如何在Java的Eclipse中自动创建抽象类的子类？

Question

say I had an abstract java class in eclipse. Now I want to create some subclasses of that abstract class. Is there a way to create them automatically where I just enter the name of the class and eclipse creates the necessary methods?

I thought that I would find it in the "Refactor" option but I didn't. Can someone help me?

Answer 1

Yes, create a new class using Right Click (on the package where you want to create the class) > New > Class , and in the SuperClass field, you can select your abstract class. Be sure that the checkbox Which method stubs would you like to > Inherited abstract methods is checked.

If you have already created your class, you can make it extend you abstract class by hand, and use Right Click (on the source code) > Source > Override/Implement Methods... and choose which methods you want to implement (if they are not already implemented).

An other way to do it, is to extend your abstract class by hand, and use the Quick Fix provided by Eclipse to Add unimplemented methods . You can call the Quick Fix tooltip by highlighting the error and using Ctrl+1 , or by clicking on the error icon on the left of the code.

Answer 2

Use the New Class as normal but then specify your abstract class as the Superclass . Then check Which methods stubs would you like to create -> inherited abstract methods

Answer 3

只需创建一个扩展抽象类的类，默认情况下eclipse将添加所有未实现的方法
