What are some examples of checked exceptions in Java?

Checked exceptions in Java are exceptions that must be either caught or declared in the method signature. Examples include IOException, SQLException, and ClassNotFoundException.

Can you explain IOException with an example?

Sure! IOException occurs when there is a failure during input or output operations. For example, trying to read a file that doesn't exist will throw an IOException.

What about SQLException?

SQLException is thrown when there is an error accessing a database. For instance, if you try to execute a query on a closed connection, it will throw a SQLException.

How do I handle these exceptions in my code?

You can handle checked exceptions using try-catch blocks. For example:

try {
    // code that may throw an exception
} catch (IOException e) {
    // handle exception
}
