<h3>e1087. Using the \cv{for} Statement for Array Iteration [5.0]</h3>
The <code>for</code> statement can be used to conveninently iterate over the
elements of an array. The general syntax of the array-based <code>for</code>
statement is:
<pre> for (<font color="#0066ff"><i>type</i></font> <font color="#0066ff"><i>variable</i></font> : <font color="#0066ff"><i>array</i></font>) {
<font color="#0066ff"><i>body-code</i></font>
}
</pre>
The array-based <code>for</code> statement has four parts. The <font color="#0066ff"><i>array</i></font>
is an expression that returns an array. The <font color="#0066ff"><i>type</i></font> specifies the
type of <font color="#0066ff"><i>variable</i></font> which will be used to hold elements from the
array. In particular, <font color="#0066ff"><i>variable</i></font> always holds the current
element of the iteration and can be used by the code in
<font color="#0066ff"><i>body-code</i></font>. <font color="#0066ff"><i>body-code</i></font> is code that will be executed once
for every element in the array. Here is an example of the <code>for</code>
statement.
<pre> // Returns the smallest integer in the supplied array
public int getMin(int[] ints) {
int min = Integer.MAX_VALUE;
for (int num : ints) {
if (num < min) {
min = num;
}
}
return min;
}
</pre>
