Java: try catch finally
Answer
Use 'finally' block to release resources. Frame the concept in practical terms so you can explain it during interview discussion.
To ensure resources like files or database connections are released after usage, use a 'finally' block. This block guarantees execution after the 'try' and 'catch' blocks, allowing for cleanup actions regardless of whether an exception was thrown. For instance, closing a database connection should be in a 'finally' block.
