What is the Java Exception Hierarchy?

Can you explain the Java Exception Hierarchy?

Sure! The Java Exception Hierarchy is a structured way of categorizing exceptions in Java. It starts with the Throwable class, which has two main subclasses: Error and Exception.

What are the differences between Error and Exception?

Errors are serious issues that a reasonable application should not try to catch, like OutOfMemoryError. Exceptions are conditions that a program might want to catch, like IOException.

Can you give examples of checked and unchecked exceptions?

Absolutely! Checked exceptions are those that must be declared in a method's throws clause, like SQLException. Unchecked exceptions, like NullPointerException, do not require this.

How can I handle exceptions in Java?

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