Example: Replace Zeros with Ones using String Conversion in Java

// Replace Zeros with Ones using String Conversion
import java.util.Scanner;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        // Step 1: Get integer input from the user
        System.out.print("Enter an integer: ");
        int originalNumber = scanner.nextInt();

        // Step 2: Convert the integer to a string
        String numberAsString = String.valueOf(originalNumber);

        // Step 3: Replace all '0' characters with '1' characters
        String modifiedString = numberAsString.replace('0', '1');

        // Step 4: Convert the modified string back to an integer
        int modifiedNumber = Integer.parseInt(modifiedString);

        // Step 5: Print the result
        System.out.println("Original number: " + originalNumber);
        System.out.println("Modified number: " + modifiedNumber);

        scanner.close();
    }
