JulsSmile [24]

Answer:

public class Pyramid {

   public static void main(String[] args) {

             int h = 7;

       System.out.println("Pattern A");

               for(int i = 1; i <= h; ++i)

               {

                   for(int j = 1; j <= i; ++j) {

                       System.out.print("+");

                   }

                   System.out.println();

               }

       System.out.println();

       System.out.println("Pattern B");

               for (int i = 1; i<=h; ++i)

               {

                 for(int j = h; j >=i; --j){

                     System.out.print("+");

                 }

                   System.out.println();

               }

           }

       }

Explanation:

  • The trick in this code is using a nested for loop
  • The outer for loop runs from i = 0 to the heigth of the triangle (in this case 7)
  • The inner for loop which prints the (+) sign runs from j = 0 to j<=i
  • It prints the + using the print() function and not println()
  • In the pattern B the loop is reversed to start from  i = height
