Description

The BubbleSortStrings class contains a main method that:

1. Initializes an array of strings.
2. Displays the original array.
3. Sorting the array using the bubble sort algorithm.
4. Displays the sorted array.

The bubble sort algorithm compares adjacent elements and swaps them if they are in the wrong order, repeating this process until the array is sorted.

Technologies

• Java 17
• Sorting algorithm. (Bubble Sort)
• Arrays

Usage Examples

BubbleSortStrings class:

public class BubbleSortStrings {
    public static void main(String[] args) {
        String[] message = {
                "I", "am", "sorting", "an",
                "array", "of", "strings"
        };

        int a, b;
        String t;
        int size;

        size = message.length; // number of elements to sort

        // Display the original array
        System.out.print("Original array");
        for (int i = 0; i < size; i++)
            System.out.print(" " + message[i]);
        System.out.println();

        //Bubble sort for strings
        for (a = 1; a < size; a++)
            for (b = size - 1; b >= a; b--) {
                // If the order is not followed, then swap the elements
                if (message[b - 1].compareTo(message[b]) > 0) {
                    t = message[b - 1];
                    message[b-1] = message[b];
                    message [b] = t;
                }
            }
        //Display sorted array
        System.out.print("Sorted array: ");
        for (int i = 0; i < size; i++)
            System.out.print(" " + message[i]);
        System.out.println();
    }
}
