In this tutorial, we will discuss Hollow Pyramid Pattern in Java using nested while loop
In this program, we are going to learn about how to display Pyramid Pattern in Java using nested while loop in Java programming language
Here, we display an Hollow Pyramid Pattern program with coding using nested while loop and also program get input from the user using Scanner class function in Java language
The user can provide numbers as they wish and get the Hollow pyramid pattern according to their input.
Program 1
Hollow Pyramid triangle star pattern
import java.util.Scanner;//import the scanner class class Pyramid_WhileH1{ public static void main(String args[]){ Scanner scan=new Scanner(System.in); //create a scanner object System.out.print("Enter the number of rows"); int rows=scan.nextInt(); int i,j,k; i=1; while(i<=rows){ j=i; while(j<rows){ System.out.print(" "); j++; } k=1; while(k<2*i){ if(i==rows || (k==1 || k==2*i-1)) System.out.print("*"); else System.out.print(" "); k++; } i++; System.out.print("\n");//Move to the next line for print } } }
When the above code is executed, it produces the following results
Program 2
Inverted Hollow Pyramid triangle star pattern
import java.util.Scanner;//import the scanner class class Pyramid_WhileH{ public static void main(String args[]){ Scanner scan=new Scanner(System.in); //create a scanner object System.out.print("Enter the number of rows"); int rows=scan.nextInt(); int i,j,k; i=rows; while(i>=1){ j=rows; while(j>i){ System.out.print(" "); j--; } k=1; while(k<2*i){ if(i==rows || (k==1 || k==2*i-1)) System.out.print("*"); else System.out.print(" "); k++; } i--; System.out.print("\n");//Move to the next line for print } } }
When the above code is executed, it produces the following results
