There's no difference between those two examples.
Second should work too, perhaps the accountId was not 12345 when you tested the second one? ;)

you may have to cast it as a string before the trim, like...

if(  ((String)(object.getAccountId())).trim().equals("12345"))

hi,

depending on what getAccountId returns :

/*** returns object : ***/
if (object.getAccountId().toString().trim().equals("12345"))
 System.out.print("12345");
else
 System.out.print("error");


/*** returns int or similar : ***/
if ((new Integer(object.getAccountId())).toString().trim().equals("12345"))
 System.out.print("12345");
else
 System.out.print("error");


is any of these better ?

stephane.
