Pyramid.java:

public class Pyramid {
    public static void main(String args[]) {
        int i, j;
        for (i = 1; i <= 5; ++i) {
            for (j = 1; j <= i; ++j) {
                System.out.print("*");
            }
            System.out.println();
        }
        /*print half pyramid with 5 rows */

        for (i = 4; i >= 1; --i) {
            for (j = 1; j <= i; ++j) {
                System.out.print("*");
            }
            System.out.println();
        }
