What is the purpose of the finally clause of a try-catch-finally statement

by

The finally clause is used to provide the capability to execute code no matter whether or not an exception is thrown or caught.

The purpose of the finally clause in a try-catch-finally statement in Java is to define a block of code that will be executed whether an exception is thrown or not. This block of code is guaranteed to run, regardless of whether an exception occurs within the try block or not.

The finally block is typically used for cleanup operations or releasing resources that were acquired in the try block. For example, closing files, releasing database connections, or closing network sockets are common use cases for the finally block.

Here’s an example:

java
try {
// Code that may throw an exception
// ...
} catch (Exception e) {
// Exception handling code
// ...
} finally {
// Code that will always be executed
// Cleanup operations, resource release, etc.
}

In this example, whether an exception occurs or not, the code inside the finally block will be executed.
