Automatic variable expansion in IntelliJ

Question

I'm working at a Java shop this summer and I'm coming from a C# job. I got super used to just typing var x = randomMethod(); In IntelliJ is there anyway to type something like this and then have it automatically expanded to the correct return type after hitting enter. So something like var x = newStringList(); becomes List<String> x = newStringList();

Answer 1

Rumel, welcome to the java world, and this one is easy...

First, type the method name (start typing it and use Ctrl + Space to autocomplete, if you like...)

newStringList()

With your cursor still on the method, or the parenthesis, now hit Ctrl + Alt + V (refactor: Introduce Variable ) and type the variable name you want (instead of the default, which is strings ).

List<String> strings = newStringList();

Good luck!
