Question

“Refer to objects by their interfaces” is a good practise, as mentioned in Effective Java.
So for example i prefer

List<String> al = new ArrayList<String>();

over

ArrayList<String> al = new ArrayList<String>();

in my code. One annoying thing is that if i type ArrayList<String> al = new and then hit Ctrl+Space in Eclipse i get ArrayList<String>() as propostal. But if i type List al = new and then hit Ctrl+Space i will get only propostal to define anonymous inner class, but not propostals such as new ArrayList<String>(), what is 99% the case, or for example new Vector<String>().

Question: Is there any way to get the subclasses as propostals for generic types?

Answer 1

I would suggest simply writing the expression first and then hitting Ctrl+2, L. Then you can name the variable, followed by Enter, Down, Enter. Done.
