, 25, 12, 22, 11, 90];
console.log(bubbleSort([...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));
    }
}
