Java Program to print star pattern-pyramid

Welcome,

Let's learn how to write a Java code for star patter (Pyramid) by taking input from user(using scanner).

First let's do this..

a) Pattern 1

Pattern 1

         

This is a simple pyramid pattern and you can understand very easily.

import java.util.*;
public class Pattern1 {
    public static void main(String args[]){
        Scanner sc=new Scanner(System.in);
        int n=sc.nextInt();
        for(int i=0;i<n;i++){
            for(int st=0;st<=i;st++){
                System.out.print("*");
            }
            System.out.println();
        }
    }
}
  

b) pattern 2

Pattern 2

        

It's very simple once you understand it.

import java.util.*;
public class Pattern2 {
    public static void main(String args[]){
        Scanner sc=new Scanner(System.in);
        int n=sc.nextInt();
        for(int i=n;i>0;i--){
            for(int st=i;st>0;st--){               
                  System.out.print(" * ");
            }           
          System.out.println();
        }
    }   
}

Thank you🙏
