Introduction to Apex If-Else Statements
The if-else statement in Apex is a fundamental control structure that allows you to execute a block of code based on a boolean condition. This is crucial for making decisions in your code, especially when working with Salesforce data. By using if-else statements, you can perform different actions based on conditions, making your applications more dynamic and responsive.

Sometimes, your logic might require nested if-else statements, where an if-else statement is placed inside another. This can be useful for complex decision-making:
Conclusion
The if-else statement is a versatile tool in Apex programming, allowing for nuanced decision-making based on conditions. Whether you're checking a single condition or multiple, using if-else statements effectively can greatly enhance the functionality of your Salesforce applications. Experiment with these structures to better understand how they can be applied to your specific use cases.
