For Loop

Given below is example of For Loop. To print a series of Asteric (*) symbol in right angle triangle shape. We can make all other type of triangles using for loop or other loops(While or Do While). This is very interesting program for beginners :-)

class Triangle
{
           public static void main(String args[])
           {
                      int i, j;
                      for(i = 0; i <= 5; i++)
                      {
                                 for(j = 0; j <= i; j++)
                                 {
                                            System.out.println(" * ");
                                 }
                                 System.out.println();
                      }
           }
}


Output :

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