7.6. Enhanced for Statement

In previous examples, we demonstrated how to use counter-controlled for statements to iterate through the elements of an array. In this section, we introduce the enhanced for statement, which iterates through the elements of an array or a collection without using a counter (thus avoiding the possibility of “stepping outside” the array). This section discusses how to use the enhanced for statement to loop through an array. We show how to use the enhanced for statement with collections in Chapter 19, Collections. The syntax of an enhanced for statement is:

for ( parameter : arrayName )
   statement

where parameter has two parts—a type and an identifier (e.g., int number)—and arrayName is the array through which to iterate. ...
