Example: Sort String using Manual Bubble Sort in Java

// Sort String using Manual Bubble Sort
// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        String inputString = "zebra";
        System.out.println("Original String: " + inputString);

        char[] charArray = inputString.toCharArray();
        int n = charArray.length;

        // Step 1: Implement Bubble Sort algorithm
        // Outer loop for passes
        for (int i = 0; i < n - 1; i++) {
            // Inner loop for comparisons and swaps
            for (int j = 0; j < n - i - 1; j++) {
                // If current character is greater than the next, swap them
                if (charArray[j] > charArray[j + 1]) {
                    char temp = charArray[j];
                    charArray[j] = charArray[j + 1];
                    charArray[j + 1] = temp;
                }
            }
        }

        // Step 2: Convert the manually sorted character array back to a string
        String sortedString = new String(charArray);
        System.out.println("Sorted String: " + sortedString);
    }
