list

The word list in Java is only slightly less vague than the word thing. It has many meanings:

The traditional computer science meaning is a group of objects linked together in a chain by references.
LinkedList
The angle a boat tilts in the water.
A prioritised todo list.

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 ).

import java.awt.List;
...
List flavour = new List();

// adding possible choices
flavour.add( "strawberry" );
flavour.add( "chocolate" );
flavour.add( "vanilla" );

// setting the selection
flavour.select( 0 );
// there is no select( String )

// detecting the selection
String choice = flavour.getSelectedItem();
int which = flavour.getSelectedIndex();

// allowing multiple selections
flavour.setMultipleMode( true );
String choices[] = flavour.getSelectedItems();
int indexes[] = flavour.getSelectedIndexes();
// these is no select( int[] ) or select( String[] )
