How can I handle exceptions in a Java application?

How can I handle exceptions in a Java application?

In Java, you can handle exceptions using try-catch blocks. Wrap the code that may throw an exception in a try block, and handle the exception in the catch block.

Can you give me an example of using try-catch?

Sure! Here's a simple example:

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

What about multiple exceptions?

You can catch multiple exceptions by using multiple catch blocks or a multi-catch block like this:

try {
    // some code
} catch (IOException | SQLException e) {
    e.printStackTrace();
}

How do I create a custom exception?

To create a custom exception, extend the Exception class and provide a constructor. For example:

public class MyCustomException extends Exception {
    public MyCustomException(String message) {
        super(message);
    }
}
