pyramid pattern in java
// Java implementation to print the // following pyramid pattern public class Pyramid_Pattern { // function to print the following pyramid // pattern static void printPattern(int n) { int j, k = 0; // loop to decide the row number for (int i = 1; i <= n; i++) { // if row number is odd if (i % 2 != 0) { // print numbers with the '*' // sign in increasing order for (j = k + 1; j < k + i; j++) System.out.print(j + "*"); System.out.println(j++); // update value of 'k' k = j; } // if row number is even else { // update value of 'k' k = k + i - 1; // print numbers with the '*' in // decreasing order for (j = k; j > k - i + 1; j--) System.out.print(j + "*"); System.out.println(j); } } } // Driver program to test above public static void main(String args[]) { int n = 5; printPattern(n); } }
