Учитывая следующий код:
// это часть какого-то большого метода //
ArrayList<String> players = this.m_maze.getPlayers();
// define the first node to be the human player , and pop him from the list
// the rest of the nodes are the computer side
Iterator<String> iterator = players.iterator();
// human side
String humanPlayer = iterator.next();
// controller - start a game between the players , at least two players are playing
while (this.m_rounds > 0)
{
String[] choices = this.m_view.getChoiceFromUser();
int usersChoice = Integer.parseInt(choices[0]);
switch (usersChoice)
{
case 1: // then user chose to stay put
{
}
case 2: // then take the next step
{
// let the user make his move
this.m_maze = this.m_model.makeSomeMove(choices[1],humanPlayer,true);
// print out the maze for visualization
this.m_view.drawMaze(m_maze);
// controller - reduce the number of current rounds for the current game
this.m_rounds--;
}
case 31: // then user asked for the closest treasure
{
// put some code here later on
}
case 32: // then user asked for the nearest room
{
// put some code here later on
}
} // end switch case
} // end while
(1). Как я могу поместить в humanPlayer
первый элементArrayList после каждого вызова makeSomeMove
?
(2). Можно ли повторно использовать итератор?так как я использую hasnext()
и next()
...?
Большое спасибо Рон
