Answer 1

$\text{\large\bf Algorithm}$

    $\textsf{\textemdash \: Setting the initial pattern/line.}\\\textsf{\textemdash \: Adding new dots after and before the two right-triangles respectively.}\\\textsf{\textemdash \: Deleting two dots in the middle to make a pyramid pattern.}\\\textsf{\textemdash \: } {\sf Rep eating} \textsf{ until the pattern is complete.}$

Answer 2

Solution:

Here comes my approach.

public class Pattern    {

   public static void main(String args[]){

       int i;

       for(i=1;i<=4;i++){

           dots(1,i);

           spaces(i,3);

           dots(i,4);

           spaces(3,2*i);

           dots(i,4);

           spaces(i,3);

           dots(1,i);

           System.out.println();

       }

   }

   static void dots(int i,int j){

       for(int k=i;k<=j;k++)

           System.out.print(".");

   }

   static void spaces(int i,int j){

       for(int k=i;k<=j;k++)

           System.out.print(" ");

   }

}

There are two functions - dots(i,j) and spaces(i,j).

• dots(): This function creates dots in the pattern.
• spaces(): This function creates spaces between the dots where necessary.

Both functions are called inside the loops. Hence the pattern is printed.

See the attachment for output.
