## The for Statement

> The `for` statement provides a compact way to iterate over a range of values. The general form of the `for` statement can be expressed like this:

> >     for (initialization; termination; increment) {
> >         statement
> >     }

> initialization is a statement that initializes the loop--its executed once at the beginning of the loop. termination is an expression that determines when to terminate the loop. This expression is evaluated at the top of each iteration of the loop. When the expression evaluates to `false`, the loop terminates. Finally, increment is an expression that gets invoked for each iteration through the loop. Any (or all) of these components can be empty statements.

> Often `for` loops are used to iterate over the elements in an array, or the characters in a string. The sample shown below, `ForDemo`, uses a `for` statement to iterate over the elements of an array and print them:

> >     public class ForDemo {
> >         public static void main(String[] args) {
> >             int[] arrayOfInts = { 32, 87, 3, 589, 12, 1076,
> >                                   2000, 8, 622, 127 };

> >             for (int i = 0; i < arrayOfInts.length; i++) {
> >                 System.out.print(arrayOfInts[i] + " ");
> >             }
> >             System.out.println();
> >         }
> >     }
