Calling a method from a loop

A method call is a statement like any other, so it can go inside a loop. The method's lines are written once and run every time the loop comes round:

public class Main {
    public static void main(String[] args) {
        for (int round = 1; round <= 3; round++) {
            System.out.println("Round " + round);
            printDivider();
        }
    }

    public static void printDivider() {
        System.out.println("-----");
    }
}

Round 2

Round 3

Methods also make a program easier to change. To make the divider longer, you change one line in printDivider, and every call prints the new one.
