TIP 1 : Always use String.length() == 0 to check if String is empty

There are many ways to compare the empty string in java and a usual approach is use below code

 String str = "";  
 if(str.equals(""))  
 {  
   //do something  
 }else{  
  //do else  
 }  

Well, don't do this ever in future. It cost your very high. See the analysis in given link in my another blog.
