Java.text.DecimalFormat is parsing '22.3.6' !

I'm using DecimalFormat to mask a data entry field.
When I enter something like 22.3.6, it parses!
String docString = "22.3.6";
NumberFormat nFormat = new DecimalFormat();
float value = nFormat.parse(docString).floatValue();
System.err.println("value: " + value);
Gives me:
value: 22.3
I was expecting a NumberFormatException.
I'm running
build 1.5.0_05-b05
Should I enter this as a bug?

I tried yout code and it formats the String the way you wanted:
public class Test
public static void main ( String[] args )
java.text.DecimalFormat df2 = new java.text.DecimalFormat("###########0.00");
System.out.println(df2.format(java.lang.Float.parseFloat("-3.0")));
} //End Main
}

Java.text.DecimalFormat Error

I have this import directive in my jsp page.
<%@ page import="java.io.*,java.sql.*;java.text.DecimalFormat" contentType="text/html;charset=windows-1252"%>
I am using Jdeveloper 9i 9.0.3.
When I compile this page from within JDeveloper I get this error for java.text.DecimalFormat
Error: 'class' or 'interface' expected
When I compile outside JDeveloper, I get NO error.
Can somebody tell me what the problem is.

<%@ page import="java.io.*;java.sql.*;java.text.DecimalFormat" contentType="text/html;charset=windows-1252"%>
I think that missing semi-colon is what's creating problems for you.

Please help! java.text.ParseException:

Hi everybody
why am i gatting java.text.ParseException: Unparseable date: "Jul 21, 2002"
String s = "yyyy MM dd";
SimpleDateFormat ff = new SimpleDateFormat(s);
java.util.Date mm = ff.parse( DateFormat.getDateInstance().format(new java.util.Date())) ;
System.out.println(mm.toString()); //Exception is thrown
thanks in advence

I didn't take time to look through your code too closely but here is some code that might help. The pullDate method reads a string from a JTextField (textField) and tries to return a Date. If it can't format it then it returns null. It tries to format the text based on the formats listed. If it can't format the text using one then it tries the next until it runs out of them. Change the formats to whatever you like. Good luck.

     new DateFormatter(new SimpleDateFormat("M/d/yy")),

     new DateFormatter(new SimpleDateFormat("MMM d yy")),
     new DateFormatter(new SimpleDateFormat("d MMM yy"))};
private Date pullDate() {
     String text = textField.getText();
     Date d = null;
     int i = 0;
     while(d==null && i<altFormats.length) {
          try {
               d = (Date)(altFormats[i++].stringToValue(text));
          } catch (ParseException e) {}
     return d;

Java.text.DecimalFormat

hi folks,
I'm trying to format a floating point number so that it has exactly two digits after the decimal
DecimalFormat df=new DecimalFormat("##.00");
System.err.println(df.format(12.995));
My desired output is 12.99(truncation, no rounding)
the actual output is 13.00 (rounding)
how do I acheive what I what?
thank you!!

Since DecimalFormat uses ROUND_HALF_EVEN, you need to use something else. The java.math.BigDecimal class is something you could use:
double value = 12.995;
BigDecimal bd = new BigDecimal(value);
bd = bd.setScale(2, BigDecimal.ROUND_DOWN);
System.err.println(bd); This would print out 12.99.

Force 2 decimal places with java.text.DecimalFormat

Hi all,
I am trying to force 2 decimal places for sum of 2 doubles (please see my code below). According to the API javadoc this should always display 2 decimals, however at the moment if the second decimal is zero it gets chopped off:(
Any ideas what is going wrong?
Thanks,
Olli
public double sum(double valueOne,double valueTwo)
double sum=valueOne+valueTwo;
DecimalFormat forceDecimals=new DecimalFormat("0.00");
total=Double.parseDouble(forceDecimals.format(sum));
return sum;
}

Hi Olli,
you return sum and not total, but nevertheless returning a double doesn't help as 5.00 will always be 5.0.
An option would be to return the formatted String.

Please help with java.text.MessageFormat...

Hi all
I'm reasonably new to java and have been struggling with this one for a while. I wonder if anyone can help?
The following code...
Object[] testArgs = {new Long(1273), "MyDisk"};
MessageFormat form = new MessageFormat(
"The disk \"{1}\" contains {0} file(s).");
System.out.println(form.format(testArgs));
...gives the following output...
The disk "MyDisk" contains 1,273 file(s).
I simply want to get rid of the comma, so that the output becomes...
The disk "MyDisk" contains 1273 file(s).
Any ideas? Many thanks for reading my thread and for any help you may be able to offer!
Kind Regards
Jon

contains {0,number,#} file(s).

New java class - noob question

Hi all, my code isn't working and I think it could be because the necessary class isn't being imported. I don't really know how importing works (if there needs to be a particular file structure).
What is the problem here and how do I fix it? If it is down to importing the class, how exactly do I do that? I've tried:
import current_directory.class_name
import class_name
Both these files are in the same directory and I can get other code to compile and run.
Any advice would be greatly appreciated.
Cheers in advance.
MM :)
public class BigCorp{
     public static void main ( String [] args) {
          Person A = new Person();
          A.setFName("MyName");
          System.out.println(A.getFName);
//Person.java
public class Person {
String lName = new String();
String fName = new String();
static long population=0;
     public Person(){
          population++;
     public String getLName(){
          return lName;
     public void setLName(String lastName){
          lName = lastName;
     public String getFName(){
          return fName;
     public void setFName(String firstName){
          fName = firstName;
     public static long getPopulation(){
          return population;
     public void finalize(){
          population--;
}

You shouldn't need to import anything here.
You didn't say what the actual problem was but you implied it wasn't compiling. I'm guessing that's because
System.out.println(A.getFName);
should be
System.out.println(A.getFName());
since getFname is a method, it has to be called by getFName()
Also, you string variables can be declared as
String lname=" ";

Rounding problem with java.text.DecimalFormat

I see that the bug reported in relation to this (#4763975) has been closed.
I'm just wondering when will this bug be fixed or is it even scheduled to be fixed in the future?

Hi Olli,
you return sum and not total, but nevertheless returning a double doesn't help as 5.00 will always be 5.0.
An option would be to return the formatted String.

DecimalFormat question

Hey all
How do I use DecimalFormat in such a way that the there can be an arbitrary number of digits before the decimal point and a speciffied number after the point, the caveat being that the returned number use scientific notation where applicable. Ill clarify with example.
I want three digits after the decimal
double d = 1.2345e10
use some DecimalFormat magic should output
1.235e10
and not
12350000000.0
another ex)
d = 1.3243373628372937e8
outputs
132433736.284
and not
1.324e8
Thanx in advance

Huh?
import java.text.DecimalFormat;
public class PG
    public static void main(String[] args)
        DecimalFormat format = new DecimalFormat("0.###E0");
        System.out.println(format.format(132433736.284));
}prints:
1.324E8

Java.text.SimpleDateFormat millisecond problem...

When I run this code:
java.text.SimpleDateFormat formatter = new java.text.SimpleDateFormat();
formatter.applyLocalizedPattern("yyyy-MM-dd HH:mm:ss.000000");
java.util.Date date1 = formatter.parse("2001-08-14 13:49:38.000000", new java.text.ParsePosition(0) );
System.out.println("Date 1 = " + date1);
formatter.applyLocalizedPattern("yyyy-MM-dd HH:mm:ss.SSS000");
java.util.Date date2 = formatter.parse("2001-08-14 13:49:38.000000", new java.text.ParsePosition(0) );
System.out.println("Date 2 = " + date2);
The output is:
Date 1 = Tue Aug 14 13:49:38 GMT+01:00 2001
Date 2 = null
The only difference is in the localized pattern, date 1 is generated where milliseconds aren't in the localized pattern, date 2 is generated where milliseconds are in the localized pattern.
Why is date2 null????

Hi! When you use the second pattern, it appears that "yyyy-MM-dd HH:mm:ss.SSS000" is not an acceptable pattern. However, "yyyy-MM-dd HH:mm:ss.SSS" works. I'd hazard a guess that when you specify milliseconds, only three places are allowed.
If you used pattern #2 as you had specified originally, a java.text.ParseException is thrown. With the above modification, it works as expected.
Hope this helps!
Cheers!

I'am new at Java world, so please suggest me an IDE to work on .......

hi everybody !
This is my first post . I'am new in Java world, so please suggest me an IDE to work on ....... there are many IDE: Jbuilder, Jdevelopper, jRun, Sun Studio ... and then I don't know wich one is better (easer to use and to create good user interfaces), I'am designing a networking application surveying servers, hosts, routers ...and managing sms (sent to and received from Administrator).
The OS is Suse Linux Professsional, the DBSM is Oracle 10g .
I wait for your answers and thanks for your time

For a beginner JCreator is a nice but I think it is only for Windows.
For linux support have a a look at:
Netbeans:
If you are looking for GUI design features NetBeans 5.0 (hasn't been released yet, but you can download a beta version - release due in December) has a probably the best GUI designer. I would wait till the release version if I were your. It is also a solid IDE, but consumes a quite a bit of memory. Don't even consider this option unless you have 380MB+ RAM
www.netbeans.org
or
Eclipse
Very popular, uses less memory than NetBeans, but doesn't come with a GUI designer. Nice for editing code, but don't expect many fancy wizards.
www.eclipse.org. You can get away with about 256MB RAM.
If you intend to run Oracle 10g on the same system as these tools at the same time you better have a very impressive system, or will end up editor code in a text editor and compiling from the command line.

Java Spring - Please Suggest

Please suggest some good book for Java Spring
I found that Spring in Action tough for a beginner

You can expect any text on Spring to be relatively advanced, as they're not meant for entry level programmers.
You're expected to have a decent understanding of OO concepts especially.
But yes, the book I mentioned more or less eases you into the whole thing instead of plunging right in.
The book yawmark mentioned is more of a reference. I've not read it (though I've browsed some sections that I needed at times).
At the moment I'm working my way through Pro Spring MVC and Web Flow, not recommended as an introductory text on Spring (it assumes you already know the basics).
