如何在Eclipse中创建一个子类Java EE？ [英] how to create a subclass in Eclipse Java EE?

问题描述

在演讲期间，我的教授很快在Eclipse中创建了一个子类。结果将扩展关键字添加到子类中。我没看到他点击了什么按钮。有谁知道我应该在哪里点击？ （我想他右键点击了当前课程包的资源管理器，然后是新的==>类，然后我输入什么选择）请帮助

During lecture, my professor very quickly created a subclass in Eclipse. The result has the "extend" keyword added to the subclass. I didn't see what buttons he clicked. Does anyone know where should i click? (i think he right clicked on the current class in the package explorer, then New ==> class, then im lost on what to select) please help

推荐答案

当您查看要子类的类时，打开类型层次结构（按F4）。右键单击parent-to-be类，然后在菜单中转到new - > class（或Ctrl-n，class）。

When you are viewing the class you want to subclass, open Type Hierarchy (press F4). Right click on the parent-to-be class, and in the menu go to new -> class ( or Ctrl-n , class ).
