Generate Pyramid For a Given Number in Java

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class GeneratePyramidExample {
      public static void main (String[] args) throws Exception{
            BufferedReader br= new BufferedReader (new InputStreamReader(System.in));
                System.out.println("Enter Number:");
                     int as= Integer.parseInt (br.readLine());
                         System.out.println("Enter X:");
                             int x= Integer.parseInt (br.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("");
         }

    }
}
