Class
java.util.ArrayList is very useful class for storing objects. It is replacement for
Vector class.
ArrayList supports null values and duplicates.
/* -- ArrayList creating */
ArrayList ar = new ArrayList();
/* -- add items */
ar.add( "One" );
ar.add( "Two" );
ar.add( "Two" );
ar.add( null );
ar.add( "Three" );
ar.add( null );
/* -- get and write second item */
System.out.println( ar.get( 1 ).toString() );
/* -- write all items */
System.out.println( ar.toString() );
Output is:
Two
[One, Two, Two, null, Three, null]
