I am new to java so maybe this is very trivial question.

But I just noticed that when i declared 

List myList = new ArrayList();

Eclipse IDE gave me bunch of options for "List" error.

Mainly.. the top 2 one got me curious.

What is the difference if I use java.awt vs java.utils ??

java.awt.List is List component (like drop down list), it not a collection/datastructure.

What is the difference if I use java.awt vs java.utils ??

You can't use List/Collection specific methods like iterator.

java.awt.List is an awt component. Don't use it in your case. You need java.util.List.

AWT 或抽象窗口工具包是 java 中的 GUI 工具包，包含 2D 元素所需的类。awt.list 用于获取应用程序中的选择框/下拉列表。

在您的情况下使用 util.list 。
