Question

Provide Java code to illustrate how to create an array, reference an array, and address an element of an array.

Answer 1

Hi!

To create an array:

type[] varname OR type varname[]

where:

• type is the class of the array.
• var-name is the name of the variable.
• [] indicates that the instance would be an array.

Examples:

float floatArray[];

boolean[] booleanArray;

String[] stringArray;

Object objectArray[];

To reference an array:

type varname1[];

type varname2[] = varname1;

where:

• After assign varname1 to varname2, varname2 points to the elements of varname1;

To address an element in an array:

type varname[n];

type i = varname[i];

If you want to access to the i element of the array you can do : varname[i];
