*
***
*****
*******
*********
***********
solution:

public class range {

public static void main ( String args [] ) {

int i,j;

for(i=1;i<=11;i+=2){

for(j=1;j<= i;j++){

System.out.print("*");}

System.out.print("\n");}}}

*************************

Write a program to ask the user to enter a positive integer N and then compute N! using afor loop to repeatedly multiply numbers from 1 to N to a value.

solution:

import javax.swing.*;

public class range {

public static void main (String args[]){

int limit = 0;int result = 1;

limit = Integer.parseInt(JOptionPane.showInputDialog( "Enter limit"));

for(int i=1;i<=limit;i++){

result *= i;}

System.out.print(result);
}}
