如何为每个循环更改for循环

Question

CODE：

for (int i =0; i<=10; i++) {
System.out.println(movieasArrayList.get(i).getID() + " " + movieasArrayList.get(i).getAction()); 
  }

问题：

将此for-loop更改为for-each loop，以便为所有电影（不仅仅是前11位）执行相同的任务。

任何帮助将不胜感激!!

Answer 1

java中的for-each循环结构如下：

// works with collections and arrays, everything
// that has an iterator
Collection<Object> c = new Collection<Object>();
for (Object i : c) {
    // do code
}

对你来说，这看起来像这样：

// I don't know what your movieArrayList contains
for (Movie i : movieArrayList) {
    System.out.println(i.getId() + " " +  i.getAction());
}

希望这有帮助！
