Let's say I have the following in a method.

int i;

Then, I type "j = i;"  The variable j is not declared.  So, the editor should automatically add the type in front of j or add the declaration at the top of the method.  Such as shown below.

int i, j;

j = i;

This could be done when assigning a variable to:

- the return value of a method
- a member variable
- a static variable
- a "new some_object_type();"
- a "new some_object_type[];"

Why bother the engineer with types when the editor can automatically do it?

Reproducible: Always

You can use one of the quick fixes offered for the error on 'j' - 'Create local variable', 'Create Field' or 'Create parameter'. Is using a quick fix too hard ?

It is not clear about what the developer wants to do in each and every situation, hence I would not start creating declarations automatically.

At best we may possibly show the quick fix popup automatically, but even this is stretching things a bit.

I guess the current solution is good enough.
