If you've worked with Java, you've certainly encountered exceptions.
But do you know the difference between checked and unchecked exceptions? ๐ค
๐ Checked Exceptions: These are exceptions that the compiler forces you to handle. They typically represent conditions that can occur due to factors outside the program's control, like network issues ๐ or I/O failures ๐. For example, when trying to open a file that doesnโt exist, a FileNotFoundException is thrown.
As a developer, you must either handle these exceptions (using a try-catch block) or declare that the method can throw them (using throws in the method signature).
๐ Unchecked Exceptions: These exceptions are subclasses of RuntimeException and are not checked by the compiler. They usually indicate programming errors, such as trying to access an array index out of bounds (ArrayIndexOutOfBoundsException) ๐ or dividing by zero (ArithmeticException).
Since they aren't mandatory to handle, you can choose to catch them or let them propagate.
โ๏ธ When to Use Which?
Use checked exceptions for situations where failure is expected and recoverable ๐.
Use unchecked exceptions to indicate programming errors that ideally should be fixed rather than handled ๐ ๏ธ.
Understanding this difference helps you write more robust code ๐ช and make better decisions when dealing with errors. How do you usually handle exceptions in your code? Share your experiences in the comments! ๐ฌ
