What are the advantages and disadvantages of using checked exceptions in code?

Checked exceptions in Java are exceptions that the compiler requires to be either caught or declared in the method signature with throws.

Advantages:

• Explicitly indicates possible errors, increasing code reliability.
• Forces developers to consider error handling, reducing the chance of missing important exceptional situations.

Disadvantages:

• Increases code volume due to handling or propagating exceptions.
• Can lead to cluttered method signatures and complicate usage.
• Sometimes forces writing empty catch blocks or just rethrowing exceptions, reducing usefulness.

In summary, checked exceptions are useful for critical errors that can and should be handled, but their overuse can impair code readability and maintenance.
