Objectives

To describe why arrays are necessary in programming (§7.1). ■

To declare array reference variables and create arrays (§§7.2.1-7.2.2).

■

To obtain array size using arrayRefVar.length and know default
values in an array (§7.2.3).

■

To access array elements using indexes (§7.2.4).

■

To declare, create, and initialize an array using an array initializer (§7.2.5).

■

To program common array operations (displaying arrays, summing
all elements, finding the minimum and maximum elements, random
shuffling, and shifting elements) (§7.2.6).

■

To simplify programming using the for each loops (§7.2.7).

■

To apply arrays in application development ( AnalyzeNumbers ,
DeckOfCards ) (§§7.3-7.4).

■

To copy contents from one array to another (§7.5).

■

To develop and invoke methods with array arguments and return values
(§§7.6-7.8).

■

To define a method with a variable-length argument list (§7.9). ■

To search elements using the linear (§7.10.1) or binary (§7.10.2)
search algorithm.

■

To sort an array using the selection sort approach (§7.11).

■

To use the methods in the java.util.Arrays class (§7.12).

■

To pass arguments to the main method from the command line (§7.13).
