In this article, we will learn to print the different Pyramid Pattern in Java. The pattern programs will help you to master nested loops and recursion in Java. This is one among the popular Java interview questions for fresher. Let’s look into the different Pyramid Program in Java
Pyramid Program in Java
Pattern 1
package com.javainterviewpoint;
import java.util.Scanner;
public class Pattern1
{
public static void main(String[] args)
{
// Create a new Scanner object
Scanner scanner = new Scanner(System.in);
// Get the number of rows from the user
System.out.println("Enter the number of rows needed in the pattern ");
int rows = scanner.nextInt();
System.out.println("** Printing the pattern... **");
for (int i = 1; i <= rows; i++)
{
for (int j = rows; j > i; j--)
{
System.out.print(" ");
}
for (int k = 1; k <= i; k++)
{
System.out.print(i + " ");
}
System.out.println();
}
}
