Welcome to this beginner-friendly Java programming tutorial! In this video, I’ll show you how to write a Java program to replace all 0s with 1s in an integer input by the user. This is a simple yet effective way to understand Java string manipulation, loops, and basic conditional statements—essential skills for anyone starting out in Java programming.

📝 Problem Description:
Given an integer, our task is to replace every 0 in the number with 1. This is a common beginner problem in programming that helps you strengthen your understanding of loops and conditional logic in Java.

🔎 Solution Overview:
Convert the Integer to a String: First, we convert the number to a string to make it easy to examine each digit individually.
Loop through Each Character: Using a for loop, we iterate over each character in the string.
Check and Replace: If a character is 0, we replace it with 1. Otherwise, we simply keep the original character.
Display the Result: Once all 0s are replaced, we display the final transformed number.
This approach makes it easy to handle numbers of any length and simplifies the replacement operation. We’ll be using Java’s String and char functionalities, making this a great learning experience for beginners.

💻 Code Walkthrough:
In the code, we use:

Scanner to get user input,
Integer.toString() to convert an integer to a string, and
String concatenation to build the final number with 1s in place of 0s.
Whether you’re preparing for coding interviews or just practicing, this problem offers great practice in handling strings and conditional operations in Java. Watch the entire video to see the code in action!
