我记不清了，大概是这样的:

Person p = new Person("John", "Doe", "male");
Collection women = new ArrayList();
women.insert(p.getTail());

这是肮脏的代码;)

// All this code is yours, except gedit()...attempt no modifications there.

else
{
    //error situation
}

/**
 * If you don't understand this code, you should be flipping burgers instead.
 */

$this->getSelect()->where ('main_table.product_id = -1'); // Mom, Dad... sorry

v.bpc     := v.pc;  -- Remember to jump back
v.baccu   := accu;  -- Yo dawg, heard you like runing instructions
                    -- so I took backup of your accu so you can run
                    -- instructions while you run instructions.
