Work off these:

class nested1
{
  public static void main (String[] args) throws java.lang.Exception
   { 
     int row=1;  int col=0; char ast='*'; // Declare and initialize loop counter
     while (row < 6) 
     { // Test and Loop
       System.out.println(row);
       col=0;  
       while (col<row) { System.out.print(ast); col++; }
       System.out.println();
       row++;     // Increment Loop Counter
     }
     System.out.println();  // Finish the line 
   }
}
