List : Java Glossary


list
The word list in Java is only slightly less vague than the word thing. It has many meanings:
  1. The traditional computer science meaning is a group of objects linked together in a chain by references.
  2. The angle a boat tilts in the water.
  3. A prioritised todo list.
  4. java.awt.List, a scrolling list of choices from which you can select one. Like a Choice displayed already opened up. Further, it allows multiple selections if you use setMultipleMode( true ).
  5. java.util.List is an interface implemented by LinkedList, ArrayList and Vector that characterises array-like collections. You can convert an ordinary array into a List with Arrays.asList(myArray). A List is a Collection, but it is not a Set. Lists can have duplicates; Sets cannot.
  6. In dbAnywhere, a List is group of columns in an SQL (Standard Query Language) table.

You can check if a List is in order with com.mindprod.common15.InOrder.
