🚀 *Topics Covered in This Video:*
🔹 *What is If Statement?*
Learn how conditions control the flow of a program using true/false logic.
🔄 *Types of If Statements:*

✔ *If-Else Statement* – Used when there are two possible outcomes (true/false).
✔ *If-Else If Ladder* – Used to check multiple conditions in sequence.
✔ *Nested If Statement* – An if statement inside another if for multiple conditions.

🔹 *Short-Circuit Concept* – Java avoids unnecessary evaluations, helping prevent errors.
🔹 *String Comparison* – Always use `.equals()` instead of `==` for comparing strings.
🔹 *Null Safety* – Check for null values before calling methods to avoid exceptions.
🌍 *Real-Time Example:*
