📌 Information & Algorithm

Given Input:

Enter 10 characters:
q w e r t y u i o p

Expected Output:

Enter 10 characters:
q w e r t y u i o p

Original Array:
q w e r t y u i o p
Sorted Array:
e i o p q r t u w y Press any key to continue . . .

💻 Program Code

import java.util.Scanner;

public class BubbleSortCharacters {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        char[] arr = new char[10];

        // Accept 10 characters from the user
        System.out.println("Enter 10 characters:");
        for (int i = 0; i < 10; i++) {
            arr[i] = scanner.next().charAt(0);
        }

        // Store the original array for display
        char[] originalArr = arr.clone();

        // Bubble Sort Algorithm
        for (int i = 0; i < arr.length - 1; i++) {
            for (int j = 0; j < arr.length - 1 - i; j++) {
                if (arr[j] > arr[j + 1]) {
                    // Swap elements
                    char temp = arr[j];
                    arr[j] = arr[j + 1];
                    arr[j + 1] = temp;
                }
            }
        }

        // Display Original and Sorted Arrays
        System.out.println("\nOriginal Array:");
        for (char ch : originalArr) {
            System.out.print(ch + " ");
        }

        System.out.println("\nSorted Array:");
        for (char ch : arr) {
            System.out.print(ch + " ");
        }

        scanner.close();
    }
}

📘 Explanation

How It Works

The program accepts 10 characters from the user.
It stores the original array using clone().
The Bubble Sort algorithm sorts the characters in ascending order.
The program displays both the original and sorted arrays.

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
