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

Section 7.7 Enhanced for Statement

• The enhanced for statement (p. 262) allows you to iterate through the elements of an array or a collection without using a counter. The syntax of an enhanced for statement is:

for (parameter : arrayName)   statement

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

• The enhanced for statement cannot be used to modify elements in an array. If a program needs to modify elements, use the traditional counter-controlled for statement.
