I tried printing Character.getType(test.charAt(i)) and it is always
9 indicating decimal digit. Can someone please clarify what's being
done wrong?
There is an error in your *real* code. My results don't agree with
yours, i.e. both posted examples work as advertised.
It would help if you posted an example of the string that gives the
strange result, and also indicated exactly where in the code you put
the call to getType(). In fact why not post a complete, compilable
example that exhibits the strange behaviour. Cut and paste!

The string is either an encrypted one or a number. I can't post the
encrypted ones. The number strings are like "012345". I put the
getType inside the for loop as follows:
for(int i=0; i < test.length(); i++) {
System.out.println("type=" +
Character.getType(test.charAt(i));
if (!Character.isDigit(test.charAt(i)) ) {
flg=1;
break;
}
}
Here is the complete code I am working with:
import java.io.*;
import java.util.*;
public class csv4{
public static Hashtable returns_apps = new Hashtable();
public static Hashtable returns_ssn= new Hashtable();
public static Hashtable returns_btn= new Hashtable();
public static Hashtable tzmap=new Hashtable();
public static void main( String [] args) {
String aline="";
try {
FileReader fr = new FileReader("return_ssn_020807.csv");
BufferedReader br = new BufferedReader(fr);
while ((aline = br.readLine()) != null) {
returns_apps.put(aline.trim(), "");
}
br.close();
fr = new FileReader(args[0]);
br = new BufferedReader(fr);
while ((aline = br.readLine()) != null) {
aline=aline.replaceAll(",", " , ");
//aline=aline.replaceAll("\"", "");
String [] aline_arr = aline.split(",");
if (aline_arr.length < 6) continue;
String ssn =aline_arr[5].trim();
int flg=0;
for(int i=0; i < ssn.length(); i++) {
System.err.println("char" +
Character.getType(ssn.charAt(i)));
System.err.println("i=" + i);
if (Character.isDigit(ssn.charAt(i)) )
continue;
flg=1;
break;
}
if (flg == 1) {
continue;
}
if (returns_apps.containsKey(ssn))
{
continue;
}
System.out.println(aline);
}
br.close();
} catch (Exception e) {
System.out.println("exception " + e.getMessage());
e.printStackTrace();
}
} //main
} //class
Thanks
