/**
 * This class provides the validation mechanism for Swing components. GUIs often
 * need to ensure that the components are in a valid state before allowing the
 * user to navigate the input focus. To do this, clients create a subclass of
 * {@code InputVerifier} and, using {@code JComponent}'s
 * {@code setInputVerifier} method, attach an instance of their subclass to
 * the {@code JComponent} which is the source of the focus transfer operation.
 * The {@code InputVerifier} also provides the possibility to validate against
 * the target of the focus transfer which may reject the focus.
 * Before focus is transferred from the source Swing component to the target
 * Swing component, the input verifier's
 * {@code shouldYieldFocus(source, target)} method is called. Focus is
 * transferred only if that method returns
 * {@code true}.
 * <p>
 * The following example has two text fields, with the first one expecting
 * the string "pass" to be entered by the user. If either that string is entered
 * in the first text field or the second text field contains "accept" string,
 * then the user can advance focus to the second text field by clicking in it or
 * by pressing TAB.
 * However, if another string is entered in the first text field and the second
 * text field does not contain "accept", then the user will be unable to
 * transfer focus to the second text field.
 *
 * <pre>

 *
 * // This program demonstrates the use of the Swing InputVerifier class.
 * // It creates two text fields; the first of the text fields expects the
 * // string "pass" as input, and will allow focus to advance to the second text
 * // field if either that string is typed in by the user or the second
 * // field contains "accept" string.
