0056 Using the Comma
<![CDATA[
Java allows two or more variables to control a for loop.
And you can include multiple statements in both the initialization and iteration portions of the for.
Each statement is separated from the next by a comma.
Here is an example:
public class Main {
public static void main(String args[]) {
for (int a = 1, b = 4; a < b; a++, b--) {
System.out.println("a = " + a);
System.out.println("b = " + b);
}
}
}
The program generates the following output:
a = 1
b = 4
a = 2
b = 3
