Java™ How To Program (Early Objects), Tenth Edition

Section 7.3 Declaring and Creating Arrays

• To create an array object, specify the array’s element type and the number of elements as part of an array-creation expression (p. 246) that uses keyword new.

• When an array is created, each element receives a default value—zero for numeric primitive-type elements, false for boolean elements and null for references.

• In an array declaration, the type and the square brackets can be combined at the beginning of the declaration to indicate that all the identifiers in the declaration are array variables.

• Every element of a primitive-type array contains a variable of the array’s declared type. Every element of a reference-type array is a reference to an object of the array’s declared type.
