title: Importing classes with * in Java instead of listing them specifically
body: <p>If you had a single class you needed to import, say java.util.Random, would naming it specifically in the import statement like
      import java.util.Random;
  use less memory than
      import java.util.*;
  And would this change if you were using multiple classes from java.util? How about if you were using all the classes in java.util?</p>
