Question

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?

Answer 1

• 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.
