Question:- Write a program that displays the following pattern:



*

***

*****

*******

*****

***

*



Output. Seven lines of output as follows: The first consists of 3 spaces followed by a star. The second line consists of 2 spaces followed by a 3 stars. The third consists of one space followed by 5 stars, and the fourth consists just of 7 stars. The fifth line is identical to third, th sixth to the second and the seventh to the first.



CLASS NAMES. Your program class should be called StarPattern

 

Complete solution below:-





public class StarShapePattern {

//the main method

                        public static void main(String[] aug) {

                        final int rowVal = 7;

                        int spacesVal = rowVal/2;

                        int  starsNum= 1;

                        //this loop works on the rows of pattern.

                        for(int j = 0; j < rowVal; j ++){

                                    //this loop works on the one row how spaces are there many patterns.

                        for(int k = 0; k < spacesVal; k ++){

                        System.out.print("");

                        }

                        //this loop works on the one row how stars are there many patterns.

                        for(int k = 0; k < starsNum; k ++){

                        System.out.print("*");

                        }

                        //after every row complete there should be a new line.

                        System.out.println();

                        if(j< rowVal/2){

                        spacesVal--;

                        starsNum+= 2;

                        }

                        else{

                        spacesVal++;

                        starsNum-= 2;

                        }

                        }

                        }

                        

}
