Help Tree Set

[ShuiYinDeng]

oldAccount text file is Nicholas, Diana, Eric,Andy, Alex , AMy
CurrentAccount text file is Andy Alex Amy Kelvin cherry Betty
import java.util.*;
import java.io.*;

public class Example2
{
public static void main(String[]args) throws IOException
{
System.out.print (" Old Account is: ");
System.out.println();
TreeSet<String> oldAcc = new TreeSet<String>();
Scanner oldacc = new Scanner(new FileReader("OldAccount.txt"));
while (oldacc.hasNext()) {
String Line =oldacc.nextLine();
oldAcc.add(Line);
}
System.out.println(oldAcc);
oldacc.close();

System.out.print (" Current Account is: ");
System.out.println();
TreeSet<String> CurrAcc = new TreeSet<String>();
Scanner curracc = new Scanner(new FileReader("CurrentAccount.txt"));
while (curracc.hasNext()) {
String Line1 =curracc.nextLine();
CurrAcc.add(Line1);

}
System.out.println(CurrAcc);
curracc.close();


TreeSet<String> GradAcc = new TreeSet<String>();

GradAcc.addAll(oldAcc);
GradAcc.removeAll(CurrAcc);
System.out.print("The Grad Account is " + GradAcc);

}
}


The out put of GradAcc should is Diana , Eric , Nicholas
But My output is Alex ,Andy , Diana , Eric , Nicholas

any solution to solve???

As suggested at Daniweb, try using trim on the Strings before adding them to the sets.

First you need to split the input line from the file into strings, and add the strings to the Treeset...
