Arrays

• Array elements are zero-based.

• Java implicitly creates an array class for each class that is defined, and for the simple data types.
• All array classes descend from the class Object, and mirror the hierarchy of the classes they contain.

• Arrays are static (rather than dynamic); can't add an arbitrary number of elements to an existing array.

// Declare the array
SomeClass[] myArray;

// Create a reference for each element
myArray = new SomeClass[10];

// Or Combine the declaration and reference creation
SomeClass[] myArray = new SomeClass[10];

// Allocate the elements of the array (not needed for simple data types)
for (int i = 0; i < myArray.length; i++)
    myArray[i] = new SomeClass;

Alternate syntax for declaring arrays

SomeClass myArray[];
