In this tutorial, we are going to write a Java program to print a pyramid of numbers using for loop in Java Programming with practical program code and step-by-step full complete explanation.
Java program to print a pyramid of numbers using for loop.
import java.io.BufferedReader; import java.io.InputStreamReader; public class GeneratePyramidExample { public static void main (String[] args) throws Exception { BufferedReader keyboard = new BufferedReader (new InputStreamReader(System.in)); System.out.println("Enter Number:"); int as= Integer.parseInt (keyboard.readLine()); System.out.println("Enter X:"); int x= Integer.parseInt (keyboard.readLine()); int y = 0; for(int i=0; i<= as ;i++) { for(int j=1; j <= i ; j++) { System.out.print(y + "t"); y = y + x; } System.out.println(""); } } }
Output
Enter Number: 5 Enter X: 10 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140
