Java code to Hollow Pyramid Pattern

Java code to Hollow Pyramid Pattern

In this tutorial, we will discuss Java code to Hollow Pyramid Pattern in Java language

In this topic, we will learn how to create te hollow pyramid star pattern in Java programming  language

Hollow Pyramid pattern

Program 1

This program allows the user to enter the number of rows then it will display hollow pyramid star pattern using for loop in Java language

import java.util.Scanner;
class Hollow_Pyramid1{
public static void main (String args[]){
Scanner sc=new Scanner(System.in);
System.out.print("Enter the rows: ");
int rows=sc.nextInt(); //get input from user
for(int i=1; i<=rows; i++){//Print each row 
for(int j=i; j<rows; j++){//Print space for Pyramid shape 
System.out.print(" "); 
} 
for(int k=1; k<2*i; k++){//print *
if(i==rows || (k==1 || k==2*i-1))
 System.out.print("*"); 
 else {
 System.out.print(" "); 
 }

}
 System.out.println(""); //move to next line
}
}
}

When the above code is executed, it produces the following results:

 

Hollow inverted Pyramid pattern

Program 2

This program allows the user to enter the number of rows then it will display hollow inverted pyramid star pattern using for loop in Java language

import java.util.Scanner;
class Hollow_Pyramid2{
public static void main (String args[]){
Scanner sc=new Scanner(System.in);
System.out.print("Enter the rows: ");
int rows=sc.nextInt();   //get input from user
for(int i=rows; i>=1; i--){//Print each row 
for(int j=rows; j>i; j--){//Print space for Pyramid shape 
System.out.print(" "); 
} 
for(int k=1; k<2*i; k++){//print *
if(i==rows || (k==1 || k==2*i-1))
 System.out.print("*"); 
 else {
 System.out.print(" "); 
 }

}
 System.out.println(""); //move to next line
}
}
}

When the above code is executed, it produces the following results:
