Exception Handling - try catch throws
Exception handling is a mechanism to handle runtime errors, ensuring a program can deal with unexpected issues without crashing. It involves the use of try, catch, and throw constructs
Key Components
1. try Block
A block of code where you write the logic that might cause an exception.
If an exception occurs, it is "thrown" and execution jumps to the corresponding catch block.
2. catch Block
Handles the exception that occurs in the try block.
You can specify the type of exception you want to catch and provide code to recover from or log the error.
3. throw Keyword
Used to explicitly generate an exception.
It can be used to signal an error or pass control to a catch block.
4. finally Block (Optional)
Contains code that will always execute, regardless of whether an exception occurs or not. Often used for cleanup tasks (e.g., closing files, releasing resources).
