多少种方法在那里让code输出本身？

How many ways are there to let the code output itself?

例如，下面写的code，

For example, write the code below,

public class Test
{
   public static void main(String[] args)
   {
      // some code
   }
}

要输出本身

public class Test
{
   public static void main(String[] args)
   {
      // some code
   }
}

（任何编程语言被接受）

(Any programming language is accepted)
