When should I use the finally-block in Java's try-catch-finally

Question

When should I use code snippet A instead of snippet B (i.e. what are the benefits of using snippet A)?:

Snippet A:

try {
    // codebloc         


        

Answer 1

You must almost always use the snippet with finally block when you have resources that needs clean up in both successful or error scenarios. A typical example is the jdbc connection object which should always be closed (clean up) in the finally block.
