    dog()
    {
    for (int i=1;i<10;)
    System.out.println(i);
    }
    this function will never end ,it will print endless1 because it do nothing after the judgement i<10
    but why the function below runs ok?
    public static void print(Collection c)
    {
    for (Iterator x=c.iterator();x.hasNext();)
    System.out.print(x.next()+" ");
    System.out.println();
    }
    • The structure of a for-loop -jabber(jabber); 2001-3-15 {407} (#33374@0)
      for(...; ...; ???) {
      //code -------------
      }

      After the "code" is executed, ??? will be executed. So, if you like,
      you can change the above code into the following form

      for(...; ...; ) {
      //code -------------
      ???
      }

      I hope I have examplified the execution sequence here.

      I strongly suggest you grab a Java or C++ textbook and look into the
      explanation of for-loop. You will be OK.
