autocompletion : Java Glossary
Autocompletion is a feature of word processors and data entry programs that means you don’t have to type an
entire word, just enough of it to resolve any ambiguities. Often the program will show you several possible
completions and let you click or arrow to select one rather than typing the whole word. This of course works best
in multiple choice situations. You might use autocompletion in a custom JComboBox
where the possibilities are fixed at compile time, or are dynamically determined from a database.
