The constructor will need to call the
<link linkend="constructorFromJava">parent constructor</link>.
! It is not fully possible to override a Nice multi-method in a Java
! program. However, provided that the method is compiled as an
! instance method, as specified <link
! linkend="compilationMethods">above</link>, you can override
! that method as usual for Java. That is, only the first
! (implicit) argument can be used to perform the override.
