What are Java exceptions and how do I handle them?

Java exceptions are events that disrupt the normal flow of a program. They can be handled using try-catch blocks.

Can you give me an example of a try-catch block?

Sure! Here's a simple example:

try {
    int result = 10 / 0;
} catch (ArithmeticException e) {
    System.out.println("Cannot divide by zero!");
}

What are checked and unchecked exceptions?

Checked exceptions are checked at compile-time, while unchecked exceptions are checked at runtime. Examples include IOException and NullPointerException.

How can I create my own exception in Java?

You can create your own exception by extending the Exception class or RuntimeException class, depending on whether you want it to be checked or unchecked.
