What is the difference between throw and throws in Java?

What is the difference between throw and throws in Java?

In Java, 'throw' is used to explicitly throw an exception, while 'throws' is used in method signatures to declare that a method can throw exceptions.

Can you give me an example of how to use throw?

Sure! You can use 'throw' like this:

throw new IllegalArgumentException("Invalid argument!");

This will throw an IllegalArgumentException when executed.

And how about using throws in a method?

You can declare a method that throws an exception like this:

public void myMethod() throws IOException {
    // method implementation
}

This indicates that myMethod can throw an IOException.

Are there any best practices for using throw and throws?

Yes, it's best to use 'throw' for specific exceptions that you want to handle immediately, and 'throws' for methods that may encounter exceptions that you want to handle at a higher level.
