String list = new String;
The array object has three cells.
Once an array object has been constructed, the number of cells does not change. You must construct an array with a length that will accommodate all the data you expect. Unfortunately, sometimes this length is hard to determine. A program might need different sizes each time it is run. It would be nice if there were a type of array that allowed you to keep adding data regardless of its original length.
Vocabulary Review: A cell of an array is a place where data may be stored. An array may contain many cells. The cells are numbered from 0 up to one less than the length of the array. (Sometimes cells are called slots.)
An element is the data that has been placed in a cell. (Sometimes an element is called an item, a value, or an entry.)
An array has been completely filled with information:
String list = new String; list = "ant" ; list = "bat" ; list = "cat" ;
After running for a while, the program needs to add information to the array. Will the following statement make the array larger?
list = new String;
