Local variable or parameter can be 'final'

Reports parameters or local variables that may have the final modifier added to their declaration.

Example:

ArrayList<Integer> list = new ArrayList();
fill(list);
return list;

After the quick-fix is applied:

final ArrayList<Integer> list = new ArrayList();
fill(list);
return list;

Use the inspection's options to define whether parameters or local variables should be reported.
