To preparing for OCAJP 7, candidates should read a lot of reference material. The following tips helps you to prepare "Creating and Using Arrays" OCAJP exam objective.

What is Array?

An array is a data structure that stores a group of data of the same type.

To access elements in an array, we can use of reference with an integer index value.

They can be one dimensional or multi dimensional.

Arrays are really objects.

Arrays can hold primitives and object references.

How to access array elements?

Indexing of array elements start with index value "0".

Last index value of the array element is one less than the length of the array.

If length of the array is 10 then the last index will be 9.

When array object get created in the heap, elements will take their default values.

Declaring an array:

For one dimensional array, which can hold integers, both of followings are legal.

int [] myArray; // placing square brackets between the name and the data type is recommended.

int myArray []; // placing square brackets like here is not recommended as less readability but is completely legal.

For one dimensional array, which can hold String objects, both of followings are legal.

String [] myArray; // placing square brackets between the name and the data type is recommended.

String myArray []; // placing square brackets like here is not recommended as less readability but is completely legal.
