Trim funcation

Helli,

i am trying to trim the user name. But when I call "trim" it shows me error.

MyCode:
import java.lang.String.*;
import java.text.DecimalFormat;
import java.text.ParsePosition;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Calendar;
import java.util.Date;
import java.util.GregorianCalendar;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.SimpleTimeZone;
import java.util.TimeZone;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

public final class AppUtil {
// so that nobody can accidentally create an AppUtil object
private AppUtil()
{
}

/**
* formatName - formats a name string given the individual name fields
*/
static public String formatName(String lastName, String firstName, String middleName, String suffix)
{
return AppUtil.trim(lastName) + ", " + AppUtil.trim(firstName) + " " + AppUtil.trim(middleName) + " " + AppUtil.trim(suffix);
}

}

Thanks

what would that error be?

I can guess...

Well error is "The method trim(String) is undefined for the type AppUtil"

So what is that telling you? You are calling the trim() method of the AppUtil class.

That appears to be YOUR class. Have you defined a trim method in your class, that takes a string as a parameter?

You need to use the trim method of String, not the trim method of AppUtil, which does not exist.

So:

return lastName.trim() + ", " firstName.trim() + " " + middleName.trim() + " " + suffix.trim();

How would you know? The AppUtil class is presumably a class written by, or in use by, the original poster.

Depending on what it does, the String.trim() may or may not be equivalent.

i would not sue him for this

i have also my "wild guess" that the original poster wanted to use the String's trim() method.

Hi ,

Thanks a lot for your reply and you are correct that I want to use trim from String.

Once again thanks for help !!!

And Jiri I am not him

I am her

Oh, also you never need to import the java.lang.*; as far as I know... Such as:

import java.lang.String.*;

And you should consider just doing:

import java.util.*;

But that's just my opinion

Well, that leaves a reader guessing exactly what's being used from java.util, and opens a door for name collisions.

ok Well I got my mistake.. Thanks a lot for help
