将构造函数替换为工厂方法   重构让您隐藏一个构造函数，并用一个返回类的新实例的静态方法替换它。

Procedure:

1. 请将文本光标放在编辑器中的类构造函数处，然后按 `Alt+Enter` (Windows), `⌥ ⏎` (macOS), `⌥ ⏎` (IntelliJ IDEA Classic (macOS)), `⌥ ⏎` (macOS System Shortcuts), `Alt+Enter` (XWin), `Alt+Enter` (GNOME), `Alt+Enter` (KDE), `Alt+Enter` (Emacs), `Alt+Enter` (Sublime Text), `⌥ ⏎` (Sublime Text (macOS)), `Alt+Enter` (Visual Studio), `⌥ ⏎` (Visual Studio (macOS)), `Alt+Enter` (NetBeans), `Ctrl+1` (Eclipse), `⌘ 1` (Eclipse (macOS))。

2. 从可用的上下文操作列表中选择   将构造函数替换为工厂方法  。

3. 在编辑器中，指定工厂方法的名称。
