java - trimming a string plus checking if string is not empty -

i have array list in objects stored, , object's getters string value shown below

list<abcd> hgfer = (list<abcd>)getter.rows(jhfile);             for(abcd f: hgfer)             {                        string p = f.getfromarea() 

as shown above array list , values extracting. have make sure string getting not empty plus should trimmed, achieved shown below:

p.getfromarea().trim().length() > 0 

now there several getters attached object return string. every individual string have this. thinking make separate individual method return boolean value , string parameter pass.for ex:

 private string validaterow(string g)   {   boolean valid = false;'   try{   **//code check should not empty plus should trim one**    }   catch(){}   valid = false;     }   

and have make call method somewhere within class

list<abcd> hgfer = (list<abcd>)getter.rows(jhfile);             for(abcd f: hgfer)             {                         if (!validaterow(f.getfromarea())            {//customised message             }            else            continue; 

now please advise how achieve string should not empty plus should trim one

you can try this:-

public boolean isnullorempty(string str) {     return (str == null) || (str.trim().length() == 0); } 

this return true if string null or empty, else false.
