String[] obj = new String[2] - it will create an array of strings with size 2 (so you can access obj[0], obj[1] only)

obj = formBean.getUserName() - you are changing the reference of obj from string array (which you created in above step) to the value returned from getUserName() method...

so aa method em return chesthe nee obj daaniki point chesthundi...
