Java: List of Checked & Unchecked Exceptions

Like most modern programming languages, Java includes the concept of exceptions to handle both errors and "exceptional events." When an exception occurs in your code, it disrupts the normal instruction logic and abnormally terminates the process.

However, with a little foresight and code, you can often handle these exceptions gracefully, allowing your code to continue running and providing insight for tracking down the root cause of the unexpected result.

Below we have compiled a list of Checked and UncheckedJava exceptions you would likely encounter, with links to their corresponding guide on how best to implement them.
