:The <code>for</code> keyword is used to create a [[for loop]], which specifies a variable initialization, a [[boolean expression]], and an incrementation. The variable initialization is performed first, and then the boolean expression is evaluated. If the expression evaluates to <code>true</code>, the block of statements associated with the loop are executed, and then the incrementation is performed. The boolean expression is then evaluated again; this continues until the expression evaluates to <code>false</code>.<ref name="for">{{cite web |title=The for Statement |url=http://java.sun.com/docs/books/tutorial/java/nutsandbolts/for.html |work=The Java Tutorials |publisher=Sun Microsystems, Inc. |date=February 14, 2008 |accessdate=2008-12-03}}</ref>
