Pyramid-Pattern

A simple java program on pyramid pattern.
To make the program simple we did not use any Scanner class for input.
For loop is being used mainly.

for(i=1;i<=n;i++)
		{
		for(j=1;j<=l;j++)
		{
		System.out.print(" ");
		}
		  for(k=1;k<=2*i-1;k++)
    		{
	    	System.out.print("*");
		    }
  		l--;
	  }

in the last for loop we have used the formula

		for(k=1;k<=2*i-1;k++)

since we need a pyramid pattern of

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

which is of the order 2*i-1.
