If an unchecked exception is specified in throws — will there be an error?

In Java, if you specify an unchecked exception, such as a subclass of RuntimeException, in the throws clause of a method declaration, the compiler will not produce an error. This is because unchecked exceptions do not require mandatory handling or declaration. For example:

public void myMethod() throws NullPointerException {
    // code
}

Such code compiles without issues. However, it is generally not customary to specify unchecked exceptions in throws, as it does not add informativeness and does not require handling by the caller.
