  I have a grails app (v 1.1.2) the logging is working fine from the groovy classes, but I can't get it to work from within a java source...

• Any reason to clean up unused imports in Java, other than reducing clutter?

  - by Kip

  Is there any good reason to avoid unused import statements in Java? As I understand it, they are there for the compiler, so lots of unused imports won't have any impacts on the compiled code. Is it just to reduce clutter and to avoid naming conflicts down the line? (I ask because Eclipse gives a warning about unused imports, which is kind of annoying when I'm developing code because I don't want to remove the imports until I'm pretty sure I'm done designing the class.)

• Does the List in .NET work the same way as arraylist in Java?

  - by eflles

  When I learned Java, I was told that the arraylist works this way: It creates an array with room for 10 elements. When the 11th element is added, it is created a new list with room for 20 elements, and the 10 elements are copied into the new array. This will repeat as until there are no more elements to add, or to a maximum size. Is the List in .NET constructed the same way?
