Question

Loops: Write a program that uses a loop to diplay Pattern A below, followed by another loop that displays Pattern B. 

Answer 1

public class Pattern {

      public static void main(String[] args) {

            // TODO Auto-generated method stub

            //Printing Pattern A

            //Using two for loops for the given scenario

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

            for(int i = 1; i<=10; i++){

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

                        System.out.print("+");

                  }

                  //Printing an empty line after each row

                  System.out.println();

            }

            System.out.println("\nPattern B: ");

            //Printing pattern B

            for(int i = 10; i>=1; i--){

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

                        System.out.print("+");

                  }

                  //Printing an empty line after each row

                  System.out.println();

            }

      }

}

Output:
