How do I handle exceptions in Java effectively?

In Java, you can handle exceptions using try-catch blocks. You can also create custom exceptions for specific error handling.

What is the difference between checked and unchecked exceptions?

Checked exceptions are checked at compile-time, while unchecked exceptions are checked at runtime. You must handle checked exceptions.

Can you give an example of a custom exception?

Sure! You can create a custom exception by extending the Exception class. For example:

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

How can I ensure that resources are closed properly?

You can use the try-with-resources statement, which automatically closes resources when done. For example:

try (BufferedReader br = new BufferedReader(new FileReader("file.txt"))) {
    // Read file
}
