What is the exception hierarchy in Java?

In Java, exceptions are categorized into two main types: checked and unchecked exceptions. Checked exceptions must be declared in a method's throws clause, while unchecked exceptions do not.

Can you give me examples of checked and unchecked exceptions?

Sure! An example of a checked exception is IOException, while an example of an unchecked exception is NullPointerException.

How do I handle exceptions in Java?

You can handle exceptions in Java using try-catch blocks. Place the code that might throw an exception in the try block, and handle the exception in the catch block.

What happens if I don't handle an exception?

If you don't handle an exception, it will propagate up the call stack, and if it reaches the main method, the program will terminate.
