蚀。我可以删除Java类构造函数，使Eclipse自动重构吗？ [英] Eclipse. Can I delete a Java class constructor such that Eclipse automatically refactors?

问题描述

我有一个空的构造函数为一个类。我想删除构造函数，但有很多地方我有这样的东西，如：

Klass my_klass = new Klass（）;我想删除构造函数并让Eclipse自动重构，如果可以的话。结果如下：

Klass my_klass = new Klass（）;

Eclipse具有各种不错的重构功能。是否有这个？

解决方案

• 右键单击要删除的构造函数 - > Refactor - >更改方法签名。


• 删除所需的参数（在您的情况下都是这些），然后Eclipse将自动更改对该构造函数的所有调用。如果你已经有一个默认的构造函数，它会抱怨;只需按确定，它将给你一个编译错误，因为你有两个具有相同参数的构造函数，


• 合并或删除旧的，你有你想要的结果。 / li>
  

I have an empty constructor for a Class. I want to delete the constructor, but there are many places where I have things such as:

Klass my_klass = new Klass("");

I would like to delete the constructor and have Eclipse automatically refactor if it can. The result would look like:

Klass my_klass = new Klass();

Eclipse has all sorts of nice refactoring features. Does it have this?

解决方案

• Right click on the constructor you want to remove -> Refactor -> Change method signature.
• Remove the paramaters you want (all of them in your case) and then your Eclipse will change all of your calls to this constructor automatically. If you already have a default constructor it will complain; just press Ok, it will give you a compilation error because you have two constructor with the same parameters,
• Make a merge or delete the old one and you have the result that you want.
